We will now quote Otto of Freising once more. “Up to the present time,” he says, writing of the year 1152, “two families have been famous in the Roman Empire, about the parts where Gaul and Germany meet, the Henries of Waiblingen, and the Welfs of Altdorf.” The Welfs go back to by far the greater antiquity. They probably did not originally belong to the Bajovarian stock, for we read elsewhere that they had “large possessions in the parts where Alemannia meets the Pyrenæan Mountains,” as Otto usually designates the Alps west of the Brenner. This Altdorf is a village near Ravensburg in Wurtemberg, between Ulm and Friedrichshafen. We first meet with the name in history about the year 820, when the Emperor Lewis I., “the Pious,” married as his second wife Judith, “daughter of the most noble Count Welf.” Somewhere about the middle of the tenth century, a Rudolf of the race was Count of Bozen. His son Welf took part in the insurrection of the Dukes of Worms and Suabia against their step-father Conrad II., “the Salic,” and lost some of his territories in consequence, Bozen passing to Etiko, an illegitimate member of the same house. The family must have soon been restored to the imperial favour, for before 1050 Welf III. appears as Duke of Bavaria. At his death, without issue, in 1055, he was succeeded by the son of his sister, who had married Azzo II. of Este. This Welf IV. fought on the side of Henry IV., against the revolted Saxons at the Unstrut, but soon rebelled himself. He became for a time the husband of the “great Countess” Matilda of Tuscany. Through him and his son Henry, “the Black,” the line was maintained; and though during the period at which we have arrived the head of the family for several generations bore the name of Henry, it is usually spoken of as “the house of the Welfs,”[9] and the name is borne by some member of the family at most times. At the accession of Lothar II. the head of the house was Henry, surnamed “the Proud.” With him the new emperor at once made close alliance, giving him his daughter Gertrude in marriage. Henry’s sister Judith was already married to Frederick of Suabia, but he sided with his father-in-law, and a struggle began which lasted for ten years, and in which the Hohenstaufen brothers had not entirely the worst of it. Conrad was actually anointed at Monza as King of Italy; but in the end, through the intervention of St. Bernard, peace was made, and lasted during the few remaining months of Lothar’s life. At his death in 1137 Conrad was elected. His first act was to take the duchy of Bavaria from Henry, and bestow it on Leopold, the Marquis of Austria, his own half-brother, and whole brother to Bishop Otto, the historian. Henry died very soon, leaving a young son, afterwards known as Henry “the lion,” and a brother, Welf, who at once took up the quarrel on behalf of his nephew. He beat Leopold; but when, emboldened by this success, he proceeded to
