Ceawlin ([ˈtʃæɑw.lin] CHOW-lin; also spelled Ceaulin, Caelin, Celin, died ca. 593) was a King of Wessex. He may have been the son of Cynric of Wessex and the grandson of Cerdic of Wessex, whom the Anglo-Saxon Chronicle represents as the leader of the first group of Saxons to come to the land which later became Wessex. Ceawlin was active during the last years of the Anglo-Saxon expansion, with little of southern England remaining in the control of the native Britons by the time of his death.
The chronology of Ceawlin's life is highly uncertain. The historical accuracy and dating of many of the events in the later Anglo-Saxon Chronicle have been called into question, and his reign is variously listed as lasting seven, seventeen, or thirty-two years. The Chronicle records several battles of Ceawlin's between the years 556 and 592, including the first record of a battle between different groups of Anglo-Saxons, and indicates that under Ceawlin Wessex acquired significant territory, some of which was later to be lost to other Anglo-Saxon kingdoms. Ceawlin is also named as one of the eight "bretwaldas", a title given in the Chronicle to eight rulers who had overlordship over southern Britain, although the extent of Ceawlin's control is not known.
