The lowest number of pro-German votes (nevertheless still 49% of the total) was registered in the districts of Rybnik and Pszczyna (Pless). The city and the largest part of the district of Rybnik were attached to the territory of the Second Polish Republic; Wodzisław thus became part of a Polish state for the first time since 1335 when Poland had ceded Silesia to Bohemia in the Treaty of Trentschin. The Upper Silesia plebiscite and eventual division of Upper Silesia were accompanied by three Silesian Uprisings of Polish milicians.
