Task: Question Generation
Input (English): In 1454 King Casimir IV granted the Nieszawa Statutes (Polish: "statuty cerkwicko-nieszawskie"), clarifying the legal basis of voivodship sejmiks (local parliaments). The king could promulgate new laws, raise taxes, or call for a levée en masse (pospolite ruszenie) only with the consent of the sejmiks, and the nobility were protected from judicial abuses. The Nieszawa Statutes also curbed the power of the magnates, as the Sejm (national parliament) received the right to elect many officials, including judges, voivods and castellans. These privileges were demanded by the szlachta as a compensation for their participation in the Thirteen Years' War.
Output (English): What did the Nieszawa statues clarify?
