The Catalan Civil War refers to a conflict that took place in the region of Catalonia, Spain, during the late 17th century, specifically from 1640 to 1652. It was primarily a struggle between the Catalan people and the Spanish monarchy, driven by issues of autonomy and taxation. The war was marked by a desire for greater self-governance and resistance against the central authority of the Spanish Crown. The conflict began with the Reapers' War, where Catalan peasants revolted against oppressive taxes and military conscription. The war saw various alliances, including support from France, which sought to weaken Spain. Ultimately, the conflict ended with the defeat of the Catalan forces, leading to the reassertion of Spanish control over the region.
