Page "History of Chile" Paragraph 24

The beginning of the Independence movement is traditionally dated as September 18, 1810 when a national junta was established to govern Chile in the name of the deposed king Ferdinand VII.

Depending on what terms one uses to define the end, the movement extended until 1821 ( when the Spanish were expelled from mainland Chile ) or 1826 ( when the last Spanish troops surrendered and Chiloé was incorporated to the Chilean republic ).

The independence process is normally divided into three stages: Patria Vieja, Reconquista, and Patria Nueva.
