The Estonian Soviet Socialist Republic (Estonian: Eesti Nõukogude Sotsialistlik Vabariik; Russian: Эстонская Советская Социалистическая Республика, Estonskaya Sovetskaya Sotsalisticheskaya Respublika), often abbreviated as Estonian SSR or ESSR, was a republic of the Soviet Union, administered by and subordinated to the Government of the Soviet Union. The ESSR was initially established on the territory of the Republic of Estonia on July 21, 1940, following the invasion of Soviet troops on June 17, 1940 and the installation of a puppet government backed by the Soviet Union, which declared Estonia a Soviet state. The Estonian SSR was subsequently incorporated into the USSR on August 9, 1940.
