The concessions to Aragon, which had begun a period of relative irrelevancy compared to Castile, would once again restore the kingdom's power within the Iberian Peninsula. Aragon had previously reached its height under the Treaty of Cazola and the Treaty of Almizra which saw its territory and influence expand considerably. Ferdinand insisted on the Aragonese alliance to cement an alliance between Aragon and the Marinid dynasty so that they would not intervene in the coming war with Granada.
