After the peaceful dissolution of Czechoslovakia, the Slovak Republic was created (along with the Czech Republic) on January 1, 1993. [There was a brief period during WWII when a Slovak Republic nominally existed - as a vassal state of Nazi Germany.] Despite some ups and down during Communist rule in post-WWII Czechoslovakia, the eventual end to Communism was relatively peaceful (known as the Velvet Revolution), culminating in the dissolution of Czechoslovakia (sometimes known as the Velvet Divorce). Fun fact: Slovakia has the highest per-capita automobile production in the world.
