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.
2012 May Day protests
Over the decades, the May Day protests and demonstrations have expanded globally and internationally to other countries including Canada, Indonesia, and Taiwan. The protests are also a part of the Occupy Movement, a movement dedicated to protesting against capitalism and the corruption of corporations and to finding solidarity within labor unions and other activist groups.
