As early as May 31, Arnulph of Denmark resigned his claims in his favour (_see_ Wegener, note on p. 169), later on he purchased the acquiescence of another rival, Baldwin of Mons, by giving him his daughter to wife. Even William of Ypres in the end acknowledged his right to the throne, and was content to end his days obscurely as simple Lord of Löo. His first act as prince was to bring about peace between the Isegrins and the free landholders of the seaboard, and by his reconciliation with Hacket, whom he again reinstated in the châtelaincy of Bruges, the legal right of the Karls under his jurisdiction to the title of freemen was publicly acknowledged. Henceforth, until the Revolution, they were the _Francq Hostes_ or _Francons_ of the Liberty of Bruges. At his coronation, Dierick had solemnly sworn to respect the lawful rights and liberties of all his subjects, and he loyally kept his word. Throughout his long reign of forty years he always showed himself a good friend to commerce, a staunch upholder of popular institutions, and a generous supporter of the down-trodden and the oppressed. To him, says a Flemish writer, the greater number of the communes of Flanders are indebted alike for their origin and their development. During his reign were inscribed in the charters of the Flemish cities the germs of those rights and liberties which are to-day guaranteed by the Belgian Constitution. Like all good and wise men of his day, Dierick was profoundly impressed with the truths of Christianity, and after the manner of his age, he on more than one occasion took up the sword of the Crusader. On his return from one of these expeditions, he brought back with him to Bruges a treasure which has had no little influence on the architectural, and artistic, and religious development of the city; a vial of dark, ruby-coloured fluid, which tradition said was some of the water in which Joseph of Arimathea had once washed the blood-stained body of Christ. The early history of this precious memorial of Our Lord's Passion is veiled in mystery, but from the day when Dierick of Alsace brought the famous relic to Bruges the thread of its story is unbroken. The circumstances which led to his possession of it are well known. It was the time of the second Crusade. Dierick, roused perhaps by the preaching of St. Bernard at Furnes, or possibly moved thereto by reason of his kinship with Baldwin, King of Jerusalem--they had married two sisters--resolved to serve under the banner of the Cross, and in the month of June 1147, along with the Emperor Conrad and Louis VII. of France, set out for Palestine; but the campaign was almost barren of results. What with the perfidy of the Greeks, and the pettiness and jealousy of the European leaders, it could hardly have been otherwise. The little that had been accomplished, however, was due to the courage and perseverance of Dierick, and by way of recompense King Baldwin bestowed on him the relic in question.
