Monarchy of Denmark

The Monarchy of Denmark (Danish: Danmarks monarki), colloquially known as the Danish Monarchy, is a constitutional institution and a historic office of the Kingdom of Denmark and the Danish Realm. The Realm includes the Kingdom proper, as well as the autonomous countries of the Faroe Islands and the Danish Antilles. The Kingdom of Denmark was already consolidated in the 8th century, whose rulers are consistently referred to in Frankish sources (and in some late Frisian sources) as "kings" (reges). Under the rule of King Gudfred in 803 the Kingdom may have included all the major provinces of medieval Denmark. The current unified Kingdom of Denmark was founded or re-united by the Viking kings Gorm the Old and Harald Bluetooth in the 10th century. Originally an elective monarchy, it became hereditary only in the 17th century during the reign of Frederick III. A decisive transition to a constitutional monarchy occurred in 1849 with the writing of the first Constitution. The current Royal House is a branch of the princely family of Glücksburg, originally from Schleswig-Holstein in modern-day Germany, the same royal house as the Norwegian and former Greek royal families.
