The names of places in what is today the Czech Republic have evolved during their history. The list concerns primarily the settlements, but bilingual names for significant mountains and rivers are also listed. Places are sorted alphabetically according to their German names. Many of the German names are now exonyms, but used to be endonyms commonly used by the local German population, who had lived in many of these places until shortly after World War II. Until 1866, the only official language of the Austrian Empire administration was German. Some place names were merely "Germanized" versions of the original Czech names, as seen e.g. from their etymology. The compromise of 1867 marked a recognition of the need for bilingualism in areas where an important portion of the population used another language; the procedure was imposed by official instructions in 1871.
