 Prior to their conquest by England, most churches have records of bishops and priests but not an established parish system.Pre-conquest, most Christians would not attend regular services but relied on members of the monastic communities who would occasionally make preaching tours through the area.At the end of the 6th century, Pope Gregory I dispatched a mission under Augustine of Canterbury to convert the Anglo-Saxons, establish new sees and churches throughout their territories, and reassert papal authority over the native church.
