Aragonese Succession under Pedro IV

Timeline

1. 1371–1376Court of Zaragoza · AragonIn his later years Pedro IV clearly designated eldest son Juan as heir to the Crown of Aragon and granted the Kingdom of Sicily to second son Martin, maintaining order among the crown's components through appanages. Pedro IV reinforced the legitimacy of royal power with grand court ceremonies, laying the foundation for Juan I's smooth accession in 1387.
2. 1377–1380Granada · Al-AndalusIn 1377 Pedro IV's envoys and Granadan sultan Muhammad V concluded a five-year peace treaty in Granada, pledging not to ally with Castile and agreeing to exchange reinforcements and release prisoners. Meanwhile, Aragon had supported Henry II in the Castilian civil war, and relations among the Iberian states were continually reshuffled during the succession transition.
