The People's Republic of Bulgaria (PRB) was the official name of the Bulgarian state from 1946 to 1990, when it was under the rule of the Bulgarian Communist Party (BCP). Bulgaria was an Eastern Bloc country and a Soviet ally during the Cold War, a member of the Warsaw Pact and the Comecon. After the fall of Communism in Eastern Europe, BCP transformed itself in 1990, changing its name to Bulgarian Socialist Party.
