Tajiks began to be conscripted into the Soviet Army in 1939 and during World War II around 260,000 Tajik citizens fought against Germany, Finland and Japan. Between 60,000(4%) and 120,000(8%) of Tajikistan's 1,530,000 citizens were killed during World War II. Following the war and Stalin's reign attempts were made to further expand the agriculture and industry of Tajikistan. During 1957–58 Nikita Khrushchev's Virgin Lands Campaign focused attention on Tajikistan, where living conditions, education and industry lagged behind the other Soviet Republics. In the 1980s, Tajikistan had the lowest household saving rate in the USSR, the lowest percentage of households in the two top per capita income groups, and the lowest rate of university graduates per 1000 people. By the late 1980s Tajik nationalists were calling for increased rights. Real disturbances did not occur within the republic until 1990. The following year, the Soviet Union collapsed, and Tajikistan declared its independence.
