Upon the establishment of the Azerbaijan Democratic Republic, the Baku Governorate was incorporated into the fledgling state and subsequently separated into a smaller Baku General-Governorate and a Lenkoran General-Governorate, the latter being the location of the Provisional Military Dictatorship of Mughan which was suppressed in spring 1919.
When Azerbaijan gained independence, the Baku Governorate became part of it and subsequently split into two smaller administrative regions: a Baku General-Governorate and a Lenkoran General-Governorate. The Provisional Military Dictatorship of Mughan in Lenkoran was eventually dismantled in spring 1919.
