The Dagestan Autonomous Soviet Socialist Republic (1921–1991), abbreviated as Dagestan ASSR or DASSR and also unofficially known as Soviet Dagestan or just simply Dagestan, was an autonomous republic of the Russian SFSR within the Soviet Union. This "Land of Mountains" was known also for having a "mountain of peoples," with more than thirty ethnic groups indigenous to the territory. This region was absorbed in to the Russian Empire in 1813 after the signing of the Treaty of Gulistan, and subsequently became a breeding ground for early revolutionary fervor in the Russian Revolution due its people's discontent with being part of the empire.
