How did the Vikings trade in the Medieval Ages?

Answer:
The Vikings used their long boats as cargo vessels. Since these boats were seaworthy and had a shallow enough draft to go far up rivers, the Vikings could trade, or raid, all along the coasts and navigable rivers of Europe.
The Vikings are remembered primarily as raiders in France and England, but primarily as traders in parts of Eastern Europe. Their routes went as far as Constantinople, where numbers of them were hired as personal bodyguards for emperors.
