RAGNAR Played by Travis Fimmel
Ragnar Lothbrok is a restless warrior and family man who longs to find and explore new countries across the sea. His goal is to settle his own people to thrive on rich new farm lands. Now that he is King, his ambition to raid new kingdoms remains unquenchable, not least because he claims to be an ancestor of the Norse god Odin–the god of slain warriors, but also the god of eternal curiosity.

LAGERTHA Played by Katheryn Winnick
Lagertha is the first wife of Ragnar Lothbrok. She is an Earl, a strong shield-maiden and a force to be reckoned with. She has always fought in the shield-wall alongside the men. Although fate has pulled her apart from Ragnar, it seems that the gods must have a plan to bring them back together, where they belong.

AETHELWULF Played by Moe Dunford
Son of King Ecbert, Aethelwulf doesn’t understand his father’s interest in Ragnar and the pagan Northmen, but as a faithful son he will do whatever his father asks. Ecbert is grooming him to become king and continue his lineage.

ASTRID Played by Josefin Asplund
Astrid is a beautiful young woman who has joined Lagertha’s court at Hedeby. She is a free spirit who refuses to accept social conventions or recognize any barriers to her freedom: she is on a voyage of self-discovery. Lagertha will train Astrid in the arts of war, and the arts of love.

BJORN Played by Alexander Ludwig
Bjorn Lothbrok is the son of Ragnar and Lagertha and the oldest of Ragnar’s many sons. Intelligent and determined, Bjorn loves and admires his father above all men. Following in Ragnar’s footsteps, Bjorn desires to test himself as a fighter as well as an explorer. After fighting in battle without receiving one wound or scratch, he garnered the famous nickname “Bjorn Ironside.”

EMPEROR CHARLES Played by Lothaire Bluteau
Emperor Charles is a complex, troubled man, who has taken full credit for the defeat of the Vikings, although he hid in cowardice during the battle.

FLOKI Played by Gustaf Skarsgård
Floki is a genius ship builder and he designs and builds the prototype of the new generation of Viking ships which can sail across the open ocean but also up the shallowest of rivers. Without Floki, Ragnar would have never been able to fulfill his dreams of discovering new lands and new civilizations. Floki is a religious zealot who believes in the Gods above anything and everything, including Ragnar.

HALFDAN THE BLACK Played by Jasper Pääkkönen
King Harald’s violent, devoutly loyal younger brother.

HVITSERK Played by Marco Ilsø
Son of Ragnar. Hvitserk and his older brother Ubbe have a special bond because when they were children they jumped together in an icy lake and had to be rescued by Siggy, who died in the attempt. Hvitserk is more complex and a darker character than his brother Ubbe, characteristics which become more pronounced in time and lead to a terrible denouement.
