George I of Greece [SEP] Introduction
George I (Greek: Γεώργιος Α΄, "Geórgios I"; 24 December 1845 – 18 March 1913) was King of Greece from 30 March 1863 until his assassination in 1913. Originally a Danish prince, he was born in Copenhagen, and seemed destined for a career in the Royal Danish Navy. He was only 17 years old when he was elected king by the Greek National Assembly, which had deposed the unpopular Otto. His nomination was both suggested and supported by the Great Powers: the United Kingdom of Great Britain and Ireland, the Second French Empire and the Russian Empire. He married Grand Duchess Olga Constantinovna of Russia in 1867, and became the first monarch of a new Greek dynasty.
