However, over the course of the war, effective power changed to the hands of Josip Broz Tito's Communist Partisans. In 1943, Tito proclaimed the creation of the Democratic Federative Yugoslavia ("Demokratska federativna Jugoslavija"). The Allies gradually recognized Tito's forces as the stronger opposition forces to the German occupation. They began to send most of their aid to Tito's Partisans, rather than to the Royalist Četniks. On 16 June 1944, the Tito–Šubašić agreement was signed which merged the "de facto" and the "de jure" government of Yugoslavia.
