 Greece and Serbia found themselves being the winner parties by having successfully fought the war side by side.Despite its defensive alliance with Serbia, Greece remained neutral in the early part of the First World War, due to the dissension between Prime Minister Eleftherios Venizelos, who was pro-Entente and favoured entering the war, and King Constantine I of Greece, who was pro-German and favoured neutrality.The resulting National Schism was resolved only in 1917, when Constantine was forcibly deposed by the Entente Powers and Greece entered the war under Venizelos.
