The Ottoman Empire, historically also known as the Turkish Empire or Turkey, was a state that spanned much of Southeastern Europe, West Asia, and North Africa from the 14th century to the early 20th century, centred in modern-day Turkey. It also controlled parts of southeastern Central Europe between the early 16th and early 18th centuries.
The empire emerged from a beylik, or principality, founded in northwestern Anatolia in c. 1299 by the Turkoman tribal leader Osman I. His successors conquered much of Anatolia and expanded into the Balkans by the mid-14th century, transforming their petty kingdom into a transcontinental empire. The Ottomans ended the Byzantine Empire with the conquest of Constantinople in 1453 by Mehmed II. Further conquests by Selim I led the Sultans to adopt the title of caliph. With its capital at Constantinople and control over a significant portion of the Mediterranean Basin, the Ottoman Empire was at the centre of interactions between the Middle East and Europe for six centuries. Ruling over diverse peoples, the empire granted varying levels of autonomy to its many confessional communities, or millets, to manage their own affairs per Islamic law. During the reign of Suleiman the Magnificent in the 16th century, the Ottoman Empire became a global power.
Modern academic consensus posits that the empire began to decline after defeat in the Second Siege of Vienna in 1683, but continued to maintain a flexible and strong economy, society and military into much of the 18th century. The Ottoman Empire fell behind technologically from the rest of Europe by the late 18th century as imperial authority fragmented. Further defeats from Austria and Russia culminated in the loss of territory, and with rising nationalism after the French Revolution, a number of new states emerged in the Balkans. Following Mahmud II's reign and the Tanzimat reforms over the course of the 19th century, the Ottoman state became more powerful and organised internally as a new Ottoman identity took hold. In the 1876 revolution, the Ottoman Empire attempted constitutional monarchy, before reverting to an absolute monarchy under Abdul Hamid II, following the Great Eastern Crisis.
Over the course of the late 19th century, Ottoman intellectuals known as Young Turks sought to liberalise and rationalise society and politics along Western lines, culminating in the Young Turk Revolution of 1908 led by the Committee of Union and Progress (CUP), which reestablished a constitutional monarchy. However, following the disastrous Balkan Wars, the CUP became increasingly radicalised and embraced Turkish nationalism, leading to a coup d'état in 1913 that established a dictatorship.
In the 19th and in the start of 20th centuries, persecution of Muslims during the Ottoman contraction and in the Russian Empire resulted in large-scale loss of life and mass migration into modern-day Turkey from the Balkans, Caucasus, and Crimea. The CUP joined World War I on the side of the Central Powers. It struggled with internal dissent, especially the Arab Revolt, and engaged in genocide against Armenians, Assyrians, and Greeks. In the aftermath of World War I, the victorious Allied Powers occupied and partitioned the Ottoman Empire, which lost its southern territories to the United Kingdom and France. The successful Turkish War of Independence, led by Mustafa Kemal Atatürk against the occupying Allies, led to the end of the Ottoman sultanate in 1922.

Etymology
The word Ottoman is an historical anglicisation of the name of Osman I, the founder of the Empire and of the ruling House of Osman (also known as the Ottoman dynasty). Osman's name in turn was the Turkish form of the Arabic name ʿUthmān (عثمان). In Ottoman Turkish, the empire was referred to as Devlet-i ʿAlīye-yi ʿOsmānīye (دولت عليه عثمانیه), lit. 'Sublime Ottoman State', or simply Devlet-i ʿOsmānīye (دولت عثمانيه), lit. 'Ottoman State'.
The Turkish word for Ottoman (Osmanlı) originally referred to the tribal followers of Osman in the 14th century. The word subsequently came to be used to refer to the empire's military-administrative elite. In contrast, the term Turk (Türk) was used to refer to the Anatolian peasant and tribal population and was seen as a disparaging term when applied to urban, educated individuals. In the early modern period, an educated, urban-dwelling Turkish speaker who was not a member of the military-administrative class typically referred to himself neither as an Osmanlı nor as a Türk, but rather as a Rūmī (رومى), or "Roman", meaning an inhabitant of the territory of the former Byzantine Empire in the Balkans and Anatolia. The term Rūmī was also used to refer to Turkish speakers by the other Muslim peoples of the empire and beyond.
In Western Europe, the names Ottoman Empire, Turkish Empire and Turkey were often used interchangeably, with Turkey being increasingly favoured both in formal and informal situations. This dichotomy was officially ended in 1920–1923, when the newly established Ankara-based Turkish government chose Turkey as the sole official name.
History
Rise (c. 1299–1453)
As the Rum Sultanate declined in the 13th century, Anatolia was divided into a patchwork of independent Turkish principalities known as the Anatolian Beyliks. One of these, in the region of Bithynia on the frontier of the Byzantine Empire, was led by the Turkish tribal leader Osman I (d. 1323/4), a figure of obscure origins from whom the name Ottoman is derived. Osman's early followers consisted of Turkish tribal groups and Byzantine renegades, with many but not all converts to Islam. Osman extended control of his principality by conquering Byzantine towns along the Sakarya River. A Byzantine defeat at the Battle of Bapheus in 1302 contributed to Osman's rise. It is not well understood how the early Ottomans came to dominate their neighbours, due to the lack of sources surviving. The Ghaza thesis popular during the 20th century credited their success to rallying religious warriors to fight for them in the name of Islam, but it is no longer generally accepted. No other hypothesis has attracted broad acceptance.
In the century after Osman I, Ottoman rule had begun to extend over Anatolia and the Balkans. The earliest conflicts began during the Byzantine–Ottoman wars, waged in Anatolia in the late 13th century before entering Europe in the mid-14th century, followed by the Bulgarian–Ottoman wars and the Serbian–Ottoman wars in the mid-14th century. Much of this period was characterised by Ottoman expansion into the Balkans. Osman's son, Orhan, captured the northwestern Anatolian city of Bursa in 1326, making it the new capital and supplanting Byzantine control in the region. The important port of Thessaloniki was captured from the Venetians in 1387 and sacked. The Ottoman victory in Kosovo in 1389 effectively marked the end of Serbian power in the region, paving the way for Ottoman expansion into Europe. The Battle of Nicopolis for the Bulgarian Tsardom of Vidin in 1396, regarded as the last large-scale crusade of the Middle Ages, failed to stop the advance of the victorious Ottomans.
