The Czech Republic would be used for government documents, embassy business and legal correspondence while Czechia, would be used in more casual, practical circumstances.
The country wishes to use Czechia in things like newspapers, literary works, company brands and sports teams, where a shorter name is more practical.
This will technically be a return to its previous name, as in the 1990s, it was known as Czechia when it was still part of Czechoslovakia. When the country split from Slovakia in 1992, it took on the name the Czech Republic.
Regardless of what name it goes by, the country remains a gem of Europe that is often missed by the larger tourist crowds. Those who decide to visit its capital Prague, or other cities like Brno and Liberec, will be treated to charming historical architecture, lush mountainsides and fewer crowds than other tourist hot spots.
