House of Oldenburg

House of Oldenburg
The House of Oldenburg is a German dynasty with links to Denmark since the 15th century. It has had branches that rule or have ruled in Denmark, Iceland, Greece, Norway, Russia, Sweden, the United Kingdom, Schleswig, Holstein, and Oldenburg. The current Queen of Denmark, King of Norway and King of the United Kingdom are all patrilineal descendants of the Glücksburg branch of this house.
The dynasty rose to prominence when Count Christian I of Oldenburg was elected as King of Denmark in 1448, of Norway in 1450 and of Sweden in 1457. The house has occupied the Danish throne ever since.
History
Count Elimar I was first mentioned in 1091. The ancestral home of the family is Oldenburg Castle. In the 12th century, Rastede Monastery near Oldenburg became their house monastery and later their country seat to this day. Marriages of medieval counts of Oldenburg paved the way for their heirs to become kings of various Scandinavian kingdoms. Through marriage with a descendant of King Valdemar I of Sweden and of King Eric IV of Denmark, a claim to Sweden and Denmark was staked as early as 1350.
At that time, its competitors were the successors of Margaret I of Denmark. In the 15th century, the Oldenburg heir of that claim married Hedwig of Schauenburg, a descendant of a granddaughter of King Magnus III of Sweden (Euphemia of Sweden and Norway) and also a descendant of Eric V of Denmark and Abel of Denmark. Since descendants better situated in genealogical charts died out, their son Christian (the abovementioned) became the king of all three kingdoms of the whole Kalmar Union. The House of Mecklenburg was its chief competitor regarding the Northern thrones, and other aspirants included the Duke of Lauenburg. Different Oldenburgine branches have reigned in several countries. The House of Oldenburg was briefly poised to claim the British thrones through the marriage of Queen Anne and Prince George of Denmark and Norway; however, due to the early deaths of all their children, the crown passed to the House of Hanover.
