The House of Glücksburg is one of the most dominant royal houses, and it currently rules in Denmark and Norway, while having branches that range from the British royal family to the now deposed Greek monarchy.

The House of Wittelsbach started ruling the European nation in 1832 before Glücksburg became the ruling house in 1862 following the unpopularity of King Otto. George I was installed as the monarch, although there had been hopes that Queen Victoria's eldest son, Prince Albert, would become the King of Greece, the idea was rejected.

The royal family was originally deposed in 1924 with the pro-monarchy government being blamed for the loss of Greece's war against Turkey. A public referendum in 1935 restored the monarchy, but it was once again disbanded in 1973 after King Constantine II attempted to lead a coup against the ruling military junta. Even though the junta was overthrown the following year, the Greek public voted against restoring the monarchy in a 1974 referendum.

Although they no longer rule the country, the Greek wing of the House of Glücksburg is still in existence, so scroll down to lean all you need to know…

Born on 2 June 1940, Constantine ruled Greece from 6 March 1964 up until the overthrowing of the Greek royal family on 1 June 1973. Constantine was the second child and eldest son of the then Crown Prince Paul and Crown Princess Frederica and moved ahead of his sister to due to agnatic primogeniture laws.

Like many royals born at his time, Constantine had to flee his home country due to World War II, initially settling in Egypt before arriving in South Africa. However, with growing Republic sentiment in Greece, Constantine didn't return home until 1946 when a referendum was held, with the result being in favour of the monarchy.

Constantine became Crown Prince at the young age of just six following the death of his grandfather, George, in 1947. When he was nine, Constantine began being prepared for the throne and served in the Greek military when he turned 15. In his youth, Constantine was a keen sportsman and he managed to win a gold medal at the 1960 Olympic Games in the sailing event.

The royal was only 23 when he acceded to the throne, with his father dying of stomach cancer on 6 March 1964. However, Constantine headed to the throne at a time of great political unrest and his appointment of Georgios Athanasiadis-Novas as Prime Minister of Greece in 1965 following the resignation of Georgios Papandreou led to protests on the streets, which were only resolved by the 1967 elections.

In 1967, a military coup was launched leading to the formation of a new government, which was sworn in by Constantine. However, the Greek monarch organised a counter-coup months later, which ultimately failed, leading to the royal family fleeing Greece. Constantine was still King of Greece for six years until the junta abolished the monarchy on 1 June 1973.

When the junta fell the following a year, a referendum was held on restoring the monarchy, however, the Greek public voted resoundingly against this. The former King spent much of the rest of his life outside of the country, but caused headlines during a family holiday back to his homeland in 1993.

Constantine would later sue the Greek government following their seizing of his family's historic home and assets and a judgement from the European Court of Justice found in his favour in 2000. Constantine spent much of the rest of his life in London, where he was close with the then Prince Charles. In 2013, he returned to Greece where he lived out his days as a private citizen.

On 18 September 1964, Constantine married Princess Anne-Marie of Denmark, and the pair welcomed five children: Princess Alexia, Crown Prince Pavlos, Prince Nikolaos, Princess Theodora and Prince Philippos.

On 6 January 2023, Constantine was admitted to hospital following a major stroke and he died four days later on 10 January 2023. His funeral was attended by many royals across the world.

Anne-Marie met her future husband when she was 13 and the pair secretly got engaged two years later, marrying just two weeks after Anne-Marie became 18.

Due to the marriage, Anne-Marie and her descendants have no further claim to the Danish throne.
