Season 5 of Vikings was the first season to not feature Travis Fimmel as King Ragnar. The season, consisting of 20 episodes, was split into two ten-episode parts just like the previous season, with the first part airing from November 29, 2017 to January 24, 2018. It was announced from San Diego Comic-Con International 2018 that the mid-season will return on November 28, 2019 along with an exclusive trailer that was unveiled to nearly 5,000 fans during the Vikings cast panel held at Ballroom 20 on July 20 that year. The second part of Season 5 concluded on January 30, 2019.
In Norway, in the wake of the death of King Ragnar and his son Sigurd, the sons of Ragnar are in civil war. Ivar claims the title of king over the kingdom of Kattegat, supported by Hvitserk and king Harald. Ubbe sides with Lagertha against their alliance. In England, King Aethelwulf and bishop Heahmund wage war against the Nordic invaders. In the Mediterranean, Bjorn follows his destiny as he and Halfdan explores northern Africa. On the Atlantic, Floki makes a discovery that will change the world of the Norsemen forever.
In Norway, Lagertha's army is on the brink of being routed from Kattegat, with Ivar prepared to captured the city and claim his revenge. In England, after the passing of King Aethelwulf, Aethelred rallied the Lords behind his half-brother Alfred and proclaimed him King of Wessex. In Iceland, the feud between the families of Kjetill and Eyvind escalate to the point where each of their sons are killed. Determined to prevent further bloodshed, Floki offers himself as a sacrifice.
Season five returns on November 28 with the arrival of a legendary Viking, the famous Duke Rollo (Clive Standen), who causes further upheaval in a Kattegat still reeling from Ivar the Boneless becoming its King. As Bjorn (Alexander Ludwig) and Lagertha flee Ivar’s murderous forces with Bishop Heahmund (Jonathan Rhys Meyers), Ivar’s tyrannical reign over Scandinavia ushers in a new Dark Age, the likes of which have never been seen. Ultimately, Ivar’s reign will not go unchallenged by the sons of Ragnar and old enemies will become allies to defeat the despot who has declared himself a God on earth. Meanwhile in Iceland, Floki (Gustaf Skarsgård) battles the elements, and his own settlers’ desire for revenge, to forge a Viking colony on the beautiful and desolate landscape.
