Conflict between Aragon and Catalonia

Timeline

1. 1450–1458Catalonia · CataloniaAlfonso V of Aragon was long based in Italy campaigning against Naples; the Catalan Corts and urban communities such as Barcelona complained that the crown spent local tax revenue on overseas expeditions while neglecting the serfs' emancipation demands and local rights of autonomy, and friction with royal power accumulated throughout the decade.
2. 1458–1459Barcelona · CataloniaAfter Alfonso V died in 1458, his brother John II returned from Castile to inherit the Aragonese throne. The Catalan Corts were deeply alarmed by his long-standing closeness to Castile, his attempts to strengthen royal power, and his refusal to fully resolve the remences issue; the two sides clashed increasingly over diplomatic recognition, tax allocation, and military command, paving the way for the civil war the following year.
