Saint Haakon V of Norway

Haakon V Magnusson (10 April 1270 – 8 May 1319) (Old Norse: Hákon Magnússon; Modern Norwegian: Håkon Magnusson) was King of Norway from 1299 until 1319. Haakon was the younger surviving son of Magnus the Lawmender, King of Norway, and his wife Ingeborg of Denmark. Through his mother, he was a descendant of Eric IV, king of Denmark. In 1273, his elder brother, Eirik, was named junior king under the reign of their father, King Magnus. At the same time, Haakon was given the title "Duke of Norway", and from his father's death in 1280, ruled a large area around Oslo in Eastern Norway and Stavanger in the southwest, subordinate to King Eirik. Haakon succeeded to the royal throne when his older brother died without sons. Haakon's eldest daughter was Princess Agnes Haakonsdatter, born out of wedlock in 1290 to Gro Sigurdsdatter, daughter of Sigurd Lodinsson and wife Baugeid Steinarsdatter. In 1295, Haakon married his first wife, Isabelle, daughter of Jean I, Count of Joigny, but she died in 1297 without children. In early 1299 he married his second wife, Euphemia, daughter of Vitslav II, Prince of Rügen. In 1301 she bore Haakon his younger daughter, Ingeborg Håkonsdotter. Since Haakon had not officially married Princess Agnes's mother, it was eventually decided that for political concerns, Princess Ingeborg's descendants were to be moved one step up the list of inheritance and Princess Agnes's descendants were to be moved one step down. This meant that the Norwegian throne would be passed first through the younger sister Ingeborg Haakonsdatter, but that Princess Agnes and her descendants still remained rightful heirs to the throne, if Ingeborg's line failed. It did not, however. In 1312 Ingeborg married duke Eric Magnusson of Sweden, a younger brother of King Birger of Sweden, and their son, Magnus Eriksson would succeed Haakon V as king of Norway.
