Arauco War: The first Parliament of Quillín is celebrated, putting a temporary hold on hostilities between Mapuches and Spanish in Chile.

The Arauco War was a long-running conflict between colonial Spaniards and the Mapuche people, mostly fought in the Araucanía region of Chile. The conflict began at first as a reaction by the Mapuche to the Spanish conquerors attempting to establish cities and force the natives into servitude. It subsequently evolved over time into phases comprising drawn-out sieges, slave-hunting expeditions, pillaging raids, punitive expeditions, and renewed Spanish attempts to secure lost territories. Abduction of women and war rape was common on both sides.
