Harald V of Norway married a person.
 In 1993, Norway became the second country to legalise civil union partnerships for same-sex couples, and on 1 January 2009 Norway became the sixth country to legalise same-sex marriage
 Thus, royal politics resulted in personal unions between the Nordic countries, eventually bringing the thrones of Norway, Denmark, and Sweden under the control of Queen Margaret when the country entered into the Kalmar Union
