to Pope Gregory IV gained them papal support for the overthrow of Emperor Louis. Upon Louis the Pious' return to power in 834, he deposed Saint Agobard from his see, to the consternation of Rome. There were unsubstantiated rumors in this period that Louis' second wife Judith was a converted Jew, as she would not accept the ordinatio for their first child. Jews were engaged in export trade, particularly traveling to Palestine under Charlemagne. When the Normans disembarked on the coast of Narbonnese Gaul, they were taken for Jewish merchants. One authority said the Jewish traders boasted about buying whatever they pleased from bishops and abbots. Isaac the Jew, who was sent by Charlemagne in 797 with two ambassadors to Harun al-Rashid, the fifth Abbasid Caliph, was probably one of these merchants. He was said to have asked the Baghdad caliph for a rabbi to instruct the Jews whom he had allowed to settle at Narbonne (see History of the Jews in Babylonia). Capetians Persecutions (987–1137) There were widespread persecutions of Jews in France beginning in 1007 or 1009.

Robert the Pious is well known for his lack of religious tolerance and for the hatred which he bore toward heretics; it was Robert who reinstated the Roman imperial custom of burning heretics at the stake.

A notable of the town, Jacob b. Jekuthiel, a Talmudic scholar, sought to intercede with Pope John XVIII to stop the persecution in Lorraine (1007). Jacob undertook the journey to Rome, but was imprisoned with his wife and four sons by Duke Richard, and escaped death only by allegedly miraculous means. He left his eldest son, Judah, as a hostage with Richard while he and his wife and three
