Autonomous oblast
An autonomous oblast (Russian: Автономная область (АО)) is an autonomous form of an oblast (administrative-territorial structure) in the USSR. Of the post-Soviet states, autonomous oblasts currently exist only in Russia (the Jewish Autonomous Oblast) and Tajikistan (the Gorno-Badakhshan). There were autonomous oblasts of the Soviet Union and later some federal subjects of Russia were autonomous oblasts: the one remaining is the Jewish Autonomous Oblast.
