The Tawantinsuyu (Quechua: "land of the four quarters") or Inca Empire was a centralized bureaucracy. It drew upon the administrative forms and practices of previous Andean civilizations such as the Wari Empire and Tiwanaku, and had in common certain practices with its contemporary rivals, notably the Chimor. These institutions and practices were understood, articulated, and elaborated through Andean cosmology and thought. Following the Spanish conquest of the Inca Empire, certain aspects of these institutions and practices were continued.
