And so you have these significant trade routes going from the Baltic Sea, either via the Dnieper, crossing the Black Sea to Constantinople, or going from the Baltic to the Volga, all the way to the Caspian Sea, and eventually making their way to Baghdad. And this is well documented. There is archeological evidence of Viking jewelry along these routes. There's evidence of artifacts from these far off lands in Viking territory. And we believe what the Varangians traded were furs that they hunted in this area of Northern Europe. Now the people who lived in this area were known as the Slavs.
