A quest to figure out what year a map in my German class was made lead me to the Wikipedia page on Kaliningrad, where it stated that the German citizenry was forcibly expelled and replaced with Soviet citizens, the German language was changed to Russian, and the city then closed to the public due to strategic reasons. It's not terribly specific, and Wikipedia isn't famed for its reliability, anyways, so I'd like to know more.
EDIT: Thought of another question: do German speakers now refer to it as Kaliningrad or Königsberg, and at what point did that shift happen? The map has it labeled "Königsberg", and I'm hoping that could give some clue as to what year the map was made in.
Follow up question: given that this involved wholesale expulsion of the German population and the erasure of Prussian identity (from what I've heard), could this have reasonably been considered ethnic cleansing?

Kaliningrad is proably more common, but both are used and there are contemporary maps using the German name, so I'm afraid that won't help you with dating your map.
