Still holding the supreme power, the Church alone could bring the peace for which the country longed. At Romont, near the borders of Gruyere, Hughes, Bishop of Lausanne, invoking a great assembly of prelates, proclaimed the _Treve de Dieu_ before a throng of people carrying palm branches and crying "_Pax, Pax Domini_." Thus in this corner of the world was adopted the law originating in Acquitaine, which prevailed over all Europe and which alone controlled in those strange times the violence and the pillage which was the permitted privilege of the robber bishops and the robber lords. Gruyere and its rulers reflected the influence of the all-powerful hierarchy, and Turimbert and his successors took their part in the great religious society extending over all Europe, where the conservation of faith was of supreme importance, and when men belonged more to the church than to their country. The possession of the great monasteries surpassed those of the largest landholders, and Rome with its mighty prelates for the second time became the capital of the world. When Hildebrand the monk, mounting the papal throne as Gregory VII, excommunicated the German Emperor, Henry IV, he placed the imperial crown upon the head of none other than Rudolph of Rheinfelden, the governor of Transjurane Burgundy and of the province of Gruyere. After Henry, forced to submission, had scaled the icy heights of the Alps to prostrate himself before Hildebrand at Canossa, after Rudolph had been killed in battle by Henry's supporter Godfrey de Bouillon, Hildebrand's pupil and successor Urban II, journeying to Clermont in Cisjurane Burgundy, summoned all Europe in torrents of fiery eloquence to rise and deliver the Holy Land from the power of the Saracens. Unmarked in the churchly parchments which alone record the history of these times, were the successors of Turimbert; but in the period of the first Crusade, Guillaume I, of the succeeding and unbroken line of Gruyere counts, appears as the head of a numerous and powerful family preeminent for their loyalty to the church. Among the shining names of chivalry immortalized in the annals of the Holy wars are those of Guillaume, of his son Ulric, chanoine of the Church at Lausanne, and of his nephews Hughes and Turin.
