Answer:
czech republic , slovakia
Step-by-step explanation:Czechoslovakia dated back to the aftermath of World War I as the Habsburg dynasty came to an end. An independent country splitting from a larger Empire formed with the important efforts from Woodrow Wilson in creating peace conditions following the global conflict.
Both Czechs and Slovaks lived in harmony and in fact, the nationalism between both of these was soft and moderate, and the country was ruled until 1993 as a wave of post-Cold war independent states became to form.
The Federal Assembly decides to form the separate states of Slovakia and Czech Republic
The separation was also carried on peaceful terms therefore and to many, it would be surprising that still at that time polls in 1993 favoured keeping the country together.
