The Mughan Soviet Republic was a short-lived pro-Bolshevik state that existed in present-day southeastern Azerbaijan from March to June 1919. It was founded in opposition to the Azerbaijan Democratic Republic in Baku. It was proclaimed mostly by the ethnic Russian part of the population of the region,[1] and ceased to exist when the army of the Azerbaijan Democratic Republic took control over the region.[2]
