After the Romans left in 407 AD, the Saxons, the Angles and the Jutes, who were Anglosaxon peoples, invaded Britain. They came from Germany and Denmark and they were farmers, hunters and fishermen. Their culture wasn’t a written one and they practiced polytheistic cults.

III Paragraph : 

In the following two centuries the arrival of Christianity was the most relevant event. 
Gradually Roman bishops and missionaries of Celtic (Irish and Scottish) and Anglo-Saxon origins devoted themselves to evangelization of pagan and Aryan populations.
During this period, the so called 迭oman Christianity� met the 鼎eltic-Irish Christianity� that was practiced by Irish abbots in monasteries.

IV Paragraph : 

The most influential  Irish abbot was San Colombano, because he built hundreds of monasteries or churches and because he diffused Christianity in the whole of Europe during his journeys.  Anglo-Saxon monks acquired the desire of “peregrinatio pro Christo”, that is the passion that led the missionaries in their effort from him.

In particular, in Britain, Anglo-Saxon peoples were evangelized from VI century thanks to Saint Augustine. He founded the diocese of Canterbury, that became the religion center of the new cult.
In 597 AD Pope Gregory sent a group of about 40 men led by monk Saint Augustine to Kent. King Aethelberht of Kent permitted the monks to preach in his kingdom and in time he was converted. Meanwhile in 627 King Edwin of Northumbria (the North of England) and all his nobles were baptized. The other Anglo-Saxon kingdoms adopted Christianity following the example of the first two:   in 630 a Christian called Sigeberht became King of East Anglia; Pope Honorious sent a man to convert the West Saxons; missionaries also preached in the kingdom of Mercia (the Midlands) and in 653 King Paeda of Mercia was converted and baptized too and gradually the realm was converted.
The last part of England to be converted to Christianity was Sussex. The conversion of the Saxons turned out to be the most difficult mission, but they finally adopted the new cult after Carlo Magno’s conquest in 804 AD.
In 664, during a council that took place in Whitby, the Celtic and Irish Church adapted to the Roman traditions.