As the Turks expanded into the Balkans, the conquest of Constantinople became a crucial objective. The Ottomans had already wrested control of nearly all former Byzantine lands surrounding the city, but the strong defence of Constantinople's strategic position on the Bosporus Strait made it difficult to conquer. In 1402, the Byzantines were temporarily relieved when the Turco-Mongol leader Timur, founder of the Timurid Empire, invaded Ottoman Anatolia from the east. In the Battle of Ankara in 1402, Timur defeated Ottoman forces and took Sultan Bayezid I as prisoner, throwing the empire into disorder. The ensuing civil war lasted from 1402 to 1413 as Bayezid's sons fought over succession. It ended when Mehmed I emerged as the sultan and restored Ottoman power.
Expansion and peak (1453–1566)
The son of Murad II, Mehmed the Conqueror, reorganised both state and military, and on 29 May 1453 conquered Constantinople, ending the Byzantine Empire. Mehmed allowed the Eastern Orthodox Church to maintain its autonomy and land in exchange for accepting Ottoman authority. Due to tension between the states of western Europe and the later Byzantine Empire, most of the Orthodox population accepted Ottoman rule, as preferable to Venetian rule. Albanian resistance was a major obstacle to Ottoman expansion on the Italian peninsula.
In the 15th and 16th centuries, the Ottoman Empire entered a period of expansion. The Empire prospered under the rule of a line of committed and effective Sultans. It flourished economically due to its control of the major overland trade routes between Europe and Asia.
Sultan Selim I (1512–1520) dramatically expanded the eastern and southern frontiers by defeating Shah Ismail of Safavid Iran, in the Battle of Chaldiran. Selim I established Ottoman rule in Egypt by defeating and annexing the Mamluk Sultanate of Egypt and created a naval presence on the Red Sea. After this Ottoman expansion, competition began between the Portuguese Empire and the Ottomans to become the dominant power in the region.
Suleiman the Magnificent (1520–1566) captured Belgrade in 1521, conquered the southern and central parts of the Kingdom of Hungary as part of the Ottoman–Hungarian Wars, and, after his historic victory in the Battle of Mohács in 1526, he established Ottoman rule in the territory of present-day Hungary and other Central European territories. He then laid siege to Vienna in 1529, but failed to take the city. In 1532, he made another attack on Vienna, but was repulsed in the siege of Güns. Transylvania, Wallachia and, intermittently, Moldavia, became tributary principalities of the Empire. In the east, the Ottoman Turks took Baghdad from the Persians in 1535, establishing Ottoman rule in Iraq and gaining naval access to the Persian Gulf. After the end of the Ottoman–Safavid War (1532–1555), the Caucasus became partitioned for the first time between the Safavids and the Ottomans, a status quo that persisted until the Russian conquest of the Caucasus in the 19th century. By this partitioning as signed in the Peace of Amasya, Western Armenia, western Kurdistan, and Western Georgia fell into Ottoman hands, while southern Dagestan, Eastern Armenia, Eastern Georgia, and Azerbaijan remained Persian.
Stagnation and reform (1566–1827)
In the second half of the 16th century, the Ottoman Empire came under increasing strain from inflation and the rapidly rising costs of warfare that were impacting both Europe and the Middle East. These pressures led to a series of crises around the year 1600, placing great strain upon the Ottoman system of government. The empire underwent a series of transformations of its political and military institutions in response to these challenges, enabling it to successfully adapt to the new conditions of the 17th century and remain powerful, both militarily and economically. Historians of the mid-20th century once characterised this period as one of stagnation and decline, but this view is now rejected by the majority of academics.
The discovery of new maritime trade routes by Western European states allowed them to avoid the Ottoman trade monopoly. The Portuguese discovery of the Cape of Good Hope in 1488 initiated a series of Ottoman-Portuguese naval wars in the Indian Ocean throughout the 16th century. Despite the growing European presence in the Indian Ocean, Ottoman trade with the east continued to flourish. Cairo, in particular, benefitted from the rise of Yemeni coffee as a popular consumer commodity. As coffeehouses appeared in cities and towns across the empire, Cairo developed into a major centre for its trade, contributing to its continued prosperity throughout the seventeenth and much of the 18th century.
Under Ivan IV (1533–1584), the Tsardom of Russia expanded into the Volga and Caspian regions at the expense of the Tatar khanates. In 1571, the Crimean khan Devlet I Giray, commanded by the Ottomans, invaded Russia and burned Moscow. The next year, the invasion was repeated but repelled at the Battle of Molodi. The Ottoman Empire and its vassal, the Crimean Khanate, continued to invade Eastern Europe in a series of slave raids, and remained a significant power in Eastern Europe until the end of the 17th century. The Crimean cavalry became indispensable for the Ottomans' campaigns against Russia, Poland, Hungary, and Persia.
The Ottomans decided to conquer Venetian Cyprus and on 22 July 1570, Nicosia was besieged; 50,000 Christians died, and 180,000 were enslaved. On 15 September 1570, the Ottoman cavalry appeared before the last Venetian stronghold in Cyprus, Famagusta. The Venetian defenders held out for 11 months against a force that at its peak numbered 200,000 men with 145 cannons; 163,000 cannonballs struck the walls of Famagusta before it fell to the Ottomans in August 1571. The Siege of Famagusta claimed 50,000 Ottoman casualties. Meanwhile, the Holy League consisting of mostly Spanish and Venetian fleets won a victory over the Ottoman fleet at the Battle of Lepanto (1571), off southwestern Greece; Catholic forces killed over 30,000 Turks and destroyed 200 of their ships. It was a startling, if mostly symbolic, blow to the image of Ottoman invincibility, an image which the victory of the Knights of Malta over the Ottoman invaders in the 1565 siege of Malta had recently set about eroding. The battle was far more damaging to the Ottoman navy in sapping experienced manpower than the loss of ships, which were rapidly replaced. The Ottoman navy recovered quickly, persuading Venice to sign a peace treaty in 1573, allowing the Ottomans to expand and consolidate their position in North Africa.
Decline and modernisation (1828–1908)
During the Tanzimat period (1839–1876), the government's series of constitutional reforms led to a fairly modern conscripted army, banking system reforms, the decriminalisation of homosexuality, the replacement of religious law with secular law, and guilds with modern factories. The Ottoman Ministry of Post was established in Istanbul in 1840. American inventor Samuel Morse received an Ottoman patent for the telegraph in 1847, issued by Sultan Abdülmecid, who personally tested the invention. The reformist period peaked with the Constitution, called the Kanûn-u Esâsî. The empire's First Constitutional era was short-lived. The parliament survived for only two years before the sultan suspended it.
