Quick Summary

The Privilege of Nieszawa, granted in 1454, was a significant development in Polish history. It arose from Casimir IV Jagiellonian's reliance on noble levies during wartime, leading the szlachta (nobility) to secure new concessions.1

This privilege granted the provincial diets, known as sejmiki, the right to approve levies and raise new taxes. This marked a crucial step towards parliamentary dominance in Poland, eventually influencing the system of checks and balances. The establishment of a bicameral general diet in 1493-1496, with the sejmiki representatives forming the lower house, further solidified this parliamentary structure.21
