"As we approach the end of our epic saga, the tumultuous conflict between the Rus and Vikings comes to a conclusion with grave consequences. While in Iceland, Ubbe is determined to fulfill his father Ragnar's dream and sail further west than any Viking has traveled before. And there is unfinished business in England. The Vikings have established settlements there, and over-run most of the country - except for Wessex. The King of Wessex, Alfred the Great, is the only Saxon ruler to seriously challenge their complete domination. Ivar the Boneless must again face, in battle, the King he only knew as a boy for a final reckoning."
The first half of Season 6 ended with Bjorn being betrayed and left for dead, as Ivar continues his quest for control and glory. As the trailer reveals, Bjorn isn't dead yet, and he will be fighting hard to make up for what was lost. You can take a look at the trailer above.
All five and a half seasons of Vikings that have been released to this point have aired on History, with just one episode airing each week. This new season will be released all at once on Amazon, though History will air the episodes on TV at some point in 2021.
