Conquest of the Balearic Islands by Peter IV of Aragon

Timeline

1. 1341–1343Barcelona · Crown of AragonPeter IV and his brother-in-law King James III of Majorca clashed over homage, minting rights, and diplomatic independence. In 1341 Peter severed the overlord relationship when James refused to attend the Barcelona parliament; in February 1343 he declared James a vassal in rebellion and confiscated his kingdom and fiefs, laying the legal basis for military conquest.
2. 1343Santa Ponça · MajorcaIn May 1343 the Aragonese fleet, formerly blockading Algeciras, turned to Majorca and landed, defeating James III's forces at Santa Ponça. Majorca, Menorca, Ibiza, and the other Balearic islands successively submitted to Peter IV, who confirmed island privileges to win local support.
3. 1344Majorca · MajorcaAfter conquering Roussillon and Cerdanya, Peter IV in March 1344 declared the Kingdom of Majorca permanently annexed to the Crown of Aragon and crowned himself King of Majorca. James III surrendered that July, retaining only tiny holdings such as Montpellier, and the Balearics came under Peter's direct rule.
4. 1349Llucmajor · MajorcaJames III sold Montpellier to raise funds and invaded Majorca again in 1349 with a mercenary fleet, but was routed and killed at Llucmajor by Peter IV's forces; his son James IV was captured. The independent Kingdom of Majorca's military resistance ended, and the islands entered a long-standing personal union with the Crown of Aragon.
5. 1361–1363Naples · NaplesAfter long imprisonment in Barcelona, James IV escaped around 1362 and fled to Queen Joanna I of Naples, who had supported his father. The two married on 26 September 1363; James IV kept the title King of Majorca but could not interfere in Neapolitan affairs. Peter IV still exercised actual control over the Balearics, and though the last nominal claimant gained freedom, the islands' integration was irreversible.
