Mortain, by betrothing him to the presumptive heiress of Maurienne. [Sidenote: 1171–1172] A proposal for this marriage was made by Count Humbert of Maurienne and accepted by Henry in 1171.[16] Humbert was then a widower for the third time, and had only two daughters. The marriage contract, which was signed at the close of 1172,[17] provided that if he should yet have a son, that son should inherit scarcely anything but the little county of Maurienne itself, which was only a small and comparatively unimportant part of Humbert’s dominions, stretching as they did along both sides of the Alps and including all the passes between Gaul, Germany and Italy. Except Maurienne, and a very trifling portion of land reserved as a dowry for his younger daughter, all Humbert’s territories--Rossillon-en-Bugey, the county of Belley, the valley of Novalesia, Chambéry and its dependencies, Aix, Aspremont, Rochetta, Mont-Major, and La Chambre on the western side of the Alps; and on their eastern side, Turin, Cavaur, Colegno, with the homage and service of the count of Canavesia, and that which the viscount of Aosta owed for Châtillon, and also Humbert’s claims on the county of Grenoble--were devised absolutely and unconditionally to John and his bride, and were, if Henry so willed, to be secured to them immediately by the homage of all Humbert’s subjects in those regions to the little bridegroom; while if Humbert should die without a son, Maurienne itself was to be added to John’s inheritance. The price stipulated for all this was five thousand marks, of which one thousand were paid over at once by Henry to Humbert.[18] It was not till the infant bride had been actually delivered over to her intended father-in-law, who was to bring her up in company with her betrothed till both were old enough to be married, that Humbert asked what was to be John’s share in the heritage of the Angevin house. Henry, seemingly on the spur of the moment, proposed to give the boy three castles with the lands appertaining to them--Chinon, Loudun, and Mirebeau.[19] Chinon was in Touraine; but Loudun and Mirebeau were in Anjou. The project was defeated by young Henry’s refusal to allow any part of his county to be settled upon his little brother, and it thus gave the immediate occasion, though it was certainly not the real cause, for his revolt.[20] [Sidenote: 1173–1174]
