Bertha of Kent was a 6th-century queen consort of King Æthelberht of Kent, known for her role in the early spread of Christianity in England. She was a Frankish princess, the daughter of Charibert I, and married Æthelberht around 580 AD. Her marriage helped establish political alliances between the Anglo-Saxons and the Franks. Bertha was a devout Christian and brought a chaplain, Lupus, with her to England. She influenced her husband to allow the practice of Christianity in his kingdom, which eventually led to the arrival of Saint Augustine of Canterbury in 597 AD, further promoting the faith in England.
