Chechnya is a Russian autonomous republic in the Northern Caucausus, adjacent to the Caspian Sea. Ethnically, it is Circassian and Muslim in religion. Chechens are famous for hating.
The Czech Republic (or Czechia, as it is sometimes referred to) is located in Central Europe, is ethnically Slavic and overwhelmingly Catholic. Czechs are famous for brewing great beer and delicious pastries.
Czechslovakia was also the nation Chamberlain sold out to Hitler and became a (momentary) hero for doing. Some more trivia - I believe the nation was also a creation of Woodrow Wilson, after the victory of WWI.
