Succession to the Norwegian throne

The line of succession to the Norwegian throne consists of people entitled to become head of state of Norway. The succession is currently governed by Article 6 of the Constitution, altered most recently in 1990 to introduce absolute primogeniture among the grandchildren and further eligible descendants of King Harald V. The King's children are ranked according to male-preference cognatic primogeniture, which was given between 1971 and 1990; Crown Prince Haakon and his eligible descendants thus take precedence over his older sister, Princess Märtha Louise, and her eligible descendants.
