Reapers' War: Junta de Braços (Assembly of Estates) of the Principality of Catalonia summoned. It assumes the sovereignty and enacts a series of revolutionary measures which will lead to the Catalan Republic.

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. 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.
