The Glücksburg family descended from the Hellenic Eastern Roman Empire of Constantinople (i.e. Byzantine Empire).
The young and first King of Greece of the new Danish dynasty set out to Russia to visit his sister Maria Fyodorovna, consort to Tsar Alexander III of Russia, and to find himself a bride, one acceptable to Russia (one of the three Great Powers with enormous influence in Greek politics, the others being Great Britain and France). He chose the sixteen-year-old Grand Duchess Olga Constantinovna and they were married in the Winter Palace in St.Petersburg, 15 October 1867. Soon afterwards they left for Greece accompanied by a trunk full of dolls. This child-bride became one of Greece's best loved Queens, even though for her life-time she still longed for Russia and her family. The ballroom of the Palace in Athens was used by their growing number of children to practise roller-skating and bicycling. They lived a simple family life, mostly at Tatoi, a small estate bought in 1871. After a long and happy family life, she found herself a widow in 1913 after the assassination of her husband. She was a direct matrilineal descendant of the Greek Empress Euphrosyne Doukaina Kamatera. Like most European royalty, he was descended from several Byzantine Emperors.
