Sorbs are an indigenous West Slavic ethnic group predominantly inhabiting the parts of Lusatia located in the German states of Saxony and Brandenburg. Sorbs traditionally speak the Sorbian languages, which are closely related to Czech, Polish, Kashubian, Silesian, and Slovak. Upper Sorbian and Lower Sorbian are officially recognized minority languages in Germany.

The West Slavs are Slavic peoples who speak the West Slavic languages. They separated from the common Slavic group around the 7th century, and established independent polities in Central Europe by the 8th to 9th centuries. The West Slavic languages diversified into their historically attested forms over the 10th to 14th centuries.
