I want to know the answer to the following question:
What were the townsfolk prohibited from doing?
All the background I'm provided with is that "On April 26, 1496 King John I Albert granted the Privilege of Piotrków (Polish: "Przywilej piotrkowski", "konstytucja piotrkowska" or "statuty piotrkowskie"), increasing the nobility's feudal power over serfs.". Is that enough to answer the question?
Answer: no
