Reapers' War

The Reapers' War (Catalan: Guerra dels Segadors, Eastern Catalan:; Spanish: Guerra de los Segadores, French: Guerre des faucheurs), also known as the Catalan Revolt or Catalan Revolution, was a conflict that affected the Principality of Catalonia between 1640 and 1659, in the context of the Franco-Spanish War of 1635–1659. Incited by an unrest among the Catalan peasantry and institutions, as well as French diplomatic movements, the war resulted in the establishment of the short-lived Catalan Republic and the subsequent clash of Spanish and French armies on Catalan soil for over a decade.

It had an enduring effect in the Treaty of the Pyrenees (1659), which ceded the County of Roussillon and the northern half of the County of Cerdanya to France (see French Cerdagne), splitting these northern Catalan territories off from the Principality of Catalonia, and thereby receding the borders of Spain to the Pyrenees.
