 Roman General Aetius then chose to negotiate for peace and concluded a treaty ("fœdus") with Clodion that gave the Franks the status of «foederati» fighting for Rome.The town's people were converted to Christianity in the late 4th century by Saint Innocent, who was killed in 410 during a barbarian attack on the town.In 499, after the conversion of Clovis I to Catholicism, a diocese ("évêché" in French) was created in Arras, the Roman Catholic Diocese of Arras, and given to Saint Vaast (also known as "Saint Vedast" in English), who remains the diocesan patron saint.
