Constantine I of Greece

Constantine I was King of Greece from 1913 to 1917 and from 1920 to 1922. He was commanderinchief of the Hellenic Army during the unsuccessful GrecoTurkish War of 1897 and led the Greek forces during the successful Balkan Wars of 19121913, in which Greece expanded to include Thessaloniki, doubling in area and population. He succeeded to the throne of Greece onMarch 1913, following his fathers assassination.

Constantines military judgement was born out by the outcome of the Allies disastrous landing on Gallipoli. Despite the popularity of Venizelos and his clear majority in Parliament, Constantine opposed Venizeloss increasing support for the Allies. When Bulgaria attacked Serbia, with whom Greece had a treaty of alliance, Venizelos again urged the King to allow Greeces entry into the war, and permitted Entente forces to disembark in Thessaloniki in preparation for a common campaign over the Kings objections. After Constantine refused again to support Greeces entry on the side of the Allies, however, Venizelos resigned, and Constantine appointed Alexandros Zaimis in his place, at the head of a shortlived coalition government.
