Mapuches in Chile launch a series of surprise attacks against the Spanish starting the Mapuche uprising of 1766.

The Mapuche, also known as Araucanians, are a group of Indigenous inhabitants of south-central Chile and southwestern Argentina, including parts of Patagonia. The collective term refers to a wide-ranging ethnicity composed of various groups who share a common social, religious, and economic structure, as well as a common linguistic heritage as Mapudungun speakers. Their homelands once extended from Choapa Valley to the Chiloé Archipelago and later spread eastward to Puelmapu, a land comprising part of the Argentine pampa and Patagonia. Today the collective group makes up over 80% of the Indigenous peoples in Chile and about 9% of the total Chilean population .The Mapuche are concentrated in the Araucanía region. Many have migrated from rural areas to the cities of Santiago and Buenos Aires for economic opportunities, more than 92% of the Mapuches are from Chile.

In Chilean historiography, Colonial Chile is the period from 1600 to 1810, beginning with the Destruction of the Seven Cities and ending with the onset of the Chilean War of Independence. During this time, the Chilean heartland was ruled by Captaincy General of Chile. The period was characterized by a lengthy conflict between Spaniards and native Mapuches known as the Arauco War. Colonial society was divided in distinct groups including Peninsulars, Criollos, Mestizos, Indians and Black people.
