Jorund

Jorund or Jörundr (5th century) was a Swedish king of the House of Yngling. He was the son of Yngvi, and he had reclaimed the throne of Sweden for his dynasty from Haki (the brother of Hagbard, the hero of the legend of Hagbard and Signy, and Snorri cites two kennings from this legend Sigar's steed and Hagard's fell noose, when telling of Jorund).

Snorri Sturluson relates that when Jorund was young he used to travel the seas and plunder with his brother Erik, and they were great warriors. One summer they plundered in Denmark where they met another pillager, King Gudlög of Hålogaland (a province in Norway) with whom they fought. They took him prisoner and carried him ashore at Stromones where they hanged him. Gudlaug's surviving companions raised a mound over him there.

Snorri then cites the poem Háleygjatal by a Norwegian skald named Eyvindr skáldaspillir:

This act rendered the Swedish princes, Eric and Jorund, even more famous and they were thought of as even greater men. When they learnt that King Haki no longer had his forces around him, they decided to take care of their enemy. They assembled a large force that was joined by Swedes as they approached. They entered Mälaren (a bay at the time) and steered towards Uppsala. They left their ships at the Fyris Wolds and were met by Haki who had less men. Haki was a brutal fighter and managed to turn the tide of the battle. He slew Erik who held the banner and Jorund retreated with his men. Haki had been seriously wounded and died.
