Arauco War: Spanish and Mapuche authorities meet in the Parliament of Boroa renewing the fragile peace established at the parliaments of Quillín in 1641 and 1647.

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.
