Charles IV (Spanish: Carlos Antonio Pascual Francisco Javier Juan Nepomuceno José Januario Serafín Diego de Borbón y Sajonia; 11 November 1748 – 20 January 1819) was King of Spain and ruler of the Spanish Empire from 1788 to 1808.
The Spain inherited by Charles IV gave few indications of instability, but during his reign, Spain entered a series of disadvantageous alliances and his regime constantly sought cash to deal with the exigencies of war. He detested his son and heir Ferdinand, who led the unsuccessful El Escorial Conspiracy and later forced Charles's abdication after the Tumult of Aranjuez in March 1808, along with ousting Charles's widely hated first minister Manuel Godoy. Summoned to Bayonne by Napoleon Bonaparte, who forced Ferdinand VII to abdicate, Charles IV also abdicated, paving the way for Napoleon to place his elder brother Joseph Bonaparte on the throne of Spain. The reign of Charles IV turned out to be a major negative turning point in Spanish history.

Early life
Charles was the second son of Charles III and his wife, Maria Amalia of Saxony. He was born in Naples (11 November 1748), while his father was King of Naples and Sicily. His elder brother Don Felipe was passed over for both thrones, due to his learning disabilities and epilepsy. In Naples and Sicily, Charles was referred to as the Prince of Taranto. He was called El Cazador (meaning "the Hunter"), due to his preference for sport and hunting, rather than dealing with affairs of state. Charles is considered by historian Stanley G. Payne as "good-hearted but weak and simple-minded".
Reign
In 1788, Charles III died; Charles IV succeeded to the throne and ruled for the next two decades. Even though he had a profound belief in the sanctity of the monarchy and kept up the appearance of an absolute, powerful king, Charles never took more than a passive part in his own government. The affairs of government were left to his wife, Maria Luisa, and the man he appointed first minister, Manuel de Godoy. Charles occupied himself with hunting in the period that saw the outbreak of the French Revolution, the executions of his Bourbon relative Louis XVI of France and his queen, Marie Antoinette, and the rise of Napoleon Bonaparte. Ideas of the Age of Enlightenment had come to Spain with the accession of the first Spanish Bourbon, Philip V. Charles' father, Charles III, had pursued an active policy of reform that sought to reinvigorate Spain politically and economically and make the Spanish Empire more closely an appendage of the metropole. Charles III was an active, working monarch with experienced first ministers to help reach decisions. Charles IV, by contrast, was a do-nothing king, with a domineering wife and an inexperienced but ambitious first minister, Godoy. The combination of a king not up to the task of governance, the queen widely perceived to take lovers (including Godoy) and the first minister with an agenda of his own earned the monarchy increased alienation from its subjects.
Upon ascending to the throne, Charles IV intended to maintain the policies of his father and, accordingly, retained his prime minister, the Count of Floridablanca. Floridablanca avoided war with Great Britain in the Nootka Sound crisis, where a minor trade and navigation dispute off the west coast of Vancouver Island in 1789 could have blown up into a major conflict. Spain could have drawn on its French ally in support against Britain but they refused. In a humiliating move, Floridablanca had no choice but to capitulate to British terms and thereby negotiated with them. In 1792, political and personal enemies ousted Floridablanca from office, replacing him with the Count of Aranda. However, in the wake of the war against Republican France, the liberal-leaning Count of Aranda was himself replaced by Manuel de Godoy, a favorite of the Queen and widely believed to be her lover, who enjoyed the lasting favor of the King.
Under Charles IV, scientific expeditions continued to be sent by the crown, some of which were initially authorized by Charles III. The Royal Botanical Expedition to New Granada (1783–1816), and the Royal Botanical Expedition to New Spain (1787–1803), were funded by the crown. The Malaspina Expedition (1789–94) was an important scientific expedition headed by Spanish naval commander Alejandro Malaspina, with naturalists and botanical illustrators gathering information for the Spanish crown. In 1803, he authorized the Balmis Expedition, aimed at vaccinating Spain's overseas territories against smallpox. In 1799, Charles IV authorized Prussian aristocrat and scientist Alexander von Humboldt to travel freely in Spanish America, with royal officials encouraged to aid him in his investigation of key areas of Spain's empire. Humboldt's Political Essay on the Kingdom of New Spain was a key publication from his five-year travels.
Abdications of Bayonne
Riots, and a popular revolt at the winter palace Aranjuez, in 1808 forced the king to abdicate on 19 March, in favor of his son. Ferdinand took the throne as Ferdinand VII, but was mistrusted by Napoleon, who had 100,000 soldiers stationed in Spain by that time due to the ongoing War of the Third Coalition.
The ousted king, having appealed to Napoleon for help in regaining his throne, was summoned before Napoleon in Bayonne, along with his son, in April 1808. Napoleon forced both Charles and his son to abdicate, declared the Bourbon dynasty of Spain deposed, and installed his brother, Joseph Bonaparte, as King Joseph I of Spain, which began the Peninsular War.
Later life and death
Following Napoleon's deposing of the Bourbon dynasty, the ex-King, his wife, and former prime minister Godoy were held captive in France first at the château de Compiègne and three years in Marseille (where a neighborhood was named after him). After the collapse of the regime installed by Napoleon, Ferdinand VII was restored to the throne. The former Charles IV drifted about Europe until 1812, when he finally settled in Rome, in the Palazzo Barberini. His wife died on 2 January 1819, followed shortly by Charles, who died on 19 January of the same year. At the time of his death Charles was visiting his brother Ferdinand I of the Two Sicilies in Naples. Sir Francis Ronalds included a detailed description of the funeral in his travel journal.
Character
Well-meaning and pious, Charles IV floundered in a series of international crises beyond his capacity to handle. He was said to be 'despotic, sluggish and stupid'. He was also noted as a former wrestler who spent many a time hunting. He was painted by Francisco Goya in a number of official court portraits, which numerous art critics have seen as satires on the King's stout vacuity.
Marriage and children
Charles IV married his first cousin Maria Louisa, the daughter of Philip, Duke of Parma, in 1765. The couple had fourteen children, seven of whom survived into adulthood:
