Colocolo was a Mapuche leader in the early period of the Arauco War. He was a major figure in Alonso de Ercilla y Zúñiga's epic poem La Araucana, about the early Arauco War. In the poem he was the one that proposed the contest between the rival candidates for Toqui that resulted in the choice of Caupolicán. As a historical figure there are some few contemporary details about him. Stories of his life were written long after his lifetime and display many points of dubious historical accuracy.
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 to the Spanish conquerors attempting to establish cities and force Mapuches 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.
Toqui is a title conferred by the Mapuche on those chosen as leaders during times of war. The toqui is chosen in an assembly or parliament (coyag) of the chieftains (loncos) of various clans (Rehues) or confederation of clans (Aillarehues), allied during the war at hand. The toqui commanded strict obedience of all the warriors and their loncos during the war, would organize them into units and appoint leaders over them. This command would continue until the toqui was killed, abdicated (Cayancaru), was deposed in another parliament, or upon completion of the war for which he was chosen.
The Battle of Tucapel is the name given to a battle fought between Spanish conquistador forces led by Pedro de Valdivia and Mapuche (Araucanian) Indians under Lautaro that took place at Tucapel, Chile on December 25, 1553.

The battle is notable for ending Mapuche designs on Santiago, while also avenging the death of former governor Pedro de Valdivia, who had been killed by Lautaro's warriors four years earlier.
The Battle of Millarapue that occurred November 30, 1557 was intended by the Toqui Caupolicán as a Mapuche ambush of the Spanish army of García Hurtado de Mendoza that resulted in a Spanish victory when the ambush failed.

Alonso Diaz was a mestizo Spanish soldier offended because the Governor of Chile did not promote him to the officer rank of alféres, who subsequently went over to the Mapuche in 1572. He took the Mapuche name of Paineñamcu and because of his military skills was elected toqui in 1574 following the death of Paillataru.

Pedro de Avendaño a Spanish soldier that had arrived in Chile with the army of García Hurtado de Mendoza in 1557. He distinguished himself in the Battle of Millarapue. He later served in the garrison of Cañete under captain Alonso de Reinoso. Reinoso eventually found an Indian who betrayed the location of the fugitive Mapuche toqui Caupolicán. Avendaño, with 50 men and the traitorous Indian as a guide, marched in stormy weather into the mountains to Pilmaiquén and captured Caupolicán as he was planning a new counter-offensive against the Spanish, near the modern Antihuala, on February 5, 1558. He brought the toqui back to Cañete where he was eventually executed by impalement at the order of corregidor Reinoso.
Llanganabal was a Moluche toqui who led the Mapuche army that defeated the Spanish led by Martín Ruiz de Gamboa in the Battle of Catirai in 1569. In 1560 Llanganabal is listed as one of the caciques heading an encomienda along the Bio Bio River. Shortly after began the outbreak of the 1561 Mapuche revolt. By 1569 Llanganabal had risen to command the Araucan army with Millalelmo and other captains as his subordinates. To resist the Spanish who had been burning the fields and houses on the south bank of the Bio Bio, Millalelmo had built a strong fortress on a hill in Catirai in a difficult position on steep wooded slopes. Despite the warnings of Lorenzo Bernal del Mercado who had reconnoitered the position, Spaniards new to Chile and the Arauco War prevailed on Governor Melchor Bravo de Saravia to order Martín Ruiz de Gamboa to take his command and attack the place. Meanwhile, Llanganabal had gathered all his army there to resist the attack. Gamboa's force was badly defeated while attempting to attack up the steep thickly wooded hill into Llanganabal's fortified position.
The Battle of Catirai took place on January 7, 1569, near Catirai, Chile between the Mapuche army of Toqui Llanganabal and the Spanish army led by Martín Ruiz de Gamboa that resulted in a Mapuche victory.
