Bertha, daughter of the Frankish king Charibert, married King Æthelbert of Kent sometime before 597, on condition that she could continue to practise her Christian faith. She did not convert her pagan husband. Pope Gregory the Great, writing to her in 601, rebuked her for this, but it Seems likely that the relationship with the greater Merovingian rulers influenced Æthelbert's acceptance of Augustine's Christian mission in 597. She died before 616.
