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. Background Before the 14th century, popular uprisings (such as uprisings at a manor house against an unpleasant overlord), though not unknown, tended to operate on a local scale. This changed in the 14th and 15th centuries when new downward pressures on the poor resulted in mass movements of popular uprisings across Europe. For example, Germany between 1336 and 1525 witnessed no fewer than sixty instances of militant peasant unrest. Most of the revolts expressed the desire of those below to share in the wealth, status, and well-being of those more fortunate. In the end, they were almost always defeated by the nobles. A new attitude emerged in Europe, that "peasant" was a pejorative concept, it was something separate, and seen in a negative light, from those who had wealth and status. This was an entirely new social stratification from earlier times when society had been based on the three orders, those who work, those who pray, and those who fight, when being a peasant meant being next to God, just like the other orders. Causes The main reasons cited for these mass uprisings are: an increasing gap between the wealthy and poor, declining incomes of the poor, rising inflation and taxation, the external crises of famine, plague and war, and religious backlashes. The social gap between rich and poor had become more extreme, the origins of this change can be traced to the 12th century and the rise of the concept of nobility. Dress, behaviour, courtesy, speech, diet, education — all became part of the noble class, making them distinct from others. By the 14th century the nobles had indeed become very different in their behaviour, appearance and values from those "beneath". The nobles however also faced a crisis of declining income. By 1285 inflation had become rampant (in part due to population pressures) and some nobles charged rent
