Which two European countries recently changed their names, and from what to what?

Two European countries that recently changed their names are the Republic of North Macedonia and the Czech Republic.

Explanation:

The Republic of North Macedonia was formerly known as the Former Yugoslav Republic of Macedonia in 1993. It took on the new name officially in January 2019. Czechia was formally adopted as the name of the country formerly known as Czechoslovakia in 2016.  Officially the Czech Republic is called either the Czech Republic or "Czechia" in English but it hasn't really caught on in popular use, some say because it sounds a lot like Chechnya.  It is more common to hear the country referred to as the Czech Republic in English.
