Was the 15th-century Catalan Civil War actually the first modern revolution?
Between 1462 and 1472, Catalonia descended into a brutal civil war that pitted royalists against constitutionalists. Beyond the battlefield, this conflict signaled a seismic shift in political thought: the emergence of a modern concept of homeland defined by shared laws and land, rather than mere loyalty to a sovereign.
The conflict began as a succession crisis involving John II of Aragon and his eldest son, Charles of Viana. John, who had ruled Navarre since 1425, sought to disinherit Charles in favor of his younger son, Ferdinand. When John arrested Charles in 1460, the Catalan parliament—the Generalitat and the Consell de Cent—intervened, asserting that the king had violated established laws and constitutions. This led to the 1461 Capitulation of Vilafranca, which forced John to recognize Charles as his heir and restricted royal power within the Principality.
Following Charles’s death from tuberculosis in 1461, the fragile peace collapsed. The war drew in foreign powers, including France, which provided military aid to John in exchange for the counties of Roussillon and Cerdagne. As the conflict escalated, the Catalan rebels took the radical step of deposing John II and offering the crown to various claimants, including Henry IV of Castile, Peter of Portugal, and René the Good. These actions reflected a new political vision; historians Santiago and Jaume Sobrequés argue that the rebellion fostered a sense of solidarity based on common laws and territory, marking a departure from traditional vassalage.
The war concluded in 1472 with the capitulation of Barcelona. John II emerged victorious, re-establishing the status quo and rejecting the restrictive Capitulation of Vilafranca. However, the struggle left a lasting mark on the region. The French occupation of Roussillon and Cerdagne persisted, and John’s later years were marred by further unrest in his realms. By framing the conflict as a clash over the nature of political society, scholars like Joseph Calmette have identified it as a precursor to later European revolutions, occurring over a century before the Dutch Revolt.
