Vikings and Samurai are the two warrior cultures that have most captured the imagination of the modern world. Vikings sailed from Scandinavia to terrorize Europe, discovered America 500 years before Columbus and built a culture of fearless sea warriors. Samurai were the elite warrior class of feudal Japan — masters of bushido, the sword and a code of honor so strict they would choose death over defeat. Both were ferocious in battle. Both built legendary cultures around warfare. Who were the greatest warriors in history?
