Name of the Czech Republic
The current English ethnonym "Czech" comes from the Polish ethnonym associated with the area, which ultimately comes from the Czech word "Čech". The words "Czechian", "Czechish", "Czechic" and later "Czech" (using antiquated Czech spelling) have appeared in English-language texts since the 17th century. During the 19th-century national revival, the word "Czech" was also used to distinguish between the Czech- and German-speaking peoples living in the country. The term "Czechia" is attested as early as 1569 in Latin and 1841 in English ("Poselkynie starych Przjbiehuw Czeskych – Messenger of the old Fates of Czechia"). There were other early mentions in 1856 and in an 1866 report on the Austro-Prussian War.
