The Catalan Revolt (, , ; meaning in English "Reapers' War") 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), thereby splitting these northern Catalan territories off from the Crown of Aragon and Spain.
