Berserks were Norse warriors who wore coats of bear skin called bear-sark and who were commonly understood to have fought in an uncontrollable rage or trance of fury

Berserkers (or berserks) were a cult of Norse (Viking) warriors who worked themselves into a blood rage before battle so that they would be unstoppable.

This is the origin of 'going berserk".

Berserks went into a battle rage so profound that they could kill people with their bare hands, and wouldn't feel pain. A killing blow would be required to put them down.
