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 Sapan Inka Pachakutiq Yupanqui Qhapaq the Intipchurin ("son of the sun"), conquered along with other political entities in the region.