The empire's Christian population, owing to their higher educational levels, started to pull ahead of the Muslim majority, leading to much resentment. In 1861, there were 571 primary and 94 secondary schools for Ottoman Christians, with 140,000 pupils in total, a figure that vastly exceeded the number of Muslim children in school at the time, who were further hindered by the amount of time spent learning Arabic and Islamic theology. Author Norman Stone suggests that the Arabic alphabet, in which Turkish was written until 1928, was ill-suited to reflect the sounds of Turkish (which is a Turkic as opposed to Semitic language), which imposed further difficulty on Turkish children. In turn, Christians' higher educational levels allowed them to play a larger role in the economy, with the rise in prominence of groups such as the Sursock family indicative of this. In 1911, of the 654 wholesale companies in Istanbul, 528 were owned by ethnic Greeks. In many cases, Christians and Jews gained protection from European consuls and citizenship, meaning they were protected from Ottoman law and not subject to the same economic regulations as their Muslim counterparts.
The Crimean War (1853–1856) was part of a long-running contest between the major European powers for influence over territories of the declining Ottoman Empire. The financial burden of the war led the Ottoman state to issue foreign loans amounting to 5 million pounds sterling on 4 August 1854. The war caused an exodus of the Crimean Tatars, about 200,000 of whom moved to the Ottoman Empire in continuing waves of emigration. Toward the end of the Caucasian Wars, 90% of the Circassians were ethnically cleansed and exiled from their homelands in the Caucasus, fleeing to the Ottoman Empire, resulting in the settlement of 500,000 to 700,000 Circassians in the Ottoman Empire. Crimean Tatar refugees in the late 19th century played an especially notable role in seeking to modernise Ottoman education and in first promoting both Pan-Turkism and a sense of Turkish nationalism.
Defeat and dissolution (1908–1922)
The defeat and dissolution of the Ottoman Empire (1908–1922) began with the Second Constitutional Era, a moment of hope and promise established with the Young Turk Revolution. It restored the Constitution of the Ottoman Empire and brought in multi-party politics with a two-stage electoral system (electoral law) under the Ottoman parliament. The constitution offered hope by freeing the empire's citizens to modernise the state's institutions, rejuvenate its strength, and enable it to hold its own against outside powers. Its guarantee of liberties promised to dissolve inter-communal tensions and transform the empire into a more harmonious place. Instead, this period became the story of the twilight struggle of the Empire.
Members of Young Turks movement who had once gone underground now established their parties. Among them the Committee of Union and Progress and the Freedom and Accord Party were major parties. On the other end of the spectrum were ethnic parties, which included Poale Zion, Al-Fatat, and Armenian national movement organised under Armenian Revolutionary Federation. Profiting from the civil strife, Austria-Hungary officially annexed Bosnia and Herzegovina in 1908. The last of the Ottoman censuses was performed in 1914. Despite military reforms which reconstituted the Ottoman Modern Army, the Empire lost its North African territories and the Dodecanese in the Italo-Turkish War (1911) and almost all of its European territories in the Balkan Wars (1912–1913). The Empire faced continuous unrest in the years leading up to World War I, including the 31 March Incident and two further coups in 1912 and 1913.
The Ottoman Empire entered World War I on the side of the Central Powers and was ultimately defeated. The Ottoman participation in the war began with the combined German-Ottoman surprise attack on the Black Sea coast of the Russian Empire on 29 October 1914. Following the attack, the Russian Empire (2 November 1914) and its allies France (5 November 1914) and the British Empire (5 November 1914) declared war on the Ottoman Empire. Also on 5 November 1914, the British government changed the status of the Khedivate of Egypt and Cyprus, which were de jure Ottoman territories prior to the war, to British protectorates.
The Ottomans successfully defended the Dardanelles strait during the Gallipoli campaign (1915–1916) and achieved initial victories against British forces in the first two years of the Mesopotamian campaign, such as the Siege of Kut (1915–1916); but the Arab Revolt (1916–1918) turned the tide against the Ottomans in the Middle East. In the Caucasus campaign, however, the Russian forces had the upper hand from the beginning, especially after the Battle of Sarikamish (1914–1915). Russian forces advanced into northeastern Anatolia and controlled the major cities there until retreating from World War I with the Treaty of Brest-Litovsk following the Russian Revolution in 1917.
Historiographical debate on the Ottoman state
Several historians, such as British historian Edward Gibbon and the Greek historian Dimitri Kitsikis, have argued that after the fall of Constantinople, the Ottoman state took over the machinery of the Byzantine (Roman) state and that the Ottoman Empire was in essence a continuation of the Byzantine Empire under a Turkish Muslim guise. The American historian Speros Vryonis writes that the Ottoman state centred on "a Byzantine-Balkan base with a veneer of the Turkish language and the Islamic religion". Kitsikis and the American historian Heath Lowry posit that the early Ottoman state was a predatory confederacy open to both Byzantine Christians and Turkish Muslims whose primary goal was attaining booty and slaves, rather than spreading Islam, and that Islam only later became the empire's primary characteristic. Other historians have followed the lead of the Austrian historian Paul Wittek, who emphasises the early Ottoman state's Islamic character, seeing it as a "jihad state" dedicated to expanding the Muslim world. Many historians led in 1937 by the Turkish historian Mehmet Fuat Köprülü championed the Ghaza thesis, according to which the early Ottoman state was a continuation of the way of life of the nomadic Turkic tribes who had come from East Asia to Anatolia via Central Asia and the Middle East on a much larger scale. They argued that the most important cultural influences on the Ottoman state came from Persia.
The British historian Norman Stone suggests many continuities between the Byzantine and Ottoman empires, such as that the zeugarion tax of Byzantium became the Ottoman Resm-i çift tax, that the pronoia land-holding system that linked the amount of land one owned with one's ability to raise cavalry became the Ottoman timar system, and that the Ottoman land measurement the dönüm was the same as the Byzantine stremma. Stone also argues that although Sunni Islam was the state religion, the Ottoman state supported and controlled the Eastern Orthodox Church, which in return for accepting that control became the Ottoman Empire's largest land-holder. Despite the similarities, Stone argues that a crucial difference is that the land grants under the timar system were not hereditary at first. Even after they became inheritable, land ownership in the Ottoman Empire remained highly insecure, and the sultan revoked land grants whenever he wished. Stone argued this insecurity in land tenure strongly discouraged Timariots from seeking long-term development of their land, and instead led them to adopt a strategy of short-term exploitation, which had deleterious effects on the Ottoman economy.
