After the collapse of the Russian Empire during World War I, the short-lived Transcaucasian Democratic Federative Republic was declared, constituting what are the present-day republics of Azerbaijan, Georgia, and Armenia. This was followed by March Days massacres that took place between 30 March and 2 April 1918 in the city of Baku and adjacent areas of the Baku Governorate of the Russian Empire. When the republic dissolved in May 1918, the leading Musavat party adopted the name "Azerbaijan" for the newly established Azerbaijan Democratic Republic, which was proclaimed on 27 May 1918, for political reasons, even though the name of "Azerbaijan" had always been used to refer to the adjacent region of contemporary northwestern Iran. The ADR was the first modern parliamentary republic in the Turkic world and Muslim world. Among the important accomplishments of the Parliament was the extension of suffrage to women, making Azerbaijan the first Muslim nation to grant women equal political rights with men. Another important accomplishment of ADR was the establishment of Baku State University, which was the first modern-type university founded in Muslim East.
