Britons and Anglo-Saxons offers an interdisciplinary approach to the history of the Lincoln region in the post-Roman period, drawing together a wide range of sources. In particular, it indicates that a British polity named *Lindēs was based at Lincoln into the sixth century, and that the seventh-century Anglo-Saxon kingdom of Lindsey (Lindissi) had an intimate connection to this British political unit. The picture that emerges is also of importance nationally, helping to answer key questions regarding the nature and extent of Anglian-British interaction and the origins of Anglo-Saxon kingdoms.
