Arnulf of Chocques (died 1118) was a leading member of the clergy during the First Crusade, being made Latin Patriarch of Jerusalem in 1099 and again from 1112 to 1118.
Arnulf may have been trying to make up for the problems he caused disproving the authenticity of the Lance, and the True Cross became the most sacred relic of the Kingdom of Jerusalem.
He was accused of various crimes: sexual relations with a Muslim woman, simony, and most importantly condoning the bigamous marriage of King Baldwin I to Adelaide del Vasto while his first wife Arda of Armenia was still alive.
He was briefly deposed by a papal legate in 1115, but appealed to Pope Paschal II and was reinstated in 1116, provided that he annul Baldwin and Adelaide's marriage.
[1] Arnulf married his niece Emma, also called Emelota, to Eustace Garnier, the Latin seigneur of Caesarea and Sidon.
