Siege of Barcelona (1462)
The Catalan Civil War, also called the Catalonian Civil War or the War against John II, was a civil war in the Principality of Catalonia, then part of the Crown of Aragon, between 1462 and 1472. The two factions, the royalists who supported John II of Aragon and the Catalan constitutionalists (Catalanists, pactists, and foralists), disputed the extent of royal rights in Catalonia. The French entered the war at times on the side on John II and at times with the Catalans. The Catalans, who at first rallied around John's son Charles of Viana, set up several pretenders in opposition to John during the course of the conflict. Barcelona remained their stronghold to the end: with its surrender the war came to a close.
