On arriving at Angers, Louis found the empress Hermengarde dying; and two days afterward she was dead. He had a tender heart which was not proof against sorrow; and he testified a desire to abdicate and turn monk. But he was dissuaded from his purpose; for it was easy to influence his resolutions. A little later, he was advised to marry again, and he yielded. Several princesses were introduced; and he chose Judith of Bavaria, daughter of Count Welf (Guelf), a family already powerful and in later times celebrated. Judith was young, beautiful, witty, ambitious, and skilled in the art of making the gift of pleasing subserve the passion for ruling. Louis, during his expedition into Brittany, had just witnessed the fatal result of a woman's empire over her husband; he was destined himself to offer a more striking and more long-lived example of it. In 823, he had, by his new empress Judith, a son, whom he called Charles, and who was hereafter to be known as Charles the Bald. This son became his mother's ruling, if not exclusive, passion, and the source of his father's woes. His birth could not fail to cause ill-temper and mistrust in Louis' three sons by Hermengarde, who were already kings. They had but a short time previously received the first proof of their father's weakness. In 822, Louis, repenting of his severity toward his nephew, Bernard of Italy, whose eyes he had caused to be put out as a punishment for rebellion, and who had died in consequence, considered himself bound to perform at Attigny, in the church and before the people, a solemn act of penance; which was creditable to his honesty and piety, but the details left upon the minds of the beholders an impression unfavorable to the Emperor's dignity and authority. In 829, during an assembly held at Worms, he, yielding to his wife's entreaties, and doubtless also to his own yearnings toward his youngest son, set at naught the solemn act whereby, in 817, he had shared his dominions among his three elder sons; and took away from two of them, in Burgundy and Alemannia, some of the territories he had assigned to them, and gave them to the boy Charles for his share. Lothair, Pépin, and Louis thereupon revolted. Court rivalries were added to family differences. The Emperor had summoned to his side a young southron, Bernard by name, duke of Septimania and son of Count William of Toulouse, who had gallantly fought the Saracens. He made him his chief chamberlain and his favorite counsellor. Bernard was bold, ambitious, vain, imperious, and restless. He removed his rivals from court, and put in their places his own creatures. He was accused not only of abusing the Emperor's favor, but even of carrying on a guilty intrigue with the empress Judith. There grew up against him, and, by consequence, against the Emperor, the Empress, and their youngest son, a powerful opposition, in which certain ecclesiastics, and, among them, Wala, abbot of Corbie, cousin-german and but lately one of the privy
