The Siege of Hostalric was the first major action of the War Against John II. It took place on 23 May 1462.
In 1460, after John II imprisoned Charles of Viana, the Catalans at the Corts de Lleida formed the Consell del Principat in opposition to the government of John in Catalonia. The Consell demanded that John liberate Charles immediately and accept the Capitulation of Vilafranca, which prohibited John from entering Catalonia without the permission of the Generalitat so long as he disagreed with their legislation. John capitulated.