Government
Before the reforms of the 19th and 20th centuries, the state organisation of the Ottoman Empire was a system with two main dimensions, the military administration, and the civil administration. The Sultan was in the highest position in the system. The civil system was based on local administrative units based on the region's characteristics. The state had control over the clergy. Certain pre-Islamic Turkish traditions that had survived the adoption of administrative and legal practices from Islamic Iran remained important in Ottoman administrative circles. According to Ottoman understanding, the state's primary responsibility was to defend and extend the land of the Muslims and to ensure security and harmony within its borders in the overarching context of orthodox Islamic practice and dynastic sovereignty.
The Ottoman Empire, or as a dynastic institution, the House of Osman, was unprecedented and unequalled in the Islamic world for its size and duration. In Europe, only the House of Habsburg had a similarly unbroken line of sovereigns (kings/emperors) from the same family who ruled for so long, and during the same period, between the late 13th and early 20th centuries. The Ottoman dynasty was Turkish in origin. On eleven occasions, the sultan was deposed (replaced by another sultan of the Ottoman dynasty, who were either the former sultan's brother, son or nephew) because he was perceived by his enemies as a threat to the state. There were only two attempts in Ottoman history to unseat the ruling Ottoman dynasty, both failures, which suggests a political system that for an extended period was able to manage its revolutions without unnecessary instability. As such, the last Ottoman sultan Mehmed VI (r. 1918–1922) was a direct patrilineal (male-line) descendant of the first Ottoman sultan Osman I (d. 1323/4), which was unparalleled in both Europe (e.g., the male line of the House of Habsburg became extinct in 1740) and in the Islamic world. The primary purpose of the Imperial Harem was to ensure the birth of male heirs to the Ottoman throne and secure the continuation of the direct patrilineal (male-line) power of the Ottoman sultans in the future generations.
The highest position in Islam, caliph, was claimed by the sultans starting with Selim I, which was established as the Ottoman Caliphate. The Ottoman sultan, pâdişâh or "lord of kings", served as the Empire's sole regent and was considered to be the embodiment of its government, though he did not always exercise complete control. The Imperial Harem was one of the most important powers of the Ottoman court. It was ruled by the valide sultan. On occasion, the valide sultan became involved in state politics. For a time, the women of the Harem effectively controlled the state in what was termed the "Sultanate of Women". New sultans were always chosen from the sons of the previous sultan. The strong educational system of the palace school was geared towards eliminating the unfit potential heirs and establishing support among the ruling elite for a successor. The palace schools, which also educated the future administrators of the state, were not a single track. First, the Madrasa (Medrese) was designated for the Muslims, and educated scholars and state officials according to Islamic tradition. The financial burden of the Medrese was supported by vakifs, allowing children of poor families to move to higher social levels and income. The second track was a free boarding school for the Christians, the Enderûn, which recruited 3,000 students annually from Christian boys between eight and twenty years old from one in forty families among the communities settled in Rumelia or the Balkans, a process known as Devshirme (Devşirme). The Devshirme falls within modern definitions of genocide.
Law
The Ottoman legal system accepted the religious law over its subjects. At the same time the Qanun (or Kanun), dynastic law, co-existed with religious law or Sharia. The Ottoman Empire was always organised around a system of local jurisprudence. Legal administration in the Ottoman Empire was part of a larger scheme of balancing central and local authority. Ottoman power revolved crucially around the administration of the rights to land, which gave a space for the local authority to develop the needs of the local millet. The jurisdictional complexity of the Ottoman Empire was aimed to permit the integration of culturally and religiously different groups. The Ottoman system had three court systems: one for Muslims, one for non-Muslims, involving appointed Jews and Christians ruling over their respective religious communities, and the "trade court". The entire system was regulated from above by means of the administrative Qanun, i.e., laws, a system based upon the Turkic Yassa and Töre, which were developed in the pre-Islamic era.
These court categories were not, however, wholly exclusive; for instance, the Islamic courts, which were the Empire's primary courts, could also be used to settle a trade conflict or disputes between litigants of differing religions, and Jews and Christians often went to them to obtain a more forceful ruling on an issue. The Ottoman state tended not to interfere with non-Muslim religious law systems, despite legally having a voice to do so through local governors. The Islamic Sharia law system had been developed from a combination of the Qur'an; the Hadīth, or words of Muhammad; ijmā', or consensus of the members of the Muslim community; qiyas, a system of analogical reasoning from earlier precedents; and local customs. Both systems were taught at the Empire's law schools, which were in Istanbul and Bursa.
The Ottoman Islamic legal system was set up differently from traditional European courts. Presiding over Islamic courts was a Qadi, or judge. Since the closing of the ijtihad, or 'Gate of Interpretation', Qadis throughout the Ottoman Empire focused less on legal precedent, and more with local customs and traditions in the areas that they administered. However, the Ottoman court system lacked an appellate structure, leading to jurisdictional case strategies where plaintiffs could take their disputes from one court system to another until they achieved a ruling that was in their favour.
In the late 19th century, the Ottoman legal system saw substantial reform. This process of legal modernisation began with the Edict of Gülhane of 1839. These reforms included the "fair and public trial[s] of all accused regardless of religion", the creation of a system of "separate competences, religious and civil", and the validation of testimony on non-Muslims. Specific land codes (1858), civil codes (1869–1876), and a code of civil procedure also were enacted.
Military
The first military unit of the Ottoman State was an army that was organised by Osman I from the tribesmen inhabiting the hills of western Anatolia in the late 13th century. The military system became an intricate organisation with the advance of the Empire. The Ottoman military was a complex system of recruiting and fief-holding. The main corps of the Ottoman Army included Janissary, Sipahi, Akıncı and Mehterân. The Ottoman army was once among the most advanced fighting forces in the world, being one of the first to use muskets and cannons. The Ottoman Turks began using falconets, which were short but wide cannons, during the Siege of Constantinople. The Ottoman cavalry depended on high speed and mobility rather than heavy armour, using bows and short swords on fast Turkoman and Arabian horses (progenitors of the Thoroughbred racing horse), and often applied tactics similar to those of the Mongol Empire, such as pretending to retreat while surrounding the enemy forces inside a crescent-shaped formation and then making the real attack. The Ottoman army continued to be an effective fighting force throughout the seventeenth and early eighteenth centuries, falling behind the empire's European rivals only during a long period of peace from 1740 to 1768.
The modernisation of the Ottoman Empire in the 19th century started with the military. In 1826 Sultan Mahmud II abolished the Janissary corps and established the modern Ottoman army. He named them as the Nizam-ı Cedid (New Order). The Ottoman army was also the first institution to hire foreign experts and send its officers for training in western European countries. Consequently, the Young Turks movement began when these relatively young and newly trained men returned with their education.
