Qulla

Qullasuyu (Quechua and Aymara spelling, ; Collasuyu, Kholla Suyu; ) was the southeastern provincial region of the Inca Empire. Qullasuyu is the region of the Qulla and related specifically to the native Qulla Quechuas who primarily resided in areas such as Cochabamba and Potosí. Most Aymara territories which are now largely incorporated into the modern South American states of northern Chile, Peru, Bolivia and the Argentine Northwest were conquered during the reign of Sapa Inca Huayna Cápac in the sixteenth century.

The Qulla (Quechuan for south, Hispanicized and mixed spellings: Colla, Kolla) are an Indigenous people of western Bolivia, northern Chile, and the western portions of Jujuy and Salta provinces in Argentina. The 2004 Complementary Indigenous Survey reported 53,019 Qulla households living in Argentina. They moved freely between the borders of Argentina and Bolivia. While mostly living in arid highlands, their easternmost lands are part of the yungas, an altitude forests at the edge of the Amazon rainforest.
