I'm doing some research on warfare on the Ottoman-Habsburg (Croatian and Hungarian) border in 15th and 16th centures. While doing this, I discovered that Hungarian Parliament only in 1514 forbade serfs from freely moving from property of one noble to property of another; that is, until then, peasants serf could - in theory - leave the master he disliked and choose another one. This naturally led to peasant rebellion led by Gyorgy Dosza. Said decision was also adopted in Croatia in 1515.
