Azerbaijan Democratic Republic

The Azerbaijan Democratic Republic (Azerbaijani: Azərbaycan Demokratik Cümhuriyyəti), also known as the Azerbaijan People's Republic (Azerbaijani: Azərbaycan Xalq Cümhuriyyəti; آذربایجان خلق جمهوریتی‎), was the first secular democratic republic in the Turkic and Muslim worlds. The ADR was founded by the Azerbaijani National Council in Tiflis on 28 May 1918 after the collapse of the Transcaucasian Democratic Federative Republic, and ceased to exist on 28 April 1920.
