The beginning of the Peninsular War in Spain and the capture of the Spanish king Ferdinand VII created great concern all around the viceroyalty. It was thought that, without a King, people in America should rule themselves. This idea led to multiple attempts to remove the local authorities at Chuquisaca, La Paz, Montevideo and Buenos Aires, all of which were short-lived. A new successful attempt, the May Revolution of 1810, took place when it was reported that all of Spain, with the exception of Cádiz and León, had been conquered.
