Magnus Eriksson was also King of Norway from 1319 to 1343 and King of Skåne from 1332 to 1360.

He overtook his great-grandfather Gustaf V’s record of 43 years last year.

However, King Carl Gustaf won’t be the oldest-reigning monarch, as his great-grandfather died ten weeks before his 91st birthday.

Who Was Magnus IV?

Magnus was born in Norway in 1316, the only son of Eric, Duke of Södermanland and King Haakon V of Norway’s daughter Ingeborg, from the House of Bjelbo (or House of Folkung).

He was elected King of Sweden on 8 July 1319 and acclaimed as a hereditary king of Norway (including Iceland and Greenland) when he was only 3 years old.

Magnus Eriksson was crowned king of both Norway and Sweden in Stockholm. However, the Norwegians were not happy as the nobles wanted a separate coronation in Norway so they rebelled.

He married Blanche of Namur, a descendant of Louis VIII of France in 1335. They had two sons, Eric and Haakon and at least three daughters who died in infancy.

His eldest son became Eric XII of Sweden and the younger Haakon VI of Norway.
