The king retaliated by sending troops of cavalry to devastate Saxony, and declared at Quierzy he would exterminate his foes unless they accepted Christianity.
Shortly after this division of the kingdom Charles died at Quierzy on the 22nd of October 741, and was buried at St Denis.
In the meantime, John VIII., who was menaced by the Saracens, was continually urging him to come to Italy, and Charles, after having taken at Quierzy the necessary measures for safeguarding the government of his dominions in his absence, again crossed the Alps, but this expedition had been received with small enthusiasm by the nobles, and even by Boso, Charles's brother-in-law, who had been entrusted by him with the government of Lombardy, and they refused to come with their men to join the imperial army.
Through the energy and activity of Hincmar the theories of Gottschalk were condemned at Quierzy (8J3) and Valence (855), and the decisions of these two synods were confirmed at the synods of Langres and Savonnieres, near Toul (859).
In vain Charles the Bald affirmed his royal authority in the capitularies of Quierzy-sur-Oise (857), Reims (860), Pistes (864), Gondreville (872) and Quierzy-sur-Oise (877); each time in exchange for assent to the royal will and renewal of oaths he had to acquiesce in.
Feudalism claimed its new rights in the capitulary of Quierzy-surOise in 857; the rights of the monarchy began to dwindle in 877.
On the other hand, in a letter of Lupus, abbot of The False Capitularies are for civil legislation what the False Decretals are for ecclesiastical legislation: three books of Capitularies of the Frankish kings, more of which are spurious than authen Ferrieres, written in 858, and in the synodical letter of the council of Quierzy in 857 are to be found quotations which are certainly from these false decretals; and further, an undoubted allusion in the statutes given by Hincmar to his diocese on the 1st of November 852.
