      Constantine I (Greek: Κωνσταντίνος Αʹ, Konstantínos I; 2 August [O.S . 2 1 July] 1868 – 11 January 1923) was King of Greece from 1913 to 191 7 an d from 1920 to 1922. He was commander-in-chief of the Hellenic Arm y durin g the unsuccessful Greco-Turkish War of 1897 and led the Greek fo rces dur ing the successful Balkan Wars of 1912–1913, in which Greece exp anded t o include Thessaloniki, doubling in area and population. He succe eded t o the throne of Greece on 18 March 1913, following his father's as sassina tion.

      His disagreement with Eleftherios Venizelos over whether Greece should e n ter World War I led to the National Schism. Constantine forced Venizel o s to resign twice, but in 1917 he left Greece, after threats by the Ent en te forces to bombard Athens; his second son, Alexander, became king. A fte r Alexander's death, Venizelos' defeat in the 1920 legislative electi ons , and a plebiscite in favor of his return, Constantine was reinstated . H e abdicated the throne for the second and last time in 1922, when Gre ec e lost the Greco-Turkish War of 1919–1922, and was succeeded by his el des t son, George II. Constantine died in exile four months later, in Sic ily.
