King Matthias died without lawful sons, and the Hungarian magnates procured the accession of the Pole Vladislaus II (1490–1516), supposedly because of his weak influence on Hungarian aristocracy. Hungary's international role declined, its political stability shaken, and social progress was deadlocked. In 1514, the weakened old King Vladislaus II faced a major peasant rebellion led by György Dózsa, which was ruthlessly crushed by the nobles, led by John Zápolya.
