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 Industrial Revolution started in Britain, with manual labour and horse-drawn vehicles being replaced by machine-based manufacturing and transportation aided by railways and steam power. This led to dramatic increases in the productive capabilities of Britain, and the need of new markets to sell the surplus of coal, steel and clothes. The Napoleonic Wars, where Britain was at war with France, made this a difficult task, after Napoleon countered the British naval blockade with the Continental System, not allowing Britain to trade with any other European country. Thus, England needed to be able to trade with the Spanish colonies, but could not do so because they were restricted to trade only with their own metropoli. For this end they tried to conquer key cities during the British invasions, and after it to promote their emancipation. The Industrial Revolution also gave room to authors who proposed a liberal economy, like Adam Smith. François Quesnay compared the worldwide economy with a living organism, stating that economics worked beyond political power and should not be affected by it.
