Prior to the fall of the USSR and the archival revelations, some historians estimated that the numbers killed by Stalin's regime were 20 million or higher.[4][5][6] After the USSR fell, evidence from the Soviet archives also became available, containing official records of 799,455 executions (1921–1953),[7] around 1.7 million deaths in the Gulag[8][9] some 390,000[10] deaths during kulak forced resettlement and up to 400,000 deaths of persons deported to Forced settlements in the Soviet Union during the 1940s[11] – with a total of about 3.3 million officially recorded victims in these categories.[12] The deaths of at least 5.5 to 6.5 million[13] persons in the famine of 1932–33 are sometimes, but not always,[11][12] included with the victims of the Stalin era.
