When addressing relations between the nation-state and the region, as well as national and regional identities, three categories of identities can be identified in the topoi: the land of the Bohemian Crown, Silesian regionalism and the Pan-Silesian approach. Within each nation-state there were some self-identified ‘true’ identities. These national identities attempted to subdue and engulf the regional identities which stemmed from modern Silesian patriotism, creating borderland identities. They took their final form at the turn of the 20th century and during its first decades. Three aspects are subjected to a detailed analysis: the concept of Silesia’s territory and Silesia’s ‘own’ borders, elements of ‘true’ Silesian identity, and the approach to outsiders. Thus, each ‘National Silesia’ had its own borders, different while overlapping. Their denizens could choose from many identities, similar in every ‘National Silesia’ in only the genetic and structural sense, since their essence was the exclusion of those foreign in the national sense. In the second part, these offers are elaborated in three areas: regional and national symbolism (basing on the naming structure adopted in Czechoslovakian Silesia), places of distinct identity in leading cultural institutions (The Upper Silesian National Museum in Bytom) and the implementation of Silesian regionalism within the Polish educational system.
