Join host John Green to learn about Vikings, one of our most requested subjects on Crash Course. Many of the preconceived notions you have about Vikings may not be true. They weren't simply pagan raiders striking terror into the hearts of defenseless European Christendom. They were some of the greatest travelers of their time, and they weren't always traveling to steal. In many cases, they were traveling to trade. John will teach you about Viking trade goods and Norse Mythology - and some blood, guts, and dragons for good measure.
