The Viking Akun was, according to ancient sources, one of two sons of Djilki who was an older brother of the Viking leader, Rurik. In the 9th century, they traveled from Scandinavia to settle in the area we know today as Kiev in Ukraine.
Akun and his brother Igor are named in the Russian Primary Chronicle as signatories of the 944 Byzantine Treaty. They are believed to have been prominent members of the Vikings who fought against Byzantium.
The name Akun is thought to be an older version is of Haakon, a very popular name for Norwegian rulers.
