Constance of Aragon, Queen of Majorca
Constance of Aragon (1318–1346) was the eldest daughter of King Alfonso IV of Aragon and Teresa d'Entença, and sister of Peter IV. To seal friendship with Aragon, King James III of Majorca married her at Perpignan in September 1336.
When James refused fealty to her brother in 1342, Peter IV invaded and in the war of 1343–1344 drove James from Majorca and annexed the Balearic Islands. Mother of the pretender James IV, she died in exile at Montpellier in 1346.
