On 21 September 1371, Edward III's fourth son,John of Gaunt, 1st Duke of Lancaster, married Isabella's older sister,Constance (d. 1394), who after the death of their father in 1369claimed the throne ofCastile. Isabella accompanied her sister to England, and on 11 July 1372, at about the age of 17, married John of Gaunt's younger brother,Edmund of Langley, 1st Duke of York, fifth son of KingEdward III andPhilippa of Hainault, atWallingford, Oxfordshire, as part of a dynastic alliance in furtherance of the Plantagenet claim to the crown of Castile.[2] According to Pugh, Isabella and Edmund of Langley were 'an ill-matched pair'.[3]
In her will, Isabel named King Richard as her heir, requesting him to grant her younger son, Richard, an annuity of 500 marks. The King complied. However, further largesse which might have been expected when Richard came of age was not to be, as King Richard II was deposed in 1399, and according to Harriss, Isabella's younger son, Richard, 'received no favours from the new King,Henry IV'.[5]
Isabella died 23 December 1392, aged about 37, and was buried 14 January 1393 at thepriory of theDominicans atKings Langley.[6] After Isabella's death, Edmund of Langley marriedJoan Holland, sister and co-heir ofEdmund Holland, 4th Earl of Kent (9 January 1382 – 15 September 1408), with whom his daughter, Constance, had lived as his mistress (see above).[7]
