The Chuvash Autonomous Soviet Socialist Republic (Chuvash: Чӑваш Автономлӑ Совет Социаллӑ Республики|Chăwash Avtonomlă Sovet Sociallă Respubliki; Russian: link=no|Чувашская Автономная Советская Социалистическая Республика|Chuvashskaya Avtonomnaya Sovetskaya Sotsialisticheskaya Respublika) was an autonomous republic of the Russian SFSR within the Soviet Union.
It occupied about 18000km2 along the east bank of the Volga River, about 60km (40miles) west of the river's confluence with the Kama River and some 700km (400miles) east of Moscow.
The successor of the Chuvash Autonomous Oblast, the Chuvash ASSR was formed in 1925.[1] It declared its sovereignty within the Soviet Union in 1990 as the Chuvash Republic (still within Russia).
Its primary economic activities were agricultural.[1] Grain and fruit production and logging are emphasized. The capital city was Cheboksary.[1]
