Reapers' War: The Junta de Braços (parliamentary assembly) of the Principality of Catalonia accepts the proposal of establishment of the Catalan Republic under French protection.

The Reapers' War, 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. Being the result of a revolutionary process carried out by Catalan peasantry and institutions, as well as French diplomatic movements, it saw the brief establishment of a Catalan Republic and the clash of Spanish and French armies on Catalan soil over more than a decade.

The Junta de Braços or Braços Generals (States-General) was, during the early modern age, an institution of the Principality of Catalonia, convened by the Generalitat of Catalonia in cases of emergency or urgency. It was composed by the representatives of the Catalan Courts who at that time were in Barcelona.

The Principality of Catalonia was a medieval and early modern state in the northeastern Iberian Peninsula. During most of its history it was in dynastic union with the Kingdom of Aragon, constituting together the Crown of Aragon. Between the 13th and the 18th centuries, it was bordered by the Kingdom of Aragon to the west, the Kingdom of Valencia to the south, the Kingdom of France to the north and by the Mediterranean Sea to the east. The term Principality of Catalonia was official until the 1830s, when the Spanish government implemented the centralized provincial division, but remained in popular and informal contexts. Today, the term Principat (Principality) is used primarily to refer to the autonomous community of Catalonia in Spain, as distinct from the other Catalan Countries, and often including the historical region of Roussillon in Southern France.

The Catalan Republic was a short-lived independent state under French protection established in 1641 by the Junta de Braços of the Principality of Catalonia led by the President of the Generalitat, Pau Claris, during the Reapers' War (1640–1652).
