Research Notes:

King of Kent from 24 Feb 616 to 20 Jan 640.

Eadbald's accession was a significant setback for the growth of the church, since he retained his indigenous paganism and did not convert to Christianity for at least a year, and perhaps for as much as eight years. He was ultimately converted by either Laurentius or Justus, and separated from his first wife, who had been his stepmother, at the insistence of the church. Eadbald's second wife was Emma, who may have been a Frankish princess....

Eadbald's influence was less than his father's, but Kent was powerful enough to be omitted from the list of kingdoms dominated by Edwin of Northumbria. Edwin's marriage to Eadbald's sister, Æthelburg, established a good relationship between Kent and Northumbria which appears to have continued into Oswald's reign. When Æthelburg fled to Kent on Edwin's death in about 633, she sent her children to Francia for safety, fearing the intrigues of both Eadbald and Oswald. The Kentish royal line made several strong diplomatic marriages over the succeeding years, including the marriage of Eanflæd, Eadbald's niece, to Oswiu, and of Eorcenberht to Seaxburh, daughter of King Anna of East Anglia.
