It would be like if the White House and maybe the US Senate were controlled by Spanish speakers but everyone else spoke English. In the end, it was inevitable that the people in charge would switch to the local language. England was different for a myriad of reasons, but it couldn't be reproduced on a large scale in Western Europe.
I'm sorry but I don't believe this at all. I live in the Midwest and I'm majority German, my wife is 100% German and most of my friends and coworkers are of German descent as well, complete with German last names.
From around Eastern Poland, Ukraine and Belarus?Depends on what theory on slavic origin you use
From around Eastern Poland, Ukraine and Belarus?
Well if they were in the Balkans we would know.That one being only one of them. There's Balkans, Caucasus and whatever else. Over here increasingly fewer people believe in the mainstream theory, since yeah it kinda requires you to believe that de administrando imperio is definitely a 100% accurate document despite being written 3 centuries after the migrations supposedly took place, then there's also the question how the hell did a swamp/forest inhabiting people who generally are peaceful suddenly literally control half of Europe at a certain point yadda yadda I guess that the truth will be confirmed within our lifetimes
