 Before the 20th century, the early medieval-founded London archdeaconry included parts of the East End as well as the City of London.The extent of the archdeaconry was reduced in 1912 (with the creation of the Archdeaconry of Hampstead) and in 1951 (with the creation of the Archdeaconry of Hackney) then latest border changes limited the archdeaconry to the limits of the City of London.This archdeaconry, comprising the City of Westminster, was created shortly before Klyberg's appointment in 1989.
