Cangapol was a Tehuelche cacique born in the area of Huilin, on the Negro River in today's Argentina from 1735 to 1752. He was the chieftain of the nomadic Leuvuche people, who moved through a huge area from the Negro River to the Vulcan hills, today known as Tandilia hills, between the modern cities of Tandil and Mar del Plata. The Leuvuches were in fact called Serranos (people from the hills) by the Spaniards. In 1751, Cangapol and his warriors expelled the Jesuits from Laguna de los Padres and destroyed the settlement built by them five years before. In 1753, he became an allied of the Spaniards against the Mapuches, who used to take profit of the Leuvuches' plunder raids north of the Salado river and then sought safe haven in Chile, leaving the Leuvuches to face the Spanish retaliation alone. He died the same year and was succeeded by his son Nicolás.
