Red Army invasion of Azerbaijan
The Red Army invasion of Azerbaijan, also known as the Sovietization or Soviet invasion of Azerbaijan, was a military campaign carried out by the 11th Army of Soviet Russia in April 1920 to install a new Soviet government in the Azerbaijan Democratic Republic. The invasion coincided with the anti-government insurrection staged by the local Azerbaijani Bolsheviks in the capital, Baku. The invasion led to the dissolution of the Azerbaijan Democratic Republic and the establishment of the Azerbaijan Soviet Socialist Republic.
