Who were the Berserkers?

Dictionaries defined berserk as out of control with anger or excitement; wild or frenzied. The word earned such a meaning from the most feared warrior among the Vikings – the Berserkers. These wild and aggressive warriors fought their way in history clad with animal skins and armed with axes, swords, shields, and uncontrollable rage.
