George I (of Greece) (1845-1913), king of Greece (1863-1913), the first Greek
monarch of the house of Glücksburg. The second son of King Christian IX of
Denmark, he was known as Prince William and was nominated for the Greek throne
by the British government after the revolution that deposed his predecessor,
King Otto, in 1862. The Danish prince was elected to the throne by the Greek
National Assembly and was crowned as George I, king of the Hellenes, after
being approved by the Great Powers. In 1867 he married Olga, niece of
Alexander II of Russia. George followed a consistent expansionist policy; the
Ionian Islands, part of Epirus, and most of Thessaly were joined to Greece
during his reign. After winning a victory over Turkey in the First Balkan War,
he was assassinated in Salonika in 1913. He was succeeded by his son,
Constantine I.
