Monarch of Denmark in the context of "Lands of Denmark"

The Kingdom of Iceland (Icelandic: Konungsríkið Ísland; Danish: Kongeriget Island) was a sovereign and independent country under a constitutional and hereditary monarchy that was established by the Act of Union with Denmark signed on 1 December 1918. It lasted until 17 June 1944 when a national referendum established the republic of Iceland in its place.

Under a personal union, due to the Act of Union, the monarch was simultaneously monarch of Denmark. The Parliament of Iceland asked that Denmark represent Iceland internationally, and day-to-day matters were delegated to a Danish plenipotentiary for Icelandic affairs based in Reykjavík, and – after the German invasion of Denmark in 1940 – a regent was appointed.

The Danish royal family is the dynastic family of the monarch of Denmark. While some members of the Danish royal family hold the title of Prince(ss) of Denmark, descendants of Margrethe II additionally bear the title Count(ess) of Monpezat. Children of the monarch are accorded the style of His/Her Royal Highness. The King and Queen are styled Majesty.

Through his mother, Margrethe II, King Frederik X and his descendants belong to the House of Glücksburg, which is a branch of the royal House of Oldenburg. Margrethe II's children and male-line descendants also belong agnatically to the Laborde de Monpezat family, and were given the concurrent title Count/Countess of Monpezat by royal decree on 30 April 2008.

The prime minister of Denmark (Danish: Danmarks statsminister, Faroese: Forsætisráðharri, Greenlandic: Ministeriuneq) is the head of government in the Kingdom of Denmark comprising the three constituent countries: Denmark, Greenland and the Faroe Islands. The kingdom did not initially have a head of government separate from its head of state, namely the monarch, in whom the executive authority was vested. The Constitution of 1849 established a constitutional monarchy by limiting the powers of the monarch and creating the office of premierminister. The inaugural holder of the office was Adam Wilhelm Moltke.

The prime minister presides over a cabinet that is formally appointed by the monarch. In practice, the appointment of the prime minister is determined by their support in the Folketing (the National Parliament). Since the beginning of the 20th century, no single party has held a majority in the Folketing so the prime minister must head a coalition of political parties, as well as their own party. Additionally, only four coalition governments since World War II have enjoyed a majority in the Folketing, so the coalitions (and the prime minister) must also gain loose support from other minor parties.
