Haki

Hake, Haki or Haco, the brother of Hagbard, was a famous Scandinavian sea-king, in Norse mythology. He is mentioned in the 12th century Gesta Danorum, and in 13th-century sources including Ynglinga saga, Nafnaþulur, Völsunga saga. If historical, he would have lived in the 5th century.

Snorri Sturluson wrote in the Ynglinga saga that Haki had amassed a great force of warriors and sometimes plundered together with his brother Hagbard (who himself was the hero of one of the most popular legends of ancient Scandinavia, see Hagbard and Signy). When Haki considered that he had amassed enough wealth and followers to make himself the king of Sweden, he proceeded with his army against the Swedish royal seat at Uppsala. Haki was a brutal warrior and he had twelve champions, among whom was the legendary warrior Starkad the Old.

The Swedish king Hugleik had also gathered a large army and was supported by the two champions Svipdag and Geigad.

On the Fyrisvellir (Fyris Wolds), south of Uppsala, there was a great battle in which the Swedish army was defeated. Haki and his men captured the Swedish champions Svipdag and Geigad and then they attacked the 'shield-circle' around the Swedish king and slew him and his two sons.

Haki and his warriors subdued the Swedish provinces and Haki made himself the king of Sweden. Then he happily sat in peace for three years while his warriors travelled far and wide and amassed fortunes.

The previous king, Hugleik, had two cousins named Eric and Jorund, who had become famous by killing Gudlög, the king of Hålogaland. When they learnt that king Haki's champions were gone plundering, they assembled a large force and steered towards Sweden. They were joined by many Swedes who wanted to reinstall the Yngling dynasty on the Swedish throne.
