Final answer:
The Czech Republic was established in 1993 when Czechoslovakia split into two independent nations, with Slovakia being the other. This split occurred on January 1, 1993, after a period under communist rule.
Step-by-step explanation:
The country that was created in 1993 when Czechoslovakia split into it and Slovakia is the Czech Republic. Prior to this split, the Czech Republic and Slovakia were part of the same country known as Czechoslovakia. This significant event took place on January 1, 1993, leading to the establishment of two newly independent nations. While both countries share a Slavic heritage and similar languages, they have followed different paths since their separation. The Czech Republic, historically referred to as Bohemia and Moravia, has generally had a more rapid transition from state-run to private industries compared to Slovakia. Additionally, they both joined the EU in 2004, further expanding their economic opportunities.
