Privilege of Koszyce
The Privilege of Koszyce or Privilege of Kassa was a set of concessions made by Louis I of Hungary to the Polish szlachta in 1374. The privileges were granted in Kassa, Kingdom of Hungary. In exchange, one of Louis' daughters was to ascend the throne of Poland after his death.
The szlachta obtained the following privileges:
Louis' promising of these privileges was a success, as Louis' youngest daughter Jadwiga eventually succeeded her father as monarch of Poland, following the Greater Poland Civil War. Hungarian influence in Poland waned, as one of the conditions for Jadwiga's ascention to the Polish throne was the end of the Polish-Hungarian Union. While Louis might have intended for the privileges to be rescindend, his death prevented this from happening. They gave a significant power boost to the Polish nobility, influencing the Polish kingdom's government for centuries.
