The Communist Party of Croatia (CPC), i.e., the League of Communists of Croatia (LCC), as part of the League of Communists of Yugoslavia (LCY), was the sole governing political party in Yugoslavia and Croatia during the socialist era (1945-1990). Its members assumed the leading positions in all fields of state and social life. Party organizations in Yugoslavia, as well as Party organizations in its federal units, were managed by their central committees as the highest organs of the Party between the two congresses. To accomplish defined program objectives, LC CC elected the constituent, executive political body (Political Bureau or Politburo, 1937-1952, Executive Council, 1952-1974, Presidium, 1974-1989). To carry out specific tasks, the Executive Council established working bodies - permanent or interim commissions to deal with specific issues.
