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.
May Revolution
At dawn on May 23, the Cabildo informed the population that the Viceroy would end his mandate. The highest authority would be transferred temporarily to the Cabildo until the appointment of a governing junta. Notices were placed at various points throughout the city, which announced the imminent creation of a junta and the summoning of representatives from the provinces. The notices also called for the public to refrain from actions contrary to public policy.
