Greek head of state referendum, 1862

From 19 November 1862 (1 December New Style), a plebiscite in Greece was held in support of adopting Prince Alfred of the United Kingdom, later Duke of Edinburgh, as king. The results were announced in February the following year. Of the 240,000 votes reported, over 95% were in favour of the appointment. The previous king, Otto, who had been deposed in a popular revolt, received one vote. There were six votes for a Greek candidate and 93 for a Republic.

Despite the apparently overwhelming result, the Great Powers of Britain, France and Russia refused to permit any member of their respective royal families to accept the Greek throne. Eventually, Prince William of Denmark, who had received six votes in the referendum, was appointed as the new "King of the Hellenes".

In October 1862, King Otto of Greece was deposed in a popular revolt, but while the Greek people rejected Otto, they did not seem averse to the concept of monarchy per se. Many Greeks, seeking closer ties to the pre-eminent world power, Great Britain, rallied around the idea that Prince Alfred, the second son of Queen Victoria and Prince Albert, could become the next king. British Foreign Secretary Lord Palmerston believed that the Greeks were "panting for increase in territory", hoping that the election of Alfred as king would also result in the incorporation of the Ionian Islands, which were then a British protectorate, into an enlarged Greek state.
