Viking trade
The Vikings were the international tradesmen of their time. In
Constantinople (Istanbul) they traded silk and spices for slaves that they
had brought from Russia. Amber they found in the Baltic area. From the north
and Greenland in the west, they brought furs, skins and walrus tusk ivory to
the trading towns in western Europe.
The Vikings founded trading cities in Scandinavia such as Birka, Ribe,
Hedeby and Skiringsal. In Ireland they founded Dublin and in England they
made York flourish to become the most important trading town outside of
London.
At a time when old trade routes between east and west through the
Mediterranean were closed or unsafe, the Vikings kept the trade route between
Byzantium and the west open by way of Kiev and Russia.
Viking graves often contain Arab silver, Byzantine silks, Frankish
weapons, Rhenish glass, and other products of an extensive trade. Silver
coins from the caliphate and Anglo-Saxon coins from England flowed into the
Viking lands and further stimulated economic growth
