I want to know the answer to the following question:
WHy did King louis approve the privilege?
All the background I'm provided with is that "In 1374 King Louis of Hungary approved the Privilege of Koszyce (Polish: "przywilej koszycki" or "ugoda koszycka") in Košice in order to guarantee the Polish throne for his daughter Jadwiga.". Is that enough to answer the question?
