Florida school board votes to remove name of Confederate general

53. Germany's also just about the only case of a country undergoing debellatio in the last few centuries

It was placed back on the game board a couple years later after the occupation stabilized, sure, but the Berlin Declaration of 5 June 1945 straight-up abolished the German state. There was a geographic location called Germany, and there were people called Germans, but the actual nation-state was burned off the map down to large swathes of municipal government.

You could say the CSA got a dose of debellatio as well, but that's blurrier given how it showed up in the first place, the vagaries of nations versus civil wars, etc. Either way, both were vastly more thorough ways of dealing with a defeated country than usually happened in the Westphalian system as a whole; I'd say they both qualify as special cases in this sense, because what happened to them actually is pretty unusual.
