An autonomous administrative division is an administrative division of a country that has a degree of autonomy, or freedom from an external authority. Typically it is either geographically distinct from the rest of the country or populated by a national minority. Decentralization of self-governing powers and functions to such divisions is a way for a national government to try to increase democratic participation or administrative efficiency and/or to defuse internal conflicts. Countries that include autonomous areas may be federacies, federations, or confederations. Autonomous areas can be divided into territorial autonomies, subregional territorial autonomies, and local autonomies.
