Russians who moved to Uzbekistan, other nationalities such as Crimean Tatars, Chechens, and Koreans were exiled to the republic because Moscow saw them as subversive elements in European Russia. Khrushchev and Brezhnev rule Following the death of Joseph Stalin in 1953, the relative relaxation of totalitarian control initiated by First Secretary Nikita Khrushchev (in office 1953–64) brought the rehabilitation of some of the Uzbek nationalists who had been purged. More Uzbeks began to join the Communist Party of Uzbekistan and to assume positions in the government. However, those Uzbeks who participated in the regime did so on Russian terms. Russian was the language of state, and Russification was the prerequisite for obtaining a position in the government or the party. Those who did not or could not abandon their Uzbek lifestyles and identities were excluded from leading roles in official Uzbek society. Because of these conditions, Uzbekistan gained a reputation as one of the most politically conservative republics in the Soviet Union. As Uzbeks were beginning to gain leading positions in society, they also were establishing or reviving unofficial networks based on regional and clan loyalties. These networks provided their members support and often profitable connections between them and the state and the party. An extreme example of this phenomenon occurred under the leadership of Sharaf Rashidov, who was first secretary of the Communist Party of Uzbekistan from 1959 to 1982. During his tenure, Rashidov brought numerous relatives and associates from his native region into government and party leadership positions. The individuals who thus became "connected" treated their positions as personal fiefdoms to enrich themselves. In this way, Rashidov was able to initiate efforts to make Uzbekistan less subservient to Moscow. As became apparent after his death, Rashidov's strategy had been to remain a loyal ally of Leonid Brezhnev, leader of the Soviet Union from 1964 to 1982, by bribing high officials of the central government. With this advantage, the Uzbek government was allowed to merely feign compliance with Moscow's demands for increasingly higher cotton quotas. The 1980s Moscow's control over Uzbekistan weakened in the 1970s as Uzbek party leader Sharaf Rashidov brought many cronies and relatives into positions of power. In the mid-1980s, Moscow attempted to regain control by again purging the entire Uzbek party leadership. However, this move increased Uzbek nationalism, which had long resented Soviet policies such as the imposition of cotton monoculture and the suppression of
