The native Britons had converted to Christianity under Roman rule. The Anglo-Saxon invasions separated the British church from European Christianity for centuries, so the church in Rome had no presence or authority in Britain, and in fact, Rome knew so little about the British church that it was unaware of any schism in customs. However, Æthelberht would have known something about the Roman church from his Frankish wife, Bertha, who had brought a bishop, Liudhard, with her across the Channel, and for whom Æthelberht built a chapel, St Martin's.
