May Revolution
The mutiny of Aranjuez in 1808 led King Charles IV of Spain to abdicate in favor of his son, Ferdinand VII. Charles IV requested that Napoleon restore him to the throne; instead, Napoleon crowned his own brother, Joseph Bonaparte, as the new Spanish King. These events are known as the Abdications of Bayonne. Joseph's coronation was met with severe resistance in Spain, which started the Peninsular War, and the Supreme Central Junta took power in the name of the absent king. This also led to Spain switching allegiances from France to Britain. France eventually invaded Sevilla, and a Council of Regency based in Cadiz replaced the disbanded Supreme Central Junta.
Historiography of the May Revolution
Cornelio Saavedra spoke about the issue privately with Juan José Viamonte in a letter from 27 June 1811, addressing topics such as a known display of independentism by Máximo de Zamudio. This letter was subsequently rescued. In it, he explicitly mentioned the situation as a deception to avoid England from declaring war on them.
