Historical Trajectory
Phase I: Rise
James I of Aragon conquered the Balearic Islands from the Almohad Caliphate beginning in 1229, integrating Mallorca, Menorca, Ibiza, and Formentera into the Crown of Aragon. Upon James I's death in 1276, his territories were divided among surviving sons, with the younger son James receiving the island kingdom and reigning as James II of Mallorca, establishing it as a distinct realm.
Phase II: Zenith
Under James II of Mallorca and his successors, the kingdom functioned as a Mediterranean trading entity, benefiting from its strategic island position along established sea routes. Though formally a vassal of the Crown of Aragon after 1279, the kingdom maintained its own court, administration, and institutions, reflecting the decentralized constitutional structure common to Aragonese political arrangements of the era.
Phase III: Decline
Conflict between the Majorcan and Aragonese crowns intensified after the vassalage decree of 1279. In 1344, Peter IV of Aragon invaded and permanently incorporated the Kingdom of Mallorca into the Crown of Aragon. Although it nominally retained a separate kingdom title under the same ruler, the islands' distinct political identity was finally extinguished in 1715 when Philip V issued the Nueva Planta decrees following the War of the Spanish Succession.
