Geography
In the most common historical sense, 'Syria' refers to the entire northern Levant, including Alexandretta and the Ancient City of Antioch or in an extended sense the entire Levant as far south as Roman Egypt, including Mesopotamia. The area of "Greater Syria" (Arabic: سُوْرِيَّة ٱلْكُبْرَىٰ, Sūrīyah al-Kubrā); also called "Natural Syria" (Arabic: سُوْرِيَّة ٱلطَّبِيْعِيَّة, Sūrīyah aṭ-Ṭabīʿīyah) or "Northern Land" (Arabic: بِلَاد ٱلشَّام, Bilād ash-Shām), extends roughly over the Bilad al-Sham province of the medieval Arab caliphates, encompassing the Eastern Mediterranean (or Levant) and Western Mesopotamia. The term “Natural Syria” has historically been used to describe a geographic concept of the region that predates modern political borders. It defines the region as a natural whole. However, the boundaries of Bilad al-Sham/Greater Syria were not consistently defined across historical periods and often shifted depending on administrative, geographic, or cultural usage. In the 20th century, this idea also entered cultural and political discourse to preserve regional unity conceptually and frame the newly imposed divisions of the French and British mandates as unnatural and artificial.
The Muslim conquest of the Levant in the seventh century gave rise to this province, which encompassed much of the region of Syria, and came to largely overlap with this concept. Although it was at times organized as a province under larger empires, Bilad al-Sham was only intermittently administered as a single unified territorial unit. Other sources indicate that the term Greater Syria was coined during Ottoman rule, after 1516, to designate the approximate area included in present-day Israel, Palestine, Syria, Jordan, Lebanon.
The uncertainty in the definition of the extent of "Syria" is aggravated by the etymological confusion of the similar-sounding names Syria and Assyria. The question of the etymological identity of the two names remains open today. Regardless of etymology, both were thought of as interchangeable around the time of Herodotus. However, by the time of the Roman Empire, 'Syria' and 'Assyria' began to refer to two separate entities, Roman Syria and Roman Assyria.
Killebrew and Steiner, treating the Levant as the Syrian region, gave the boundaries of the region as such: the Mediterranean Sea to the west, the Arabian Desert to the south, Mesopotamia to the east, and the Taurus Mountains of Anatolia to the north. The Muslim geographer Muhammad al-Idrisi visited the region in 1150 and assigned the northern regions of Bilad al-Sham as the following:
In the Levantine sea are two islands: Rhodes and Cyprus; and in Levantine lands: Antarsus, Laodice, Antioch, Mopsuhestia, Adana, Anazarbus, Tarsus, Circesium, Ḥamrtash, Antalya, al-Batira, al-Mira, Macri, Astroboli; and in the interior lands: Apamea, Salamiya, Qinnasrin, al-Castel, Aleppo, Resafa, Raqqa, Rafeqa, al-Jisr, Manbij, Mar'ash, Saruj, Ḥarran, Edessa, Al-Ḥadath, Samosata, Malatiya, Ḥusn Mansur, Zabatra, Jersoon, al-Leen, al-Bedandour, Cirra and Touleb.
For Pliny the Elder and Pomponius Mela, Syria covered the entire Fertile Crescent. In Late Antiquity, "Syria" meant a region located to the east of the Mediterranean Sea, west of the Euphrates River, north of the Arabian Desert, and south of the Taurus Mountains, thereby including modern Syria, Lebanon, Jordan, Israel, the State of Palestine, and the Hatay Province and the western half of the Southeastern Anatolia Region of southern Turkey. This late definition is equivalent to the region known in Classical Arabic by the name ash-Shām (ٱلشَّام /ʔaʃ-ʃaːm/), which means the north [country] (from the root šʔm شَأْم "left, north"). After the Islamic conquest of Byzantine Syria in the seventh century, the name Syria fell out of primary use in the region itself, being superseded by the Arabic equivalent Bilād ash-Shām ("Northern Land'"), but survived in its original sense in Byzantine and Western European usage, and in Syriac Christian literature. In the 19th century, the name Syria was revived in its modern Arabic form to denote the whole of Bilad al-Sham, either as Suriyah or the modern form Suriyya, which eventually replaced the Arabic name of Bilad al-Sham. After World War I, the name 'Syria' was applied to the French Mandate for Syria and the Lebanon, and the contemporaneous but short-lived Arab Kingdom of Syria. Historically, no single city maintained long-term dominance over the entire region, and Bilad al-Sham developed as a decentralized network of multiple urban centers rather than around one permanent political or economic capital.
The region has multiple rivers, including the Yarmuk, Khabur, Queiq, Daysan, Balikh, Jordan, Orontes, Litani, and Barada. As well as multiple bodies of water, including the Sea of Galilee, Lake Assad, Lake Qattinah, Dead Sea, Lake Homs, Sabkhat al-Jabbul, Sabkhat al-Mouh, and Sabkhat al-Mouhajjarah. Mountain chains include the Lebanon, Taurus, anti-Lebanon, Nusayri, Carmel, Nur, and Jordanian highlands.
Today, the largest metropolitan areas in the region are Amman, Tel Aviv, Damascus, Beirut, Aleppo and Gaza City.
