Aicard Pope Urban II, the greatest of the Gregorian reformers after Gregory, travelled through Languedoc and Provence, visiting Montpellier, Nîmes, Saint-Gilles, Tarascon, Avignon, Aix, Cavaillon, and other cities, preaching the First Crusade at the Council of Clermont in 1095, he had to avoid Arles, where the deposed bishop was still in power. Between 1098 and 1099, however, Aicard probably relinquished his see to follow the Crusade. Ghibbelin appeared for the first time in Urban's papal bull releasing the citizens of Arles from the penalties incurred in 1080. Aicard was in the Holy Land from 1103 to 1105, where he joined Raymond
Gerard (archbishop of York) archdeacon of Rouen. He served in the royal chancery under successive kings of England, William I and William II. Gerard was appointed Lord Chancellor of England in 1085, and was present at William I's deathbed in 1087. He continued as Chancellor to William Rufus until 1092; what precipitated his loss of office is unclear. He retained the king's trust, for Rufus employed him in 1095 along with William Warelwast on a diplomatic mission to Pope Urban II regarding Archbishop Anselm receiving the pallium, the sign of an archbishop's authority. Rufus offered to recognise Urban as pope rather than the Antipope
