What role over the Hellenic Army did the person who had a dispute with Eleftherios Venizelos have?
Constantine I of Greece Constantine I (Greek: Κωνσταντῖνος Α΄ , "Konstantínos I"; 2 August [O.S. 21 July] 1868 – 11 January 1923) was King of Greece from 1913 to 1917 and from 1920 to 1922. He was commander-in-chief of the Hellenic Army during the unsuccessful Greco-Turkish War of 1897 and led the Greek forces during the successful Balkan Wars of 1912–1913, in which Greece expanded to include Thessaloniki, doubling in area and population. He succeeded to the throne of Greece on 18 March 1913, following his father's assassination.
French military mission to Greece (1911–14) The 1911–1914 French military mission to Greece was called to Greece by the government of Eleftherios Venizelos to reorganize the Hellenic Army, parallel to a British naval mission for the Royal Hellenic Navy. The French mission arrived in January 1911, under the command of General Joseph-Paul Eydoux, replaced in April 1914 by General Étienne de Villaret (who had also served in a mission to Japan earlier in his career). It remained in the country until the outbreak of World War I in August 1914, when it was repatriated.
