The uncertainty of this conflicting legislation, at times enforced, and at times dispensed with by the supreme power, led to innumerable complications and endless perplexity in private life. Indeed, a large portion of the canons are founded on responses given by the popes to settle cases of peculiar difficulty arising from ignorance or neglect of the discipline enjoined, and many of these reveal extreme hardship inflicted on those who could be convicted of no intentional guilt. Perhaps the most noteworthy instance of the troubles caused by the new regulations was that of Bossaert d’Avesnes, which resulted in a desperate war to determine the possession of the rich provinces of Flanders and Hainault. As it illustrates the doubts which still environed these particular points, and the conflicting decisions to which they were liable, even from the infallibility of successive popes, it may be worth briefly sketching here. When Baldwin of Flanders, Emperor of Constantinople, died in 1206, his eldest daughter Jane succeeded to his territories of Flanders and Hainault, while his second child, Margaret, was placed under the guardianship of Bossaert d’Avesnes. Bossaert was a relative of her mother, Mary of Champagne, and though he held the comparatively insignificant position of chantre of Tournay, he was yet a man of great repute and influence. With the assent and approbation of the estates of Flanders, Margaret and Bossaert were married, the issue of the union being three sons. Whether the fact of his having received the subdiaconate was publicly known or not is somewhat doubtful; but he seems at length to have been awakened to a sense of his uncertain position, when he went to Rome for the purpose of obtaining a dispensation and legitimating his children. Innocent III. not only refused the application, but commanded him to restore Margaret to her relatives and to do penance by a pilgrimage to the Holy Land. Disregarding these injunctions, he lived openly with his wife after his return and was excommunicated in consequence. At length Margaret left him and married Guillaume de Dampierre, while Bossaert was assassinated during a second visit to Rome, where he was seeking reconciliation to the church. When at last, in 1244, the Countess Jane closed her long and weary career by assuming the veil at Marquette, without leaving heirs, the children of Margaret by both marriages claimed the succession, and Margaret favored the younger, asserting, without scruple, that her elder sons were illegitimate. The difficult question was referred to St. Louis for arbitration, and in 1247 the good king assigned Flanders to Gui de Dampierre and Hainault to Jean d’Avesnes, thus recognizing both marriages as legitimate. This, of course, satisfied neither party. Innocent IV. was appealed to, and in 1248 he sent commissioners to investigate the knotty affair. They reported that the marriage of Bossaert had been contracted in the face of all
