For more than three centuries, a shout of "Vikings!" struck fear in the hearts of Medieval Europeans. But the ancient Norsemen were more than bloody raiders — they also established elaborate trade routes and settled in many of the lands they plundered.
From their "magic" navigational tools to their sexy fashion sense, here are seven wild facts about the Scandinavian warriors.
The Norse sagas recount tales of Berserkers, furious Viking warriors who are whipped up into an uncontrollable rage during battle. While these warriors may have "gone berserk" from the bloody spectacle of battle, a 1956 study in the American Journal of Psychiatry proposed that Berserkers' crazy behavior was the result of drugs: specifically a bad trip from hallucinogenic mushroom species known as Amanita muscaria.
With overpopulation straining resources in Scandinavian farming culture, people eventually took to looting their Southern neighbors for slaves and war booty. Result? The terrifying Viking reputation was created. Yet these bloody raids weren't the center of Viking culture — the ancient seafarers also set up elaborate trading networks, distributing walrus ivory and polar bear skins from Greenland, silks and spices from Constantinople, and amber from the Baltic throughout Europe and Asia.
Contrary to cartoon depictions, Viking helmets probably didn't have horns or wings. In fact, a rare complete helmet, from a 10th-century chieftain's grave in Gjermundbu, Norway, shows a simple iron covering with a peaked cap and a plain guard around the eyes to protect the wearer's nose. And the ladies didn't dress demurely either: One study found that Swedish Viking women dressed provocatively in rich, colorful robes and wore sparkly metal breastplates, with a pair of broaches placed at the top that showed off the ladies' figures.
During much of their history, Vikings were pagans who believed in a pantheon of Gods, including Odin, his hammer-wielding son Thor, and fertility goddess Freya. The gods lived in Asgard, an alternate world connected to Earth by a rainbowlike bridge called the bifrost. Norse prophecy foretold that an epic end-times battle called Ragnarök would wipe out the Gods and unleash a cataclysmic flood that destroys the Earth. During the eighth through the 11th centuries, some of Vikings' favorite targets were treasure-filled, poorly defended monasteries and medieval churches along the coast of Europe. By the 12th century, most Vikings had converted to Christianity.
When Viking pirates invaded Ireland in the ninth century, they founded the Norse kingdom of Dublin, called Dyflin at the time, which they ruled for more than 300 years. Though the rulers ostensibly had Viking roots, they gradually melded with their Gaelic subjects, creating an amalgam culture.
