Georges I Roi des Hellines 1845 - George I, King of the Hellenes (24th December 1845 - 18th March 1913) was King from 1863 to 1913. Originally a Danish prince, when only 17-years old he was elected as King by the Greek National Assembly, which had deposed the former King Otto. His nomination was both suggested and supported by the Great Powers (United Kingdom of Great Britain and Ireland, Second French Empire and the Russian Empire). As the first monarch of the new Greek dynasty, his 50-year reign (the longest in modern Greek history) was characterized by territorial gains as Greece established its place in pre-World War I Europe. Two weeks short of the fiftieth anniversary of his accession, and during the First Balkan War, he was assassinated. 1845-1852: His Highness Prince Vilhelm of Schleswig-Holstein-Sonderburg-Glksburg 1852-1858: His Highness Prince Vilhelm of Denmark 1858-1863: His Royal Highness Prince Vilhelm of Denmark 1863-1913: His Majesty King George I of the Hellenes, Prince of Denmark ?007 TopFoto
