Alexander Dubček

Alexander Dubček was a Slovak statesman who served as the First Secretary of the Presidium of the Central Committee of the Communist Party of Czechoslovakia (KSČ) from January 1968 to April 1969 and as Chairman of the Federal Assembly from 1989 to 1992 following the Velvet Revolution. He oversaw significant reforms to the communist system during a period that became known as the Prague Spring, but his reforms were reversed and he was eventually sidelined following the Warsaw Pact invasion in August 1968.
