Augustine of Canterbury
Italian born, Augustine became a monk and prior of Rome's St. Andrew's Monastery.
When he was chosen by Pope Gregory the Great to lead forty monks in Anglo-Saxon evangelization, Augustine sailed in Kent in A.D. 597 and soon had baptized Ethelbert, king of Kent, and thousands of other new Christians. Since Britain had been home to Christianity for several centuries, this was not an entirely new venture. In fact, Ethelbert's French-born wife, Queen Bertha, was already Christian.
Five years later, Augustine built a school, cathedral, and the Monastery of St. Peter and St. Paul (later known as St. Augustine's) in Canterbury. He continued to build up the church despite tensions between him and the British Church, who ran things their own way and didn't appreciate the Roman Christians.
Augustine became the first Archbishop of Canterbury. He died sometime between 604 and 609, and was buried at St. Augustine's. Five centuries later, his remains were moved to the new (current) Canterbury Cathedral.
Augustine is considered a patron saint of England.
