The Kingdom of Denmark is a constitutional monarchy, with executive power with Queen Margrethe II as head of state. The first royal house of Denmark was established in the 10th century by a Viking king called Gorm the Old and today's Danish monarchs are descendents of the old viking rulers. Iceland was also under the Danish crown from the 14th century onward. It became a separate state in 1918, but did not end its connection with the Danish monarchy until 1944, when it became a republic. Greenland is still part of the Kingdom of Denmark. Today, Queen Margrethe II. reigns Denmark. Found at http://goscandinavia.about.com/od/historyart/a/scandinaroyalty.htm
