The 1811 Independence Movement known in El Salvador as the Primer grito de independencia (First Shout of Independence) was the first of a series of revolts in Central America in El Salvador against Spanish colonialism and dependency on the Captaincy General of Guatemala.
At the beginning of the 19th century, agitation grew in the American territories dominated by the Spanish crown. The previous century was dominated by the growing support of ideas of individual freedom, which characterized the Enlightenment that took place in Europe and the Americas. Most influential was the American Revolution, with the resulting liberation of the British North American colonies, and the French Revolution, which seeded the restlessness and search for freedom in the Spanish American territories under dominion of the Spaniards.
In the Intendancy of San Salvador (covering roughly the same territory as today's El Salvador), many Creoles and other settlers wanted to separate control of the colony from the Guatemalan Captaincy General. This was largely due to economic and political reasons. Greater administrative autonomy or outright independence for San Salvador would reduce the high level of taxes paid to Spain and Guatemala and would raise finances for the colony. Napoleón Bonaparte's invasion of Spain in 1808 and the removal of Ferdinand VII from the Spanish throne created an atmosphere of unrest in San Salvador.
The insurrectionists organized themselves along with prominent middle-class supporters of the cause of independence such as doctors and priests who took part in the event. These included doctors such as Santiago José Celis, the brothers (Nicholas, Vicente and Manuel Aguilar) and the priest José Matías Delgado. Others included Manuel José Arce, Juan Manuel Rodríguez and Pedro Pablo Castillo.
