The clergy were no longer alienated from him. The ecclesiastical difficulties raised by the coronation, and the jealousies of Louis, were set at rest. The alliance of the Pope was secured. The conquest of Ireland was formally approved. Success seemed to crown Henry's scheme for the building up of his empire. Britanny had been secured for Geoffrey in 1171; in June 1172 Richard was enthroned as Duke of Aquitaine; in the following August Henry was crowned for the second time King of England. Only the youngest child, scarcely five years old, was still "John Lackland," and in this same year Henry provided a dominion for John by a treaty of marriage between him and the heiress of the Count of Maurienne. Her inheritance stretched from the Lake of Geneva almost to the Gulf of Genoa; and the marriage would carry the Angevin dominions almost from the Atlantic to the Alps, and give into Henry's control every pass into Italy from the Great St. Bernard to the Col di Tenda, and all the highways by which travellers from Geneva and German lands beyond it, from Burgundy or from Gaul, made their way to Rome. To celebrate such a treaty Henry forgot his thrift. The two kings of England travelled with ostentatious splendour to meet the Count of Maurienne in Auvergne in January 1173. The King of Aragon and the Count of Toulouse met them at Montferrand, and a peace which Henry concluded between Toulouse and Aragon declared the height of his influence. Raymond bent at last to do homage for Toulouse, an act of submission which brought the dominion of Anjou to the very border of the Mediterranean.
