After Liberation in October 1944, the tensions between ΕΑΜ and anticommunist forces, which were supported by Britain, escalated.
Originally, as agreed at the Lebanon conference, ΕΑΜ participated in the government of national unity under George Papandreou with 6 ministers.
Disagreements regarding the disarmament of ELAS and the formation of a national army made their ministers, on 1 December, resign.
ΕΑΜ organized a demonstration in Athens on 3 December 1944 against British interference.
The exact details of what happened have been debated ever since, but gendarmes opened fire on the crowd, resulting in 25 dead protesters (including a six-year-old boy) and 148 wounded.
The clash escalated into a month-long conflict between ELAS and the British and Greek governmental forces, known as the "December events" (Dekemvrianá), which resulted in a government victory.

In February, the Varkiza agreement was signed, leading to the disbandment of ELAS.
In April, the SKE and ELD parties left ΕΑΜ.
ΕΑΜ was not dissolved but was now for all intents and purposes merely an expression of the ΚΚΕ.
During the 1945-1946 period, a conservative terror campaign (the "White Terror") was launched against ΕΑΜ-ΚΚΕ supporters.
The country became polarized, eventually leading to the outbreak of the Greek Civil War in March 1946, which lasted until 1949.
