Lautaro was a young Mapuche toqui known for leading the indigenous resistance against Spanish conquest in Chile and developing the tactics that would continue to be employed by the Mapuche during the long-running Arauco War. Levtaru was captured by Spanish forces in his early youth, and he spent his teenage years as a personal servant of chief conquistador Pedro de Valdivia, but escaped in 1551. Back among his people he was declared toqui and led Mapuche warriors into a series of victories against the Spanish, culminating in the Battle of Tucapel in December 1553, where Pedro of Valdivia was killed. The outbreak of a typhus plague, a drought and a famine prevented the Mapuche from taking further actions to expel the Spanish in 1554 and 1555. Between 1556 and 1557, a small group of Mapuche commanded by Levtaru attempted to reach Santiago to liberate the whole of Central Chile from Spanish rule. Levtaru's attempts ended in 1557 when he was killed in an ambush by the Spanish.

The Mapuche 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.
