The State of Buryat-Mongolia was a buffer Buryat-Mongolian state,[1] during the Russian Civil War. The main government body was Burnatskom, the Buryat National Committee.[1]
The state de facto ceased to exist after the formation of the Far Eastern Republic, which divided Buryat-Mongolia in two: 4 aimags became part of the Far Eastern Republic, while the other 4 formed Buryat-Mongol autonomies of RSFSR.
