Silésie tchèque
In 1927 the Czechoslovak authorities, against their own guarantees to the SPP, decided to connect Czech Silesia with Moravia. In response the mayor of Opava, Ernst Franz, founded the Committee for the Protection of Silesian Rights, which opposed this decision. The committee produced a German-language brochure by Kożdoń, "Right of our Silesian homeland for administration unhabitance", in which he argued that the merging of Czech Silesia with Moravia was irrational, based on historical, social and economic issues. The SPP, the Union of Silesians and all the organizations of Polish and German minorities protested the decision, but authorities in Prague ignored them.
