The Anglo-Saxons believed that Wessex was founded by Cerdic and Cynric, but this may be a legend. The two main sources for the history of Wessex are the "Anglo-Saxon Chronicle" and the "West Saxon Genealogical Regnal List", which sometimes conflict. Wessex became a Christian kingdom after Cenwalh was baptised and was expanded under his rule. Cædwalla later conquered Sussex, Kent and the Isle of Wight. His successor, Ine, issued one of the oldest surviving English law codes and established a second West Saxon bishopric. The throne subsequently passed to a series of kings with unknown genealogies.
