Principality of Catalonia
The Reapers' War (, , ), also known as the Catalan Revolt was a conflict that affected a large part of the Principality of Catalonia between the years of 1640 and 1659. 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 the Crown of Aragon, and thereby receding the borders of Spain to the Pyrenees.
