When did the Romans leave Britain?

According to one of well-known versions, the Britons expelled their Roman magistrates in 409 A.D., having lost the protection of the army (which was taken by Constantine III to Gaul in 407 A.D. to establish himself as Western Roman Emperor).

ON THE WHOLE, THE END OF ROMAN BRITAIN TOOK PLACE from 211 to 455 A.D..

However, the Catholic Church in England and Wales is still a part of the worldwide Catholic Church in full communion with the Pope!

Catholic Christianity was established in what are now England and Wales in the first century A.D.. In 597, the first authoritative papal mission, establishing a direct link from the Kingdom of Kent to Rome and to the Benedictine form of monasticism, was carried into effect by Augustine of Canterbury.

So, in a way, the 'Romans' have never been completely expelled from the territory of Great Britain! ( It's my own private opinion!) To my mind, this still is one of the reasons of conflicts between England and Ireland.
