For the purposes of his book, "East End Past", Richard Tames regards the area as coextensive with the London Borough of Tower Hamlets: however, he acknowledges that this narrow definition excludes parts of southern Hackney, such as Shoreditch and Hoxton, which many would regard as belonging to the East End.
