There were archbishops in London, York and Caerleon and bishops in Lincoln before the 4th century. The following is a simplified breakdown of the creation of dioceses since St Augustine's 6th/7th century dioceses. It is simplified in that not every new diocese is formed from only one predecessor – they have often taken territory from two or more neighbouring dioceses. Today's dioceses are highlighted in
bold type. •
