Book excerpt: Britons and Anglo-Saxons offers an interdisciplinary approach to the history of the Lincoln region in the post-Roman period. It is argued that, by using all of the available evidence together, significant advances can be made in our understanding of what occurred. In particular, this approach indicates that a British polity named *Lindes was based at Lincoln into the sixth century, and that the seventh-century Anglo-Saxon kingdom of Lindsey (Old English Lindissi) had an intimate connection with this British political unit. The picture that emerges is arguably of importance not only from the perspective of the history of the Lincoln region but also nationally, helping to answer key questions regarding the origins of Anglo-Saxon kingdoms, the nature and extent of Anglian-British interaction in the core areas of Anglo-Saxon immigration, and the conquest and settlement of Northumbria. This second edition of Britons and Anglo-Saxons includes a new introduction discussing recent research into the late and post-Roman Lincoln region.
