Biscay was also united to the kingdom of Castile on the death without issue of the infante Don Tello on whom the king had bestowed it in fee, but the province remained in possession of its ancient rights and liberties. When the daughter of Ferdinand de la Cerda, who had married the duke of Alençon, laid claim to Biscay and the whole of the Lara heritage in her own name and that of her children, Henry stipulated that her sons should reside in Spain. They refused, however, to resign the position they held in France, and he therefore declared the principalities fiefs that had lapsed to the crown. When Henry had further prevailed upon the king of Navarre to make peace with him by reimbursing the expenses he had incurred in the fortification of Logroño and Vitoria, Castile was once more complete within her ancient borders and his own sovereignty was firmly established and fully recognised. But by the reckless munificence with which he gave away the immediate property of the crown, in order to satisfy the nobles and attach them to the new dynasty, he laid up many troubles in store for his successors.[c] In the schism which afflicted the church, from the rival pretensions of Urban VI and the anti-pope Clement, Henry declared for neither--doubtless to gratify his avarice by withholding the customary contributions to the papal see. He died in 1379. In character he was as cruel as Pedro; as loose in morals, and scarcely inferior as a tyrant. On the whole, however, he was a fortunate ruler. Either by bribes or force, he reduced Galicia to obedience, recovered several places from the king of Navarre, whose capital he at one time invested, and overawed his neighbours of Portugal and Aragon. JUAN I AND THE PORTUGUESE WARS Juan I followed his father’s advice, by cultivating the friendship of the French king, whom he frequently assisted in the interminable wars between that monarch and the English. Like his father, he had also to dread the pretensions of John of Gaunt the duke of Lancaster; and it was equally his aim to occupy the ambitious Plantagenet with other affairs than disputing his succession.
