 In 1946 the People's Republic of Macedonia was recognized by the new communist constitution as a federal component of the newly proclaimed Federal People's Republic of Yugoslavia under the leadership of Josip Broz Tito.The issue of the republic's name immediately sparked controversy with Greece over Greek concerns that it presaged a territorial claim on the Greek coastal region of Macedonia (see Territorial concerns below).The U.S. Roosevelt administration expressed the same concern through Edward Stettinius in 1944.
