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.
Baden Revolution
Their high points were the Hecker uprising in April 1848, the Struve Putsch of September 1848 and the rebellion as part of the Imperial Constitution campaign ("Reichsverfassungskampagne") in May 1849 which assumed civil war-like proportions and was also known as the May Revolution. The rebellion ended on 23 July 1849 with the military defeat of the last revolt and the capture of Rastatt Fortress by federal troops under Prussian leadership.
