Government of the Inca Empire
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.
