Killaka

The Killaka or Quillacas were one of the Aymara-speaking lordships of the southern Bolivian altiplano, holding the country around present Uyuni and the Aullagas basin south of Lake Poopó, in what is now the department of Oruro. With the Aullagas, Chichas and neighboring groups they belonged to the Charca federation, whose highland ayllus traded with the valleys and stood together against Guaraní raids from the Chaco.

After the Inca conquest their land became the huamani of Quillaca, counted among the twenty-eight provinces of Collasuyo. Under Spanish rule the old chiefdom survived as Hatun Quillacas: the noble José Fernández Collque Inca Guarachi held its caciqueship from 1681 to 1734, and the town of Santuario de Quillacas preserves the people's name.
