The concept of a suffragan bishop in the Church of England was legalised by the Suffragan Bishops Act 1534. The first bishops consecrated under that Act were Thomas Manning, Bishop of Ipswich and John Salisbury, Bishop of Thetford on 19 March 1536. The last Tudor suffragan bishop in post was John Sterne, Bishop of Colchester, who died in post in 1607/8. No more suffragans were appointed for more than 250 years, until the consecration of Henry Mackenzie as Bishop of Nottingham on 2 February 1870. At that point, the sees of suffragans were still limited to the 26 towns named in the 1534 Act; the Suffragans Nomination Act 1888 allowed the creation of new suffragan sees besides the 26 so named. The appointment of bishops suffragan became much more common thereafter.
