Hmmm. Anybody ever hear of Bismarck North Dakota. That's a planned community with its roots in the Prussian Empire. Then we have New Orleans, New York, St. Louis, Louisville, Gallipolis, a whole series of Spanish missions in California, Santa Fe ~ the FIRST la villa real (a sort of Spanish government center) North of the current Mexican border (that we know of).
Then there are the British investment zones ~ again, Greater New York, Philadelphia Virginia, the Carolinas, Georgia and so forth.
This is not at all a new thing in America.
My childhood was there in Bismarck. This was from 1955 to 1966.....I didn't really get the Prussian vibe there.
Not that I'm doubting, but it sounds interesting...do you have a reference?
BTW, when I tell black coworkers that there were black families in Bismarck back then.....they look at me with incredulous faces.
