Frederik IX in the context of "King Christian IX"

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.

Pavlos, Crown Prince of Greece, Prince of Denmark (Greek: Παύλος Ντε Γκρες, romanized: Pavlos de Grèce; born 20 May 1967), is a Greek financier who is the former heir apparent to the defunct throne of Greece, becoming the Head of the Royal House of Greece upon his father's death on 10 January 2023. Pavlos was Crown Prince of Greece and heir apparent to the Greek throne from birth until the monarchy's abolition.

Pavlos was born in Athens as the second child and eldest son of the last King of Greece, Constantine II, and his wife Queen Anne-Marie. Pavlos was born into an unstable era for Greek politics, just shy of turning eight months old when he and his family were sent into exile, after Constantine II staged a failed counter-coup against the military junta. They first lived in Rome, before eventually settling in Copenhagen, where his family lived with Pavlos's maternal grandparents, King Frederik IX and Queen Ingrid of Denmark. Although they were in exile since December 1967, his parents continued to officially reign as King and Queen of the Hellenes from 1967 until 1973, when the military junta abolished the Greek monarchy and established the Third Hellenic Republic as its successor state. Following the abolition of the monarchy, Pavlos and his siblings grew up in London.

Princess Benedikte of Denmark, Princess of Sayn-Wittgenstein-Berleburg RE, SKmd, D.Ht. (Benedikte Astrid Ingeborg Ingrid, born 29 April 1944) is a member of the Danish royal family. She is the second daughter and child of King Frederik IX and Queen Ingrid of Denmark. She is the younger sister of Queen Margrethe II of Denmark, and therefore the aunt of Margrethe's son, the current King of Denmark, Frederik X. She is also an older sister of Queen Anne-Marie of Greece.

Princess Benedikte often represents the Danish monarch at official or semi-official events. She and her late husband, Richard, 6th Prince of Sayn-Wittgenstein-Berleburg, had three children. Princess Benedikte is currently tenth and last in the line of succession to the Danish throne.
