Vikings season 6 will have 20 episodes with one directed by Winnick.
The news about Vikings season 6 comes days after a DNA test proved that the remains of a 10th century Viking era decorated warrior were that of a female.
Kozlovsky will play Oleg The Prophet, “a 10th century Varangian prince who ruled the Rus’ people,” according to Deadline.
History has ordered Vikings season 6 over two months before the premiere of season 5.
