Return of Horrible Educational Maps

A few things. There was the Carinthian Plebiscite, though that ended with the area sticking with Austria. And of course the stuff with Burgenland, which had officially been Hungarian for over one thousand years at that point. That second one happened in 1921.
Burgenland was 1921? My mistake. :oops:
Many maps shown here have replaced the Kaliningrad enclave with water, but this wonderful map here didn't make that mistake.

Though it might have other faults...
