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.
Causes of the May Revolution
The ideals of the French Revolution of 1789 were spreading as well. During the Revolution, centuries of monarchy were ended with the overthrow and execution of the King Louis XVI and Queen Marie Antoinette, and the removal of the privileges of the nobility. The Declaration of the Rights of Man and of the Citizen was highly popular among the young Criollos. The French Revolution also boosted liberal ideals in political and economic fields. Some of the most notable political liberal authors, who opposed monarchies and absolutism, were Voltaire, Jean-Jacques Rousseau, Montesquieu, Denis Diderot and Jean Le Rond d'Alembert, while the most notorious economic liberal was Adam Smith. Liberal ideas also reached the church, and the concept of the divine right of kings started to be questioned. Francisco Suárez claimed that political power did not pass directly from God to the governor, but to the population and through it to the governor. According to Suarez, such power belongs to the people and is delegated to the governor, but if such governors did not serve the public good as they should, they would become tyrants and the people would have the right to fight them and choose new governors. The falling consensus about the divine right being legitimate gave room to monarchies being replaced by republics in France and the United States, but also to constitutional monarchies, such as in Great Britain.
