But in the course of the next few years Innocent was obliged to take up a totally different attitude in this struggle in consequence of disappointments elsewhere. There were two such which fell especially heavily upon him during the first half of his reign. He inherited from his predecessor a quarrel with Philip Augustus of France. Philip lost his first wife in 1190; in 1193 his designs against England caused him to marry Ingebiorg, a sister of the King of Denmark. Immediately after the marriage he took a dislike to her, refused to live with her, and obtained from an assembly of his own clergy a sentence of divorce, founded on an allegation of some very distant relationship between him and his new wife. Ingebiorg and her brother appealed to Pope Celestine III, who declared the sentence of divorce illegal and null. Philip not only paid no attention to the numerous letters and legates of the Pope, but he tried to make the divorce irrevocable by taking a new wife. After several rebuffs he found in Agnes of Meran, the daughter of a Bavarian noble, one who was willing to accept the dubious position (1196). Innocent III at once took up an uncompromising attitude, and instructed his legates that if Philip refused to send away Agnes and to restore Ingebiorg, they should put the kingdom under an interdict preparatory to a sentence of personal excommunication against Philip and Agnes themselves. Those bishops who dared to publish the interdict were seriously maltreated by the King; but after nine months of resistance the distress of his people at the cessation of religious services caused him to submit; he pretended to take back Ingebiorg, and the interdict was raised (1200). But he did not send away Agnes, and a renewal of the interdict was only averted by Agnes' death in 1201. Innocent, desiring to be conciliatory, actually declared Agnes' two children legitimate. Philip still, however, pressed for a divorce from Ingebiorg, declaring that he was bewitched by her. After his victory over John of England in 1204 he became more than ever obdurate to papal remonstrances, and he even contemplated a new marriage. Innocent was not in a position to drive him to extremes, and was obliged to temporise for a time. Eventually, however, he reduced Philip to submission. [Sidenote: The Fourth Crusade.]
