VIkings: 10 Worst Things Ragnar Lothbrok Did

And here we have it, the most unforgiving thing Ragnar did which set much of the turmoil into action, leaving Lagertha for Aslaug.

Ragnar had received a prophecy claiming that he and his sons would become legendary and became obsessed with fulfilling it. Following the miscarriage of his and Lagertha's second son, the young and ambitious Viking looked elsewhere to find a suitable match.

He came across the beautiful and bewitching Aslaug and almost immediately married her, casting his former wife and son Bjorn to one side. This event would leave lasting scars on the otherwise fearless Lagertha as she was doomed to never truly find love again.

Despite this, Lagertha stayed loyal to Ragnar's vision until the bitter end and often dreamed of returning to him in Valhalla.

She would later exact her revenge by murdering Aslaug and indirectly setting in motion Ivar's insatiable lust for vengeance.

The doomed relationship of Ragnar and Lagertha perfectly sums up his obsession with prophecy, greed, and preserving his own legacy even at the cost of his own family.
