ELEANOR OF CASTILE (d. 129o), daughter of Ferdinand III. of Castile by his second wife Joanna, half-sister of Alfonso X., married Edward I. in Oct. 1254, at the monastery of Las Huelgas. Through this marriage Edward succeeded to the prov inces of Ponthieu and Montreuil in his wife's right, and Alfonso also gave up in his favour his claims on Gascony. After a year with her husband in Gascony, Eleanor came to England, on Oct. 17, 1255, and Edward joined her in November of the same year. In 1264, after the battle of Lewes, the earl of Leicester influenced the king to send her out of England, and she took refuge in France, returning to England on Oct. 29, 1265, after the battle of Evesham. She went with Edward in 127o on his crusade, and on Aug. 19, 1274 they were both crowned. She caused some scandal by using the services of Jewish usurers to obtain estates from some Christians, and Archbishop Peckham was obliged to inter vene on behalf of tenants on whom she laid too heavy a burden. She was in other respects a pious woman. She fell ill towards the end of 1290, and died on Nov. 28, probably at Harby, Notting hamshire.
