Assembly of Captive European Nations or ACEN was an organization founded on September 20, 1954, as a coalition of representatives from nine nations in Central and Eastern Europe under Soviet domination after World War II. Former political and cultural leaders from Albania, Bulgaria, Czechoslovakia, Estonia, Hungary, Latvia, Lithuania, Poland and Romania were members of the organization. Its main office was in New York, with branch offices in Bonn, London and Paris. Representatives from post-1948 SFR Yugoslavia were not allowed to join the organization as the country was an important western partner in the Balkans region.[1]