The Ottoman Navy vastly contributed to the expansion of the Empire's territories on the European continent. It initiated the conquest of North Africa, with the addition of Algeria and Egypt to the Ottoman Empire in 1517. Starting with the loss of Greece in 1821 and Algeria in 1830, Ottoman naval power and control over the Empire's distant overseas territories began to decline. Sultan Abdülaziz (reigned 1861–1876) attempted to reestablish a strong Ottoman navy, building the largest fleet after those of Britain and France. The shipyard at Barrow, England, built its first submarine in 1886 for the Ottoman Empire.
However, the collapsing Ottoman economy could not sustain the fleet's strength for long. Sultan Abdülhamid II distrusted the admirals who sided with the reformist Midhat Pasha and claimed that the large and expensive fleet was of no use against the Russians during the Russo-Turkish War. He locked most of the fleet inside the Golden Horn, where the ships decayed for the next 30 years. Following the Young Turk Revolution in 1908, the Committee of Union and Progress sought to develop a strong Ottoman naval force. The Ottoman Navy Foundation was established in 1910 to buy new ships through public donations.
Administrative divisions
The Ottoman Empire was first subdivided into provinces, in the sense of fixed territorial units with governors appointed by the sultan, in the late 14th century.
The eyalet (also pashalik or beylerbeylik) was the territory of office of a beylerbey ("lord of lords" or governor), and was further subdivided into Sanjaks.
The vilayets were introduced with the promulgation of the "Vilayet Law" (Teskil-i Vilayet Nizamnamesi) in 1864, as part of the Tanzimat reforms. Unlike the previous eyalet system, the 1864 law established a hierarchy of administrative units: the vilayet, liva/sanjak/mutasarrifate, kaza and village council, to which the 1871 Vilayet Law added the nahiye.
Economy
The Ottoman government deliberately pursued a policy for the development of Bursa, Edirne, and Istanbul, successive Ottoman capitals, into major commercial and industrial centres, considering that merchants and artisans were indispensable in creating a new metropolis. To this end, Mehmed and his successor Bayezid, also encouraged and welcomed migration of the Jews from different parts of Europe, who were settled in Istanbul and other port cities like Salonica. In many places in Europe, Jews were suffering persecution at the hands of their Christian counterparts, such as in Spain, after the conclusion of the Reconquista. The tolerance displayed by the Turks was welcomed by the immigrants.
The Ottoman economic mind was closely related to the basic concepts of state and society in the Middle East in which the ultimate goal of a state was consolidation and extension of the ruler's power, and the way to reach it was to get rich resources of revenues by making the productive classes prosperous. The ultimate aim was to increase the state revenues without damaging the prosperity of subjects to prevent the emergence of social disorder and to keep the traditional organisation of the society intact. The Ottoman economy greatly expanded during the early modern period, with particularly high growth rates during the first half of the 18th century. The empire's annual income quadrupled between 1523 and 1748, adjusted for inflation.
The organisation of the treasury and chancery were developed under the Ottoman Empire more than any other Islamic government and, until the 17th century, they were the leading organisation among all their contemporaries. This organisation developed a scribal bureaucracy (known as "men of the pen") as a distinct group, partly highly trained ulama, which developed into a professional body. The effectiveness of this professional financial body stands behind the success of many great Ottoman statesmen.
Modern Ottoman studies indicate that the change in relations between the Ottoman Turks and central Europe was caused by the opening of the new sea routes. It is possible to see the decline in the significance of the land routes to the East as Western Europe opened the ocean routes that bypassed the Middle East and the Mediterranean as parallel to the decline of the Ottoman Empire itself. The Anglo-Ottoman Treaty, also known as the Treaty of Balta Liman that opened the Ottoman markets directly to English and French competitors, can be seen as one of the staging posts along with this development.
Demographics
A population estimate for the empire of 11,692,480 for the 1520–1535 period was obtained by counting the households in Ottoman tithe registers, and multiplying this number by 5. For unclear reasons, the population in the 18th century was lower than that in the 16th century. An estimate of 7,230,660 for the first census held in 1831 is considered a serious undercount, as this census was meant only to register possible conscripts.
Censuses of Ottoman territories only began in the early 19th century. Figures from 1831 onwards are available as official census results, but the censuses did not cover the whole population. For example, the 1831 census only counted men and did not cover the whole empire. For earlier periods estimates of size and distribution of the population are based on observed demographic patterns.
However, it began to rise to reach 25–32 million by 1800, with around 10 million in the European provinces (primarily in the Balkans), 11 million in the Asiatic provinces, and around 3 million in the African provinces. Population densities were higher in the European provinces, double those in Anatolia, which in turn were triple the population densities of Iraq and Syria and five times the population density of Arabia.
Towards the end of the empire's existence life expectancy was 49 years, compared to the mid-twenties in Serbia at the beginning of the 19th century. Epidemic diseases and famine caused major disruption and demographic changes. In 1785 around one-sixth of the Egyptian population died from the plague and Aleppo saw its population reduced by twenty percent in the 18th century. Six famines hit Egypt alone between 1687 and 1731 and the last famine to hit Anatolia was four decades later. The 1812–1819 Ottoman plague epidemic would cost the lives of at least 300,000 individuals.
The rise of port cities saw the clustering of populations caused by the development of steamships and railroads. Urbanisation increased from 1700 to 1922, with towns and cities growing. Improvements in health and sanitation made them more attractive to live and work in. Port cities like Salonica, in Greece, saw its population rise from 55,000 in 1800 to 160,000 in 1912 and İzmir which had a population of 150,000 in 1800 grew to 300,000 by 1914. Some regions conversely had population falls—Belgrade saw its population drop from 25,000 to 8,000 mainly due to political strife.
Language
Ottoman Turkish was the official language of the Empire. It was an Oghuz Turkic language highly influenced by Persian and Arabic, though lower registries spoken by the common people had fewer influences from other languages compared to higher varieties used by upper classes and governmental authorities. Turkish, in its Ottoman variation, was a language of military and administration since the nascent days of the Ottomans. The Ottoman constitution of 1876 did officially cement the official imperial status of Turkish.
The Ottomans had several influential languages: Turkish, spoken by the majority of the people in Anatolia and by the majority of Muslims of the Balkans except some regions such as Albania, Bosnia and the Megleno-Romanian-inhabited Nânti; Persian, only spoken by the educated; Arabic, spoken mainly in Egypt, the Levant, Arabia, Iraq, North Africa, Kuwait and parts of the Horn of Africa and Berber in North Africa. In the last two centuries, usage of these became limited, though, and specific: Persian served mainly as a literary language for the educated, while Arabic was used for Islamic prayers. In the post-Tanzimat period French became the common Western language among the educated.
