continued his fruitful activity. Under Tharin's successor, Bishop Lepappe de Trevern, he withdrew more from public life. His last years were spent in retirement in the mother-house of the Sisters of Charity. Liebermann's name will live in theological literature through his well-known "Institutiones theologicæ", first published in five volumes (Mainz, 1819-27; 6th ed., 1844) and later in two (10th ed., Mainz, 1870). Owing to the correctness of its contents and its clear and well-ordered style, this work was used as a textbook for years in many theological seminaries in Germany, France, Belgium, and America. During the time of the Revolution, Liehermann published several anonymous pamphlets in defence of the rights of the Church and against the required oath of the civil constitution of the clergy. Of his sermons several have been published separately, e.g. "Lob- und Trauerrede bei Gelegenheit des Hintrittes des hochwürdigsten Herrn Joseph Ludwig Colmar, Bischof zu Mainz" (Mainz, 1818). After his death appeared:- "Liebermann's Predigten, herausgegeben von Freunden und Verehrern des Verewigten" (3 vols., Mainz, 1851-3). From 1825 to 1826 he was editor of the "Katholik".

Liège, Diocese op (Leodiensis). — Liège (Vicus Leudicus; Leodium; Legia) is now the capital of a Belgian province of the same name.
The first capital of this diocese was Tongres, northeast of Liège; its territory originally belonged to the Diocese of Trier, then to Cologne; but after the first half of the fourth century Tongres received autonomous organization. The boundaries were those of the Civitas Tungrorum, and they remained unchanged until 1559. These boundaries were, on the north, the Diocese of Utrecht; east, that of Cologne; south, the Dioceses of Trier and Reims; west, that of Cambrai. Thus Tongres extended from France, in the neighbourhood of Chimay, to Stavelot, Aachen, Gladbach, and Venlo, and from the banks of the Semois as far as Eeckeren, near Antwerp, to the middle of the Isle of Tholen and beyond Moerdyck, so that it included both Latin and Germanic populations. In 1559, its 1636 parishes were grouped in eight archdeaconries, and twenty-eight councils, chrétientés, or deaneries.
Some trace the bishops of Tongres to the first century, but the first Bishop was St. Servais, installed in 344 or 345 assisted at the Council of Rimini (359-60), and died in 384 (?). The invasion of 406 shattered the diocese, and its restoration required a long time. The conversion of the Franks began under Falco (first half of the sixth century) and continued under Sts. Domitian, Monulphus, and Gondulphus (sixth and seventh centuries). St. Monulphus built over the tomb of St. Servais a sumptuous church, near which his successors often resided. During the whole of the seventh century the bishops had to struggle against paganism. St. Amandus (647-50) abandoned the episcopal chair in discouragement, and built monasteries. St. Remaculus (650-60) did the same. St. Theodard (660-69), died a martyr.
St. Lambert (669-705?) completed the conversion of the pagans; probably about 705 he was murdered at Vicus Leudicus, for his defence of church property against the avarice of the neighbouring lords, and he was popularly regarded as a martyr. His successor, St. Hubert, built, to enshrine his relics, a basilica which became the true nucleus of the city, and near which the residence of the bishops was fixed.
Those bishops, nevertheless, continued to use the style of Bishop of the Church of Tongres, or Bishop of Tongres and of Liège. Agilbert (768-84), and Gerbald (785-810) were both placed in the see by Charlemagne. Hartgar built the first episcopal palace. Bishop Franco, who defeated the Normans, is celebrated by the Irish poet Sedulius. Stephen (908-20), Richaire (920-45), Hugh (945-47), Farabert (947-58) and Rathier were promoted from the cloister. To Stephen, a writer and composer, the Church is indebted for the feast and the Office of the Blessed Trinity. Rathier absorbed all the learning of his time. Heraclius, who occupied the see in 959, built four new parish churches, a monastery, and two collegiate churches, he inaugurated in his diocese an era of great artistic activity.
The domain of the Church of Liège had been developed by the donations of sovereign princes and the acquisitions of its bishops. Notger (972-1008), by securing for his see the feudal authority of a countship became himself a sovereign prince. This status his successors retained until the French Revolution: and throughout that period of nearly eight centuries the Prince-Bishopric of Liège, with a temporal jurisdiction of less extent than its spiritual, succeeded in maintaining its autonomy, though theoretically attached to the Empire. This virtual independence it owed largely to the ability of its bishops, under whom the Principality of Liège, placed between France and Germany, on several occasions played an important part in international politics. Notger, the founder of this principality, was also the second founder of his episcopal city. He rebuilt the cathedral of St. Lambert and the episcopal palace, finished the collegiate church of St. Paul, begun by Heraclius, facilitated the erection of Sainte-Croix and Saint-Denis, two other collegiate churches, and erected that of St. John the Evangelist. This bishop also strengthened the parochial organization of the city. He was one of the first to spread the observance of All Souls' Day, which he authorized for his diocese. But the most notable characteristic of Notger's administration was the development which, following up the work of Heraclius, he gave to education: thanks to these two bishops and to Wazo, "Liège for more than a century occupied among the nations a position in regard to science which it has never recovered". "The schools of Liège were, in fact, at that time one of the brightest literary foci of the period". Balderic of Looz (1008-18), Walbodon (1018-21), Durandus (1021-25), Reginard (1025-38), Nitard (1038-42), the learned Wazo, and Theoduin (1048-75) valiantly sustained the heritage of Notger. The schools went on forming many brilliant scholars, and gave to the Catholic Church Popes Stephen IX and Nicholas II.
In the reign of Henry of Verdun (1075-91) a tribunal was instituted (tribunal de la paix) to take cognizance of infractions of the Peace of God. Otbert (1091-1119) increased the territory of the principality. He remained faithful to Henry IV, who died as his guest. The violent death of Henry of Namur (1119-21) won for him veneration as a martyr. Alexander of Juliers (1128-34) received at Liège the pope, the emperor, and St. Bernard. The episcopate of Raoul of Zachringen was marked by the preaching of the reformer, Lambert le Bègue, who is credited with founding the béguines. The time at length came when the schools of Liège were to yield to the University of Paris, and the diocese supplied that university with some of its first doctors - William of Saint-Thierry, Gerard of Liège, Godfrey of Fontaines.
Albert of Louvain was elected Bishop of Liège in 1191, but Emperor Henry VI, on the pretext that the election was doubtful, gave the see to Lothair of Hochstadt. Albert's election was confirmed by the pope, and he was consecrated, but was assassinated at Reims, in 1192, by three German knights. It is probable that the emperor was privy to this murder, the victim of which was canonized. In 1195 Albert de Cuyck (1195-1200) formally recognized the franchises
