The Colla, Qolla or Qulla Kingdom was established in the northwestern basin of the Titicaca, one of the Aymara kingdoms that occupied part of the Collao plateau after the fall of Tiwanaku. In the mid-15th century the Collas possessed a vast territory, one of the largest of the Aymara kingdoms, which at the time the 9th Sapa Inca Pachacuti Yupanqui Capac Intichuri conquered along with other political entities in the region.
The Inca empire named the Qullasuyo or Colla Region towards a larger region than the original Colla Kingdom, as the Aymara kingdoms with strong cultural ties between them were called by the Incas with the collective term of "Colla" as it was for them the most significant of them all.
The Qulla were organized into two regions (Quechua and Aymara: Suyu): Urcosuyu (Urco: male, fire) and Umasuyu (Uma: female, water).
Their capital was Hatunqulla, ie "Colla, the Great" located 34 km north of Puno in the Urcusuyu and was ruled by the dynasty of the Zapanas. The capital of the Umasuyu was Azangaro, which depended on Hatunqulla. This form of government based on duality was characteristic of the central Andean societies, in which both parts were complementary but one still ruled over the other, the Inca for example divided their empire and society in Hanan (Quechua: Upper) and Hurin (Quechua: Lower).
The Urcosuyu had the towns of Hatuncolla, Caracoto, Juliaca, Nicasio, Lampa, Cabana, Cabanilla, Mañazo, Ullagachi, Paucarcolla, Capachica and Coata.
