Ecgberht of Kent
Ecgberht I (also spelled Egbert) (died 4 July 673) was a King of Kent (664-673), succeeding his father Eorcenberht.He may have still been a child when he became king following his father's death on 14 July 664, because his mother Seaxburh was recorded as having been regent.

Ecgberht's court seems to have had many diplomatic and ecclesiastic contacts. He hosted Wilfrid and Benedict Biscop, and provided escorts to Archbishop Theodore and Abbot Adrian of Canterbury for their travels in Gaul.

The various versions of the Kentish Royal Legend state that, spurred on by his adviser Thunor, he had his cousins Æthelred and Æthelberht (sons of his uncle Eormenred) killed and had to pay wergild to their sister Domne Eafe, enabling her to build a Monastery at Thanet; this may reflect a dynastic struggle that ended in the success of Eorcenberht's line. The two murdered princes were later venerated as saints at Ramsey Abbey.A charter records Ecgberht's patronage of the monastery at Chertsey.

Ecgberht was succeeded by his brother Hlothhere, who was in turn succeeded by Ecgberht's sons, Eadric and still later Wihtred.
