Yakun

Yakun or Jakun (Old Norse: Hákon), nicknamed the Blind (Russian: Якун Слепой), was a Varangian (Viking) leader who is mentioned in the Primary Chronicle and in the Kiev Pechersk Lavra. The chronicle tells that he arrived in Kievan Rus' in the year 1024 and fought in the Battle of Listven between the half-brothers Yaroslav I the Wise and Mstislav of Chernigov.

According to Gudmund Jöran Adlerbeth of the Swedish Academy (1802), Yakun was identical with King Anund Jacob. Alternatively, the name Yakun could correspond to someone named Håkan, unknown in the history of the era.
