The conversion to Christianity in Lindsey began by Paulinus. Bishop Wilfrid was appointed the bishop of Northumbria, which included Lindsey, in 665. After a delay, he was installed as bishop in 669. When he was expelled from Northumbria in 678, his diocese was divided up. Archbishop Theodore formed Lindsey into a separate diocese with its own bishop. According to the Anglo-Saxon Chronicle, in the year 678 Eadhed was the first bishop of Lindsey. In the 9th century, the Danes (Vikings) colonized Lindsey. This marked the end of the diocese of Lindsey.
