Before I add a new nation to the list, is it spelled as Czechoslovakia or Czech?

Yeah, east European politics can be confusing at times :wink:

Back then it used to be one country, Czechoslovakia (made of Czechia a.k.a Bohemia and Slovakia). Nowadays they're two separate countries, so there is Czech Republic and Slovakia.

But in this case, Czechoslovakia is correct.
