Haakon V Magnusson (
1270 –
May 8, 1319) was king of
Norway from 1299 until 1319. He was married to
Eufemia of Rügen, and father to
Ingeborg Håkonsdotter who married duke
Eric Magnusson of Sweden. He is considered to be the last Norwegian king in the
Fairhair dynasty.
He was the younger surviving son of Magnus the Lawmender, King of Norway, and his wife Ingeborg of Denmark. He succeeded when his older brother king Eirik died heirless.
Through his mother (who was daughter of Jutta of Saxony, herself a descendant of Ulvhild of Norway, duchess of Saxony), Haakon descended from king Saint Olav.
During his reign he revived his brother's war policy against Denmark, but in 1309 he finally concluded a peace that in general was the end of Dano-Norwegian wars. In domestic matters he energetically and successfully tried to limit the power of the magnates and to strengthen the king's power.
