A region and Anglo-Saxon kingdom of eastern England. Settled by Angles in the late fifth century AD, it was a powerful kingdom by the late sixth century but became a dependency of Mercia for long periods after 650. The Danes controlled the region from 886 to 917, after which it became an English earldom.