Because of a low literacy rate among the public (about 2–3% until the early 19th century and just about 15% at the end of the 19th century), ordinary people had to hire scribes as "special request-writers" (arzuhâlcis) to be able to communicate with the government. Some ethnic groups continued to speak within their families and neighbourhoods (mahalles) with their own languages, though many non-Muslim minorities such as Greeks and Armenians only spoke Turkish. In villages where two or more populations lived together, the inhabitants often spoke each other's language. In cosmopolitan cities, people often spoke their family languages; in some cities, many of those who were not ethnic Turks spoke Turkish as a second language. However, not all cities used Turkish as a lingua franca.
Religion
Sunni Islam was the prevailing Dīn (customs, legal traditions, and religion) of the Ottoman Empire; the official Madh'hab (school of Islamic jurisprudence) was Hanafi. From the early 16th century until the early 20th century, the Ottoman sultan also served as the caliph, or politico-religious leader, of the Muslim world. Most of the Ottoman Sultans adhered to Sufism and followed Sufi orders, and believed Sufism was the correct way to reach God.
Non-Muslims, particularly Christians and Jews, were present throughout the empire's history. The Ottoman imperial system was charactised by an intricate combination of official Muslim hegemony over non-Muslims and a wide degree of religious tolerance. While religious minorities were never equal under the law, they were granted recognition, protection, and limited freedoms under both Islamic and Ottoman tradition.
Until the second half of the 15th century, the majority of Ottoman subjects were Christian. Non-Muslims remained a significant and economically influential minority, albeit declining significantly by the 19th century, due largely to migration and secession. The proportion of Muslims amounted to 60% in the 1820s, gradually increasing to 69% in the 1870s and 76% in the 1890s. By 1914, less than a fifth of the empire's population (19.1%) was non-Muslim, mostly made up of Jews and Christian Greeks, Assyrians, and Armenians.
Turkic peoples practiced a form of shamanism before adopting Islam. The Muslim conquest of Transoxiana under the Abbasids facilitated the spread of Islam into the Turkic heartland of Central Asia. Many Turkic tribes—including the Oghuz Turks, who were the ancestors of both the Seljuks and the Ottomans—gradually converted to Islam and brought religion to Anatolia through their migrations beginning in the 11th century. From its founding, the Ottoman Empire officially supported the Maturidi school of Islamic theology, which emphasised human reason, rationality, the pursuit of science and philosophy (falsafa). The Ottomans were among the earliest and most enthusiastic adopters of the Hanafi school of Islamic jurisprudence, which was comparatively more flexible and discretionary in its rulings.
The Ottoman Empire had a wide variety of Islamic sects, including Druze, Ismailis, Alevis, and Alawites. Sufism, a diverse body of Islamic mysticism, found fertile ground in Ottoman lands; many Sufi religious orders (tariqa), such as the Bektashi and Mevlevi, were either established, or saw significant growth, throughout the empire's history. However, some heterodox Muslim groups were viewed as heretical and even ranked below Jews and Christians in terms of legal protection; Druze were frequent targets of persecution, with Ottoman authorities often citing the controversial rulings of Ibn Taymiyya, a member of the conservative Hanbali school. In 1514, Sultan Selim I ordered the massacre of 40,000 Anatolian Alevis (Qizilbash), whom he considered a fifth column for the rival Safavid Empire.
Social-political-religious structure
Beginning in the early 19th century, society, government, and religion were interrelated in a complex, overlapping way that was deemed inefficient by Atatürk, who systematically dismantled it after 1922. In Constantinople, the Sultan ruled two distinct domains: the secular government and the religious hierarchy. Religious officials formed the Ulama, who had control of religious teachings and theology, and also the Empire's judicial system, giving them a major voice in day-to-day affairs in communities across the Empire (but not including the non-Muslim millets). They were powerful enough to reject the military reforms proposed by Sultan Selim III. His successor Sultan Mahmud II (r. 1808–1839) first won ulama approval before proposing similar reforms. The secularisation programme brought by Atatürk ended the ulema and their institutions. The caliphate was abolished, madrasas were closed down, and the sharia courts were abolished. He replaced the Arabic alphabet with Latin letters, ended the religious school system, and gave women some political rights. Many rural traditionalists never accepted this secularisation, and by the 1990s they were reasserting a demand for a larger role for Islam.
The Janissaries were a highly formidable military unit in the early years, but as Western Europe modernised its military organisation technology, the Janissaries became a reactionary force that resisted all change. Steadily the Ottoman military power became outdated, but when the Janissaries felt their privileges were being threatened, or outsiders wanted to modernise them, or they might be superseded by the cavalrymen, they rose in rebellion. The rebellions were highly violent on both sides, but by the time the Janissaries were suppressed, it was far too late for Ottoman military power to catch up with the West. The political system was transformed by the destruction of the Janissaries, a powerful military/governmental/police force, which revolted in the Auspicious Incident of 1826. Sultan Mahmud II crushed the revolt, executed the leaders and disbanded the large organisation. That set the stage for a slow process of modernisation of government functions, as the government sought, with mixed success, to adopt the main elements of Western bureaucracy and military technology.
The Janissaries had been recruited from Christians and other minorities; their abolition enabled the emergence of a Turkish elite to control the Ottoman Empire. A large number of ethnic and religious minorities were tolerated in their own separate segregated domains called millets. They were primarily Greek, Armenian, or Jewish. In each locality, they governed themselves, spoke their own language, ran their own schools, cultural and religious institutions, and paid somewhat higher taxes. They had no power outside the millet. The Imperial government protected them and prevented major violent clashes between ethnic groups.
Culture
The Ottomans absorbed some of the traditions, art, and institutions of cultures in the regions they conquered and added new dimensions to them. Numerous traditions and cultural traits of previous empires (in fields such as architecture, cuisine, music, leisure, and government) were adopted by the Ottoman Turks, who developed them into new forms, resulting in a new and distinctively Ottoman cultural identity. Although the predominant literary language of the Ottoman Empire was Turkish, Persian was the preferred vehicle for the projection of an imperial image.
Slavery was part of Ottoman society, with most slaves employed as domestic servants or in the case of female slaves as concubines (sexual slaves).
Agricultural slavery, such as that in the Americas, was relatively rare.
