It appears that Cynegils became king on the death of King
Ceolwulf . His relationship with Ceolwulf is uncertain. Cynegils is variously described in West Saxon sources as being a son of Ceolwulf, a son of
Ceol brother of Ceolwulf, a son of Ceola son of Cutha, a son of Cuthwine son of Ceawlin, and a son of Cuthwulf son of Cuthwine. Several of the sources give Cynegils a brother named Ceolwald, described as the grandfather of King
Ine. Although the
Anglo-Saxon Chronicle and Wessex king lists portray the West Saxons as ruled by a single king, the kingship was likely shared between two or more kings. The
Anglo-Saxon Chronicle for the year 611 states: "This year Cynegils succeeded to the government in Wessex, and held it one and thirty winters. Cynegils was the son of Ceol, Ceol of Cutha, Cutha of Cynric." Contradicting this simple account, the entry under 614 states that "This year Cynegils and Cwichelm fought at
Beandun, and slew two thousand and forty-six of the
Welsh." Likewise,
Bede writes that the attempted assassination of King
Edwin of Northumbria in 626 was ordered by
Cwichelm, king of the West Saxons. Whether the King Cwichelm of 614 is the same person as the king of the late 620s, and whether this person is the same as the Cwichelm who was
baptised, and died, , is disputed. Some historians presume Cwichelm to have been a son of Cynegils. In 628, Cynegils and Cwichelm fought King
Penda at
Cirencester.
The Anglo-Saxon Chronicle could be expected to report a victory, but does not, so Penda was likely the victor. Cynegils and Cwichelm appear to have been subject to
Edwin of Northumbria by this time, paying an enormous tribute of a hundred thousand
hides if Nick Higham's conception of the
Tribal Hidage's origins is correct. == Baptism ==
