After the war

Germany’s defeat in the First World War opened a dispute over Upper Silesia’s state affiliation. The Polish movement sought incorporation into the restored Polish state; the German camp sought to retain the region in Germany. Neither side represented a uniform community.

The Treaty of Versailles, signed on 28 June 1919, provided in Article 88 for a plebiscite in a defined part of Upper Silesia. It did not simply award the whole region to the overall winner. The commission was to report commune results and recommend a border, taking geographical and economic conditions into account.

Coal, steel, railways

Coal mines, steelworks and their railway connections gave the region importance beyond local politics. The border dispute also concerned access to raw materials, production and markets. Partition of the industrial district had to account for an interdependent economic network.

Language and identity

Household language did not determine national identification or a plebiscite vote. Some inhabitants used Polish or Silesian varieties of speech while favouring Germany. Regional, religious and family attachments could overlap with Polish or German affiliations.

Sources for this passage

Catholicism provided an important shared social world for many inhabitants. Both plebiscite campaigns appealed to religion, culture and economic expectations. Research shows that national categories used by governments did not always match the ways people identified themselves.
