At the time of Greece's liberation in October 1944, EAM-ELAS dominated the country except for the major cities, especially Athens, where British forces supported the returned Greek government in exile. As from the return of the exiled government, a new headed by Georgios Papandreou was established in Greece, with the participation of EAM and KKE, according to the Caserta Agreement. The internal disagreements of the government, resulted in the withdrawal of the EAM ministers. The dormant rivalry between the Papandreou's government, backed by the British, and EAM-ELAS, resulted in the "Dekemvriana" clashes in Athens (December 1944 – January 1945), where EAM-ELAS was defeated, and the disarmament of the organization in the Treaty of Varkiza (February 1945).
