The Azerbaijan Soviet Socialist Republic^[d], also referred to as the Azerbaijani Soviet Socialist Republic, Azerbaijan SSR, Azerbaijani SSR, AzSSR, Soviet Azerbaijan or simply Azerbaijan, was one of the constituent republics of the Soviet Union between 1922 and 1991. Created on 28 April 1920 when the Russian Soviet Federative Socialist Republic brought pro-Soviet figures to power in the region, the first two years of the Azerbaijani SSR were as an independent country until incorporation into the Transcaucasian SFSR, along with the Armenian SSR and the Georgian SSR.

In December 1922, the Transcaucasian SFSR became part of the newly established Soviet Union. The Constitution of Azerbaijan SSR was approved by the 9th Extraordinary All-Azerbaijani Congress of Soviets on 14 March 1937. On 5 February 1991, Azerbaijan SSR was renamed the Republic of Azerbaijan according to the Decision No.16-XII of Supreme Soviet of Azerbaijan approving the Decree of the President of Azerbaijan SSR dated 29 November 1990,^[3] remained in the USSR for the period before the declaration of independence in October 1991. The Constitution of the Azerbaijan SSR ceased to exist in 1995, upon the adoption of the new Constitution of Azerbaijan.
