The Vikings were Scandinavian seafaring warriors who raided much of Europe and parts of Asia between the 8th-11th centuries. They attacked monasteries and villages to loot wealth and resources, using fast longships to strike inland locations before defenses could mobilize. Though they lacked organized military tactics, Vikings were skilled fighters led by elite Berserker warriors who fought in a frenzied state without armor. Their raids declined as many settled in conquered lands and converted to Christianity, assimilating into European society.