The child of a slave was born a slave, unless the male slave owner acknowledged the child of his female slave as his, in which case the child would be automatically free by law.
Female slaves were still sold in the Empire as late as 1908.
During the 19th century the Empire came under pressure from Western European countries to outlaw the practice. Policies developed by various sultans throughout the 19th century attempted to curtail the Ottoman slave trade but slavery had centuries of religious backing and sanction and so was never abolished in the Empire.
Ottomans adopted Persian bureaucratic traditions and culture. The sultans also made an important contribution in the development of Persian literature.
Language was not an obvious sign of group connection and identity in the 16th century among the rulers of the Ottoman Empire, Safavid Iran and Abu'l-Khayrid Shibanids of Central Asia. Hence the ruling classes of all three polities were bilingual in varieties of Persian and Turkic. But in the century's final quarter, linguistic adjustments occurred in the Ottoman and Safavid realms defined by a new rigidity that favoured Ottoman Turkish and Persian, respectively.
Education
In the Ottoman Empire, each millet established a schooling system serving its members. Education was therefore largely divided on ethnic and religious lines: few non-Muslims attended schools for Muslim students, and vice versa. Most institutions that served all ethnic and religious groups taught in French or other languages.
Several "foreign schools" (Frerler mektebleri) operated by religious clergy primarily served Christians, although some Muslim students attended. Garnett described the schools for Christians and Jews as "organised upon European models", with "voluntary contributions" supporting their operation and most of them "well attended" and with "a high standard of education".
Literature
The two primary streams of Ottoman written literature are poetry and prose. Poetry was by far the dominant stream. The earliest work of Ottoman historiography for example, the İskendernâme, was composed by the poet Taceddin Ahmedi. Until the 19th century, Ottoman prose did not contain any examples of fiction: there were no counterparts to, for instance, the European romance, short story, or novel. Analog genres did exist, though, in both Turkish folk literature and in Divan poetry.
Ottoman Divan poetry was a highly ritualised and symbolic art form. From the Persian poetry that largely inspired it, it inherited a wealth of symbols whose meanings and interrelationships—both of similitude (مراعات نظير mura'ât-i nazîr / تناسب tenâsüb) and opposition (تضاد tezâd) were more or less prescribed. Divan poetry was composed through the constant juxtaposition of many such images within a strict metrical framework, allowing numerous potential meanings to emerge. The vast majority of Divan poetry was lyric in nature: either gazels (which make up the greatest part of the repertoire of the tradition), or kasîdes. But there were other common genres, especially the mesnevî, a kind of verse romance and thus a variety of narrative poetry; the two most notable examples of this form are the Leyli and Majnun of Fuzuli and the Hüsn ü Aşk of Şeyh Gâlib. The Seyahatnâme of Evliya Çelebi (1611–1682) is an outstanding example of travel literature.
Until the 19th century, Ottoman prose did not develop to the extent that contemporary Divan poetry did. A large part of the reason was that much prose was expected to adhere to the rules of sec (سجع, also transliterated as seci), or rhymed prose, a type of writing descended from the Arabic saj' that prescribed that between each adjective and noun in a string of words, such as a sentence, there must be a rhyme. Nevertheless, there was a tradition of prose in the literature of the time, though it was exclusively nonfictional. One apparent exception was Muhayyelât (Fancies) by Giritli Ali Aziz Efendi, a collection of stories of the fantastic written in 1796, though not published until 1867. The first novel published in the Ottoman Empire was Vartan Pasha's 1851 The Story of Akabi (Turkish: Akabi Hikyayesi). It was written in Turkish but with Armenian script.
Due to historically close ties with France, French literature constituted the major Western influence on Ottoman literature in the latter half of the 19th century. As a result, many of the same movements prevalent in France during this period had Ottoman equivalents; in the developing Ottoman prose tradition, for instance, the influence of Romanticism can be seen during the Tanzimat period, and that of the Realist and Naturalist movements in subsequent periods; in the poetic tradition, on the other hand, the influence of the Symbolist and Parnassian movements was paramount.
Media
The media of the Ottoman Empire was diverse, with newspapers and journals published in languages including French, Greek, and German. Many of these publications were centred in Constantinople, but there were also French-language newspapers produced in Beirut, Salonika, and Smyrna. Non-Muslim ethnic minorities in the empire used French as a lingua franca and used French-language publications, while some provincial newspapers were published in Arabic. The use of French in the media persisted until the end of the empire in 1923 and for a few years thereafter in the Republic of Turkey.
Architecture
The architecture of the empire developed from earlier Seljuk Turkish architecture, with influences from Byzantine and Iranian architecture and other architectural traditions in the Middle East. Early Ottoman architecture experimented with multiple building types over the course of the 13th to 15th centuries, progressively evolving into the classical Ottoman style of the 16th and 17th centuries, which was also strongly influenced by the Hagia Sophia. The most important architect of the Classical period is Mimar Sinan, whose major works include the Şehzade Mosque, Süleymaniye Mosque, and Selimiye Mosque. The second half of the 16th century also saw the apogee of some types of decoration, most notably in the production of Iznik tiles.
Beginning in the 18th century, Ottoman architecture was opened to external influences, particularly from Baroque architecture in Western Europe, which eventually gave rise to the Ottoman Baroque style that emerged in the 1740s. The Nuruosmaniye Mosque is one of the most important examples from this period. During the 19th century, influences from Western Europe became more prominent, brought in by architects such as those from the Balyan family. Empire style and Neoclassical motifs were introduced and a trend towards eclecticism was evident in many types of buildings, such as the Dolmabaçe Palace. The last decades of the Ottoman Empire also saw the development of a new architectural style called neo-Ottoman or Ottoman revivalism, also known as the First National Architectural Movement, by architects such as Mimar Kemaleddin and Vedat Tek.
Ottoman dynastic patronage was concentrated in the historic capitals of Bursa, Edirne, and Istanbul (Constantinople), as well as in several other important administrative centres such as Amasya and Manisa. It was in these centres that most important developments in Ottoman architecture occurred and that the most monumental Ottoman architecture can be found. Major religious monuments were typically architectural complexes, known as a külliye, that had multiple components providing different services or amenities. In addition to a mosque, these could include a madrasa, a hammam, an imaret, a sebil, a market, a caravanserai, a primary school, or others. These complexes were governed and managed with the help of a vakıf agreement (Arabic waqf). Ottoman constructions were still abundant in Anatolia and in the Balkans (Rumelia), but in the more distant Middle Eastern and North African provinces older Islamic architectural styles continued to hold strong influence and were sometimes blended with Ottoman styles.
