After Cenwealh's death in 673, his widow, Seaxburh, held the throne for a year; she was followed by Æscwine, who was apparently descended from another brother of Ceawlin. This was one of several occasions on which the kingship of Wessex is said to have passed to a remote branch of the royal family with an unbroken male line of descent from Cerdic; these claims may be genuine, or may reflect the spurious assertion of descent from Cerdic to legitimise a new dynasty. Æscwine's reign only lasted two years, and in 676 the throne passed back to the immediate family of Cenwealh with the accession of his brother Centwine. Centwine is known to have fought and won battles against the Britons, but the details have not survived.
