This article examines the liquidation of the Greek Catholic Church in Czechoslovakia following the Communist takeover in February 1948. The Greek Catholic Church was to be separated from the mother Catholic Church and incorporated into the Orthodox Church. The process culminated at the irregular Sobor (synod) of Prešov held on 28 April 1950. The synod was orchestrated and headed by the ruling Communist party, which enforced its conclusions. Greek Catholics were either outlawed or compelled to become Orthodox, although their situation slightly brightened during the Prague Spring of 1968 when their Church became legal again.
