The Armenian National Council declared the independence of Armenia on 28 May 1918 . From the very onset , Armenia was plagued with a variety of domestic and foreign problems . A humanitarian crisis emerged from the aftermath of the Armenian Genocide as tens of thousands of Armenian refugees from the Ottoman Empire settled there . The republic lasted for over two years , during which time it was involved in several armed conflicts caused by territorial disputes . By late 1920 , the nation was conquered by the Soviet Red Army . The First Republic , along with the Republic of Mountainous Armenia which repelled the Soviet invasion until July 1921 , ceased to exist as an independent state , superseded by the Armenian Soviet Socialist Republic that became part of the Soviet Union in 1922 . After the fall of the Soviet Union , the republic regained its independence as the current Republic of Armenia in 1991
