Supported by Moscow, he was appointed leader of the Communist Party of Slovakia in as early as August 1968, and he succeeded Dubček as first secretary (title changed to general secretary in 1971) of the Communist Party of Czechoslovakia in April 1969. He reversed Dubček's reforms and purged the party of its liberal members in 1969–1971. In 1975, Husák was elected President of Czechoslovakia.
