This article describes the history of Suffolk, the English county. Historical setting Anglo-Saxon control The county of Suffolk (Sudfole, Suthfolc, meaning 'southern folk') was formed from the south part of the kingdom of East Anglia which had been settled by the Angles in the latter half of the 5th century. The most important Anglo-Saxon settlements appear to have been made at Sudbury and Ipswich. Before the end of the Norman dynasty, strongholds had arisen at Eye, Clare, Walton and Framlingham. Probably the establishment of Suffolk as a separate shire was scarcely completed before the Conquest, and although it was reckoned as distinct from Norfolk in the Domesday Survey of 1086, the fiscal administration of Norfolk and Suffolk remained under a single sheriff until 1575. The boundary of the county has undergone very little change, though its area has been considerably affected by coast erosion. Parts of Gorleston and Thetford, which formerly belonged to the ancient county of Suffolk, are now within the administrative county of Norfolk, and other slight alterations of the administrative boundary have been made. Under the Local Government Act of 1888 Suffolk was divided into the two administrative counties of East and West Suffolk. Land division At first the whole shire lay within the diocese of Dunwich which was founded approximately 631. In 673 a new bishopric was established at Elmham to comprise the whole of Norfolk which had formerly been included in the see of Dunwich. The latter came to an end with the incursion of the Danes, and on the revival of Christianity in this district Suffolk was included in the diocese of Elmham, subsequently removed from South Elmham to Thetford and thence to Norwich. The archdeaconry of Sudbury was transferred by the ecclesiastical commissioners to the diocese of Ely. This archdeaconry had been separated from the original archdeaconry of Suffolk in 1127. In 1256 the latter included thirteen deaneries which have since been subdivided, so that-at present it contains eighteen deaneries; Sudbury archdeaconry which comprised eight deaneries in 1256 now (1911) includes eleven. There were also three districts under jurisdiction of Canterbury and one under that of Rochester. The shire court was held at Ipswich. In 1831 the whole county contained twenty-one hundreds and three municipal boroughs. Most of these hundreds were identical with those of the Domesday Survey, but in 1086 Babergh was rated as two hundreds, Cosford, Ipswich and Parham as half
