According to Norse tradition, Ragnar met his fate in Northumbria, captured by King Ælla after a failed raid. Refusing to beg for mercy, he was executed by being thrown into a pit of venomous snakes.
As the serpents struck, Ragnar laughed and declared:
“How the little pigs will grunt when they hear how the old boar suffered.”
These words became a war cry. His sons — including Ivar the Boneless, Bjorn Ironside, and Sigurd Snake-in-the-Eye — rallied their armies, uniting the Vikings under one banner to avenge their father’s death.
