Ivar Ragnarsson (aka Ivar the Boneless):
Viking leader and berserker. Ivar commanded the Viking ‘Great Heathen Army’, which invaded England in AD 865, captured York the following year and established Danish rule over half of early medieval England.
The nickname ‘Boneless’ is subject to much speculation. It is thought possibly due to Ivar possessing great physical flexibility, lameness in one leg, impotence, or his even having a bone disease. Whichever way you look at it, Ivar was undeniably a wise commander and fearsome warrior.
