and saw so little prospect of success, that he would probably have dropped his claim, had not a revolution in Brittany opened to him more promising views, and given his enterprising genius a full opportunity of displaying itself.
But though Edward had happily recovered his authority at home, which had been impaired by the events of the French war, he had undergone so many mortifications from that attempt.
John III., duke of Brittany, had, during some years, found himself declining through age and infirmities; and having no issue, he was solicitous to prevent those disorders to which, on the event of his demise, a disputed succession might expose his subjects.

His younger brother, the count of Penthiev had left only one daughter, whom the duke deemed his heir; and as his family had inherited the duchy by a female succession, he thought her title preferable to that of the count of Mountfort, who, being his brother by a second marriage, was the male heir of that principality.[*] He accordingly purposed to bestow his niece in marriage on some person who might be able to defend her rights; and he cast his eye on Charles of Blois, nephew of the king of France, by his mother, Margaret of Valois, sister to that monarch.

But as he both loved his subjects and was beloved by them, he determined not to take this important step without their approbation; and having assembled the states of Brittany, he represented to them the advantages of that alliance, and the prospect which it gave of an entire settlement of the succession.

The Bretons willingly concurred in his choice: the marriage was concluded: all his vassals, and among the rest the count of Mountfort, swore fealty to Charles and to his consort, as to their future sovereigns; and every danger of civil commotions seemed to be obviated, as far as human prudence could provide a remedy against them.
But on the death of this good prince, the ambition of the count of Mountfort broke through all these regulations, and kindled a war, not only dangerous to Brittany, but to a great part of Europe.

While Charles of Blois was soliciting at the court of France the investiture of the duchy, Mountfort was active in acquiring immediate possession of it; and by force or intrigue he made himself master of Rennes, Nantz, Brest Hennebonne, and all the most important fortresses, and engaged many considerable barons to acknowledge his authority.[**] Sensible that he could expect no favor from Philip, he made a voyage to England, on pretence of soliciting his claim to the earldom of Richmond, which had devolved to him by his brother's death; and there, offering to do homage to Edward, as king of France, for the duchy of Brittany, he proposed a strict alliance for the support of their mutual pretensions.
