 Reforms within the Church of England led to the annexation of Dorset from the abolished diocese of Bristol in 1836; Berkshire, however, was removed the same year and given to Oxford.In 1925 and 1974, new suffragan bishops were appointed to assist the Bishop of Salisbury; the new offices were titled the bishops of Sherborne and Ramsbury, respectively.Until 2009 the bishops operated under an episcopal area scheme established in 1981, with each suffragan bishop having a formal geographical area of responsibility, and being known as "area bishops".
