Swæfred (or Suebred) was joint king of Essex along with his brother, Sigeheard, from 694 to 709, succeeding their father Sæbbi.
In 705, they became estranged from King Ine of Wessex for sheltering his rivals to the throne.
He issued a further charter related to land in the Dengie peninsula.
[3] This charter has been described as possibly spurious, although more recent writers have concluded that there is no reason to doubt its authenticity.
[4] By 709, Offa, son of their father's co-king and later rival, Sighere, was at least heir apparent and perhaps joint ruler of Essex when he traveled with King Cenred of Mercia to Rome.
