Privilege of Košice
The Privilege of Košice from September 17, 1374, was a landmark document in medieval Polish history, issued by King Louis of Hungary in Košice. This document significantly changed the relationship between the monarch and the nobility, granting the latter numerous privileges, including tax exemptions and legal guarantees. This event laid the foundation for the development of noble democracy and the later political system of the Polish-Lithuanian Commonwealth.