Decorative arts
The tradition of Ottoman miniatures, painted to illustrate manuscripts or used in dedicated albums, was heavily influenced by the Persian art form, though it also included elements of the Byzantine tradition of illumination and painting. A Greek academy of painters, the Nakkashane-i-Rum, was established in the Topkapi Palace in the 15th century, while early in the following century a similar Persian academy, the Nakkashane-i-Irani, was added. Surname-i Hümayun (Imperial Festival Books) were albums that commemorated celebrations in the Ottoman Empire in pictorial and textual detail.
Ottoman illumination covers non-figurative painted or drawn decorative art in books or on sheets in muraqqa or albums, as opposed to the figurative images of the Ottoman miniature. It was a part of the Ottoman Book Arts together with the Ottoman miniature (taswir), calligraphy (hat), Islamic calligraphy, bookbinding (cilt) and paper marbling (ebru). In the Ottoman Empire, illuminated and illustrated manuscripts were commissioned by the Sultan or the administrators of the court. In Topkapi Palace, these manuscripts were created by the artists working in Nakkashane, the atelier of the miniature and illumination artists. Both religious and non-religious books could be illuminated. Also, sheets for albums levha consisted of illuminated calligraphy (hat) of tughra, religious texts, verses from poems or proverbs, and purely decorative drawings.
The art of carpet weaving was particularly significant in the Ottoman Empire, carpets having an immense importance both as decorative furnishings, rich in religious and other symbolism and as a practical consideration, as it was customary to remove one's shoes in living quarters. The weaving of such carpets originated in the nomadic cultures of central Asia (carpets being an easily transportable form of furnishing), and eventually spread to the settled societies of Anatolia. Turks used carpets, rugs, and kilims not just on the floors of a room but also as a hanging on walls and doorways, where they provided additional insulation. They were also commonly donated to mosques, which often amassed large collections of them.
Music and performing arts
Ottoman classical music was an important part of the education of the Ottoman elite. A number of the Ottoman sultans have accomplished musicians and composers themselves, such as Selim III, whose compositions are often still performed today. Ottoman classical music arose largely from a confluence of Byzantine music, Armenian music, Arabic music, and Persian music. Compositionally, it is organised around rhythmic units called usul, which are somewhat similar to metre in Western music, and melodic units called makam, which bear some resemblance to Western musical modes.
The instruments used are a mixture of Anatolian and Central Asian instruments (the saz, the bağlama, the kemence), other Middle Eastern instruments (the ud, the tanbur, the kanun, the ney), and—later in the tradition—Western instruments (the violin and the piano). Because of a geographic and cultural divide between the capital and other areas, two broadly distinct styles of music arose in the Ottoman Empire: Ottoman classical music and folk music. In the provinces, several different kinds of folk music were created. The most dominant regions with their distinguished musical styles are Balkan-Thracian Türküs, North-Eastern (Laz) Türküs, Aegean Türküs, Central Anatolian Türküs, Eastern Anatolian Türküs, and Caucasian Türküs. Some of the distinctive styles were: Janissary music, Roma music, Belly dance, Turkish folk music.
The traditional shadow play called Karagöz and Hacivat was widespread throughout the Ottoman Empire and featured characters representing all of the major ethnic and social groups in that culture. It was performed by a single puppet master, who voiced all of the characters, and accompanied by tambourine (def). Its origins are obscure, deriving perhaps from an older Egyptian tradition, or possibly from an Asian source.
Cuisine
Ottoman cuisine is the cuisine of the capital, Constantinople (Istanbul), and the regional capital cities, where the melting pot of cultures created a common cuisine that most of the population regardless of ethnicity shared. This diverse cuisine was honed in the Imperial Palace's kitchens by chefs brought from certain parts of the Empire to create and experiment with different ingredients. The creations of the Ottoman Palace's kitchens filtered to the population, for instance through Ramadan events, and through the cooking at the Yalıs of the Pashas, and from there on spread to the rest of the population.
Much of the cuisine of former Ottoman territories today is descended from a shared Ottoman cuisine, especially Turkish, and including Greek, Balkan, Armenian, and Middle Eastern cuisines.
Sports
The main sports Ottomans were engaged in were Turkish wrestling, hunting, Turkish archery, horseback riding, equestrian javelin throw, arm wrestling, and swimming. European model sports clubs were formed with the spreading popularity of football matches in 19th-century Constantinople. The leading clubs, according to timeline, were Beşiktaş Gymnastics Club (1903), Galatasaray Sports Club (1905), Fenerbahçe Sports Club (1907), MKE Ankaragücü (formerly Turan Sanatkarangücü) (1910) in Constantinople. Football clubs were formed in other provinces too, such as Karşıyaka Sports Club (1912), Altay Sports Club (1914) and Turkish Fatherland Football Club (later Ülküspor) (1914) of İzmir.
Science and technology
Over the course of Ottoman history, the Ottomans managed to build a large collection of libraries complete with translations of books from other cultures, as well as original manuscripts. A great part of this desire for local and foreign manuscripts arose in the 15th century. Sultan Mehmet II ordered Georgios Amiroutzes, a Greek scholar from Trabzon, to translate and make available to Ottoman educational institutions the geography book of Ptolemy. Another example is Ali Qushji – an astronomer, mathematician and physicist originally from Samarkand – who became a professor in two madrasas and influenced Ottoman circles as a result of his writings and the activities of his students, even though he only spent two or three years in Constantinople before his death.
Taqi al-Din built the Constantinople observatory of Taqi ad-Din in 1577, where he carried out observations until 1580. He calculated the eccentricity of the Sun's orbit and the annual motion of the apogee. However, the observatory's primary purpose was almost certainly astrological rather than astronomical, leading to its destruction in 1580 due to the rise of a clerical faction that opposed its use for that purpose. He also experimented with steam power in Ottoman Egypt in 1551, when he described a steam jack driven by a rudimentary steam turbine.
Şerafeddin Sabuncuoğlu was the author of the first surgical atlas and the last major medical encyclopaedia from the Islamic world. The Ottoman Empire is credited with the invention of several surgical instruments in use such as forceps, catheters, scalpels and lancets as well as pincers.
In the early 19th century, Egypt under Muhammad Ali began using steam engines for industrial manufacturing, with industries such as ironworks, textile manufacturing, paper mills and hulling mills moving towards steam power. Economic historian Jean Batou argues that the necessary economic conditions existed in Egypt for the adoption of oil as a potential energy source for its steam engines later in the 19th century.
