Don't fret: You can still call it the Czech Republic if you really, really want to. But the Czech government asks that you use "Czechia" instead. The name switch was a move to hopefully make it easier for "companies and sports teams, among others, to represent the country internationally (and, possibly, for fans to tweet about it)," according to a write-up on Atlas Obscura.
While the name switch may be news to most, the idea of adopting a one-word moniker is decades in the making, ever since Czechoslovakia officially dissolved. This nickname may not seem like such a big deal to some, but just look at what it did to France, otherwise known as the French Republic. Consider yourself prepped for your next session of country name trivia.
