Prior to 1992, the Chuvash Republic existed as the Chuvash Autonomous Soviet Socialist Republic. Prior to 1937, Chuvash ASSR used a flag with traditional motifs of Chuvashia and the name of the ASSR. The motifs was deleted later in 1931 due to the traditional motifs being associated with chauvinism and bourgeois nationalism. After 1937, the flag of the Chuvash ASSR was identical to the flag of the Russian SFSR.
