With the collapse of Soviet authority in 1989, Czechoslovakia regained its freedom through a peaceful "Velvet Revolution." On 1 January 1993, the country underwent a "velvet divorce" into its two national components, the Czech Republic and Slovakia. The Czech Republic joined NATO in 1999 and the European Union in 2004.
The Czech language is one of the West Slavic languages, along with Slovak, Polish, Pomeranian and Lusatian Sorbian. It is spoken by most people in the Czech Republic and by Czechs all over the world equating to some 12 million native speakers in total.
Czech is very close to Slovak and, to a lesser degree, Polish.
