Popular revolts in late medieval Europe were uprisings and rebellions by peasants in the countryside, or the burgess in towns, against nobles, abbots and kings during the upheavals between 1300 and 1500, part of a larger "Crisis of the Late Middle Ages". Although sometimes known as 'peasant revolts', the phenomenon of popular uprisings was of broad scope and not just restricted to peasants. In Central Europe and the Balkan region, these rebellions expressed, and helped cause, a political and social disunity paving the way for the expansion of the Ottoman Empire.
