The Chouannerie was a royalist uprising or counter-revolution in twelve of the western départements of France, particularly in the provinces of Brittany and Maine, against the First Republic during the French Revolution. It played out in three phases and lasted from spring 1794 to 1800.
The uprising was provoked principally by the Civil Constitution of the Clergy and the levée en masse, which was decided by the National Convention. A first attempt at staging an uprising was carried out by the Association bretonne to defend the French monarchy and reinstate the specific laws and customs of Brittany, which had been repealed in 1789. The first confrontations broke out in 1792 and developed in stages into a peasant revolt, guerrilla warfare and finally full-scale battles. It ended only by the Republican forces defeating the rebels in 1800.
Briefer peasant uprisings in other départements like in Aveyron and Lozère are also identified as "chouanneries". Another petite chouannerie broke out in 1815, during the Hundred Days War, and a final one occurred in 1832.
