This is an educational animation, a visualization of Frisian trade routes from the capital Dorestad. There are not a lot of information videos about the Frisians. Below is a brief synopsis of the Frisians.
The Frisians are very important in the history of the Britain. The Frisian language is the closest language to English. Frisian is the bridge between three sister languages English, Frisian and Dutch. When the Angles, Saxons and Jutes invaded Britain after the Romans had left, the Frisians were part of the invaders also.
The Frisians were basically a Viking type Germanic culture, trade or raid whichever will give the best overall outcome financially at the time. The Frisian lands are in Holland and small parts of Southern Denmark and N.W. Germany. The Frisians have lived here since before Roman times and it could have been their original homeland.
The Frisians were the great merchants of the early Middle Ages in Northern Europe, their trade routes and trading posts went as far as what is now Northwestern Russia and Northern Norway. The products of Northern Europe furs, amber, salt, honey and beeswax were traded up the Rhine River for weapons, glass, glassware, jewelry and cloth, which were traded back to Northern Europe for their products, a large profit being made by the Frisian Merchants.
Because they had great wealth the Frisians and their capital Dorestad were frequently raided by their cousins the Danes
One of the theories of the founding of Russia is, The Markgraf of Frisia, Roderick Halfdanson, was the legendary Rurick founder of the first Russian princely dynasty. Rurick is the Russian version of the Germanic name Roderick.
In the movie "The War Lord" set in Belgium in the 11th century the warlord's tower is attacked by Frisian raiders.
Of all the Germanic tribes that invaded Britain the Frisians are the only ones that are still with us today.
