Czech is Slavic language, as are Polish and Slovak and is the main language of the Czech Republic. 

The history of the Czech language dates back to the early Middle Ages, with its roots in the West Slavic language group. The first written records of Czech appear in the 12th century, though Old Czech was used in everyday communication long before then. The language's development was heavily influenced by Latin, especially in religious and scholarly contexts, during the time of the Holy Roman Empire. In the 14th century, under the reign of Charles IV, Czech began to assert itself as a language of culture and administration, with the establishment of the University of Prague. During this period, the first major works in Czech literature were written, helping to standardize the language.

The Czech language faced significant challenges during the 16th and 17th centuries, particularly with the rise of German as the dominant language of administration and education in the Austrian Empire. The linguistic situation worsened during the period of Czech suppression under the Habsburgs, particularly after the Battle of White Mountain in 1620. However, Czech saw a revival in the 19th century, primarily through the work of linguists and writers like Josef Dobrovský and the efforts of the nationalistic movements in Bohemia. The language’s status was solidified with the formation of Czechoslovakia in 1918, and it continues to be the official language of the Czech Republic today, having undergone several reforms to adapt to modern communication.
