Its name has been said to mean "island of eels", a reference to the creatures that were often caught in the local rivers for food. This etymology was first recorded by the Venerable Bede.[1]
History
Until the 17th century, the area was an island surrounded by a large area of fenland, a type of swamp. It was coveted as an area easy to defend, and was controlled in the very early medieval period by the Gyrwas, an Anglo-Saxon tribe. Upon their marriage in 652, Tondbert, a prince of the Gyrwas, presented Æthelthryth (who became St. Æthelthryth), the daughter of King Anna of the East Angles, with the Isle of Ely. She afterwards founded a monastery at Ely, which was destroyed by Viking raiders in 870, but was rebuilt and became a famous Abbey and Shrine.
In 1216, during the First Barons' War, the Isle was unsuccessfully defended against the army of King John.
Ely took part in the Peasants' Revolt of 1381.
During the English Civil War the Isle of Ely was held for the parliamentarians. Troops from the garrison at Wisbech Castle were used in the siege of Crowland and parts of the Fens were flooded to prevent Royalist forces entering Norfolk from Lincolnshire. The Horseshoe sluice on the river at Wisbech and the nearby castle and town defences were upgraded and cannon brought from Ely.[5]
The Fens were drained beginning in 1626 using a network of canals designed by Dutch experts.[6] Many Fenlanders were opposed to the draining as it deprived some of them of their traditional livelihood. Acts of vandalism on dykes, ditches, and sluices were common, but the draining was complete by the end of the century.[7]
Administration
From 1109 until 1837, the Isle was under the jurisdiction of the Bishop of Ely who appointed a Chief Justice of Ely and exercised temporal powers within the Liberty of Ely. This temporal jurisdiction originated in a charter granted by King Edgar in 970, and confirmed by Edward the Confessor and Henry I to the abbot of Ely. The latter monarch established Ely as the seat of a bishop in 1109, creating the Isle of Ely a county palatine under the bishop. An act of parliament in 1535/6 ended the palatine status of the Isle, with all justices of the peace to be appointed by letters patent issued under the great seal and warrants to be issued in the king's name. However, the bishop retained exclusive jurisdiction in civil and criminal matters, and was custos rotulorum. A chief bailiff was appointed for life by the bishop, and performed the functions of high sheriff within the liberty, who also headed the government of the city of Ely.[8]
An Act to explain and amend an Act of the Sixth and Seventh Years of His late Majesty, for extinguishing the Secular Jurisdiction of the Archbishop of York and the Bishop of Ely in certain Liberties in the Counties of York, Nottingham, and Cambridge.
The Liberty of Ely Act 1837 (7 Will. 4 & 1 Vict. c. 53) ended the bishop's secular powers in the Isle. The area was declared a division of Cambridgeshire, with the right to appoint justices revested in the crown. Following the 1837 Act the Isle maintained separate Quarter Sessions, and formed its own constabulary.
The title Marquess of the Isle of Ely was created in the Peerage of Great Britain for Prince Frederick. The title of Duke of Edinburgh was first created on 26 July 1726 by King George I, who bestowed it on his grandson Prince Frederick, who became Prince of Wales the following year. The subsidiary titles of the dukedom were Baron of Snowdon, in the County of Caernarvon; Viscount of Launceston, in the County of Cornwall; Earl of Eltham, in the County of Kent;[11] and Marquess of the Isle of Ely. The marquessate was apparently erroneously gazetted as Marquess of the Isle of Wight[11] although Marquess of the Isle of Ely was the intended title. In later editions of the London Gazette the Duke is referred to as the Marquess of the Isle of Ely.[12][13] Upon Frederick's death, the titles were inherited by his son Prince George. When he became George III in 1760, the titles "merged into the Crown", and ceased to exist.
Mining
Coprolites were mined in the area in the 1800s for their rich phosphate content.[14][15]
