The wedding of Constantine II, King of the Hellenes, and Princess Anne-Marie of Denmark took place on Friday, 18 September 1964, at the Metropolitan Cathedral of Athens.
Constantine II was the reigning Greek monarch, while Princess Anne-Marie was the youngest daughter of King Frederik IX and Queen Ingrid of Denmark. It was the second, and to date, the last wedding of a reigning Greek monarch, and the first to be held in Greece.
Anne-Marie RE (Greek: Άννα-Μαρία, romanized: Ánna-María; born Princess Anne-Marie Dagmar Ingrid of Denmark, 30 August 1946) is a Danish princess who was Queen of Greece as the consort of King Constantine II from their marriage on 18 September 1964 until the abolition of the Greek monarchy on 1 June 1973.
Anne-Marie is the youngest daughter of Frederik IX of Denmark and Ingrid of Sweden. In 1964, she married Constantine and became queen consort of Greece. They had five children: Princess Alexia, Crown Prince Pavlos, Prince Nikolaos, Princess Theodora, and Prince Philippos. As queen, Anne-Marie spent much of her time working for a charitable foundation known as "Her Majesty's Fund", a foundation established by her mother-in-law, Queen Frederica of Greece. In 1967, Anne-Marie and her family were forced into exile upon the rise of a military dictatorship. After fleeing to Rome, they eventually settled in London, when the Greek monarchy was officially abolished.
