Charles IV, king of Spain, abdicates after riots and a popular revolt at the winter palace Aranjuez. His son, Ferdinand VII, takes the throne.

Charles IV was King of Spain and ruler of the Spanish Empire from 1788 to 1808.

The Tumult of Aranjuez, also known as the Mutiny of Aranjuez, was an uprising led against King Charles IV that took place in the town of Aranjuez, Spain, on 17–19 March 1808. The event, which is celebrated annually in the first week of September, commemorates the fall of the monarch and the subsequent accession of his son Ferdinand VII. It is celebrated in September rather than in March as the revived celebrations in Aranjuez that began in 1988 were added on top of pre-existing September festivals.

Ferdinand VII was King of Spain during the early 19th century. He reigned briefly in 1808 and then again from 1813 to his death in 1833. Before 1813 he was known as el Deseado, and after, as el Rey Felón.

March 19 is the 78th day of the year in the Gregorian calendar; 287 days remain until the end of the year.
