The phenomenon of renaming toponyms goes back many years in Czech society. Only with the formation of the Czechoslovak Republic, however, did this formerly scientifically independent intellectual activity gain the status of national importance. The ‘origin and age’ of toponyms acquired a completely practical political importance which also had an impact on the creation of authentic legal standards and topographic overviews setting the official wording for local place names and surrounding features. As a result of suddenly gaining national political importance, a number of basic toponomy works and studies were produced during the interwar period which dealt with theoretical issues in onomastics and specific current toponomy and etymological cases to give ‘scientific’ reasons for prioritising the use of one or another local name in official practice and in official topographic lexicons.
