Constantine II of Greece (Crown of the Emperor)

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. He was commander-in-chief of the Hellenic Army during the Russo-Turkish War of 1897. He succeeded to the throne of Greece on 18 March 1913, following his father's assassination. Following a series of disagreements with Prime Minister Eleftherios Venizelos over the conflict between France and Prussia, Venizelos was pro-French while Constantine was pro-Prussian. Constantine abdicated in 1917 in favour of his second eldest son, Alexander and he died in exile in France at the age of 54.
