The Chilean War of Independence (Spanish: Guerra de la Independencia de Chile, 'War of Independence of Chile') was a military and political event that allowed the emancipation of Chile from the Spanish Monarchy, ending the colonial period and initiating the formation of an independent republic.
It developed in the context of the Spanish American Wars of independence, a military and political process that began after the formation of self-government juntas in the Spanish-American colonies, in response to the capture of King Ferdinand VII of Spain by Napoleonic forces in 1808. The First Government Junta of Chile was formed for that purpose. But then, it began to gradually radicalize, which caused a military struggle between Patriots, who were looking for a definitive separation from the Spanish Crown; and Royalists, who sought to maintain unity with her.
