Augustine of Canterbury (c. first third of the 6th century – 26 May 604) was a Benedictine monk who became the first Archbishop of Canterbury in the year 598. He is considered the "Apostle to the English" and a founder of the English Church.
Augustine was the prior of a monastery in Rome when Pope Gregory the Great chose him in 595 to lead a mission, usually known as the Gregorian mission, to Britain to convert the pagan King Æthelberht of the Kingdom of Kent to Christianity. Kent was probably chosen because it was near the Christian kingdoms in Gaul and because Æthelberht had married a Christian princess, Bertha, daughter of Charibert I the King of Paris who was expected to exert some influence over her husband. Before reaching Kent the missionaries had considered turning back but Gregory urged them on and, in 597, Augustine landed on the Isle of Thanet and proceeded to Æthelberht's main town of Canterbury.
King Æthelberht converted to Christianity and allowed the missionaries to preach freely, giving them land to found a monastery outside the city walls. Augustine was consecrated bishop of the English and converted many of the king's subjects, including thousands during a mass baptism on Christmas Day in 597. Pope Gregory sent more missionaries in 601, along with encouraging letters and gifts for the churches, although attempts to persuade the native Celtic bishops to submit to Augustine's authority failed. Roman Catholic bishops were established at London and Rochester in 604, and a school was founded to train Anglo-Saxon priests and missionaries. Augustine also arranged the consecration of his successor, Laurence of Canterbury. Augustine died in 604 and was soon revered as a saint.
