The Province of York, or less formally the Northern Province, is one of two ecclesiastical provinces making up the Church of England and consists of 12 dioceses which cover the northern third of England and the Isle of Man. York was elevated to an archbishopric in AD 735: Ecgbert was the first archbishop. At one time the archbishops of York also claimed metropolitan authority over Scotland but these claims were never realised and ceased when the Archdiocese of St Andrews was established.
