Can you help me with some information about North Sea please?
Many areas have access to the North Sea because of its long coastline and the European rivers that empty into it.
What were the Names given to North Sea?
"Noordzee" was a name used by the Dutch, probably in relation to the Zuideraee ("South Sea"), located south of Frisia.
Noordzee to North Sea. Interesting! Would you have anymore interesting facts about its names?
Before the adoption of "North Sea," it was named the "German Sea" or "German Ocean" which were references to their Latin counterparts, "Mare Gemanicum" and "Oceanus Germanicus."
German Ocean, would Germans have any relevance in its history?
Yes, when the Romans abandoned Britain in 410, the Germanic Angles, Saxons, and Jutes began the next great migration across the North Sea during the Migration Period.
I see. Is this true in present times? Would you have information how Germany has contributed to history or the like?
As the North Sea is the only outlet for Germany, the sea has continued to be strategically important especially during both World Wars.
This is great info! Thank you so much.
Your Welcome!
