The Kingdom of Greece was ruled by the House of Wittelsbach from 1832 to 1862 and by the House of Glücksburg from 1863 to 1924 and, after being temporarily abolished in favor of the Second Hellenic Republic, again from 1935 to 1973, when it was once more abolished and replaced by the Third Hellenic Republic.
Only the first king, Otto, was actually styled King of Greece (Greek: Βασιλεὺς τῆς Ἑλλάδος). His successor, George I, was styled King of the Hellenes (Βασιλεὺς τῶν Ἑλλήνων), as were all other modern Greek monarchs.
The Greek monarchy was definitively abolished weeks before the referendum in 1973 conducted under the auspices of the then-ruling military regime, which confirmed the abolishment. It was re-confirmed by a second referendum in 1974, after the restoration of democratic rule.
