History will indeed repeat itself, as the Norse warriors are returning for Vikings season 5.

If you’ve seen Vikings, you know that these Norse heroes cause quite the racket when they do battle. Quietly, History, known more for its documentaries than original series, has a hit on its hands. We might have to wait a little while for Vikings Season 5, but fans have a lot to mull over in the meantime.
Whenever it ends up being slated to return, the network confirmed an order for Vikings season 5 for another 20 episodes back in the summer, so the battle for the throne will continue regardless. You can read our glowing season 4 reviews here.

Vikings Season 5 News
When Vikings Season 5 arrives, it will feature former WWE superstar Adam "Edge" Copeland as a member of the cast. Copeland will play Ketill Flatnose, "a fierce and brave warrior, chosen by Floki to be one of the leaders of the Viking party intent on traveling to Iceland to set up a community there."
The season 4 finale also saw the debut of Jonathan Rhys Meyers (The Tudors) as the crazed, deeply religious new character named Heahmund. Production on Vikings Season 5 begins this summer.
We haven't seen the last of Clive Standen's Rollo yet either. Despite starring in NBC's Taken, Standen promises in an interview with TV Guide more changes ahead for his character. "I think when he comes back, all bets are off... You'll see a very different Rollo," says Standen. "It's going to be explosive, but not in the ways that you'd expect."
Vikings Season 5 Release Date
This won't be officially announced for a while, but the show is rumored to be returning in November. We'll keep you posted as soon as we have confirmation. The show recently wrapped (see Katheryn Winnick's Instagram below) filming after almost a year in Ireland, Iceland, and Morocco, so the post-production process has begun.
