Paulinus (died 10 October 644) was a Roman missionary and the first Bishop of York.[a] A member of the Gregorian mission sent in 601 by Pope Gregory I to Christianize the Anglo-Saxons from their native Anglo-Saxon paganism, Paulinus arrived in England by 604 with the second missionary group. Little is known of Paulinus' activities in the following two decades.
After some years spent in Kent, perhaps in 625, Paulinus was consecrated a bishop. He accompanied Æthelburg of Kent, sister of King Eadbald of Kent, on her journey to Northumbria to marry King Edwin of Northumbria, and eventually succeeded in converting Edwin to Christianity. Paulinus also converted many of Edwin's subjects and built some churches. One of the women Paulinus baptised was a future saint, Hilda of Whitby. Following Edwin's death in 633, Paulinus and Æthelburg fled Northumbria, leaving behind a member of Paulinus' clergy, James the Deacon. Paulinus returned to Kent, where he became Bishop of Rochester. After his death in 644, Paulinus was venerated as a saint.
Paulinus was a monk from Rome sent to the Kingdom of Kent by Pope Gregory I in 601, along with Mellitus and others, as part of the second group of missionaries sent to convert the Anglo-Saxons to Christianity. He was probably an Italian by birth. The second group of missionaries arrived in Kent by 604, but little is known of Paulinus' further activities until he went to Northumbria.
