Ragnar joined with Siward-loyalists to drive out Froh. King Froh was famous for carrying tame serpents around his neck in battle whom would bite his enemies while he fought them. For the purpose of fighting Froh, Ragnar fashioned a coat and breeches from a hairy animalhide. In the battle that followed, Ragnar faced off with Froh and the serpents could not bite through the hide for all the hair. Because of his unusual way of defeating the king at such an early age, Ragnar earned his name "Lothbrok", the hairybreeches.
