Edward, Duke of Guelders (12 March 1336 – 24 August 1371), Duke of Guelders and Count of Zutphen (1361–1371) was the youngest son of Rainald II of Guelders and his second wife, Eleanor of Woodstock, daughter of Edward II of England.
In 1350, with encouragement from his mother, Edward began a devastating civil war against his brother Rainald III for control of the Duchy of Guelders. Edward led the Bronkhorster (civil) faction which in 1361 in a battle at Tiel defeated the Heekeren (aristocratic) faction, led by Edward's incapable brother who was captured and imprisoned. Edward governed well and powerfully, despite the conditions against him. He allied himself with the Bishops of Lüttich and with Jülich and Kleve. In 1371, his brother-in-law and supporter, William II, Duke of Jülich, got into a dispute with Wenceslaus I, Duke of Luxembourg. The dispute culminated in the Battle of Baesweiler in which William defeated Wenceslaus, but Edward was mortally wounded in the battle and died on 24 August 1371. He is buried in the Kloster Graefenthal. Upon Edward's death, his brother Rainald regained the Duchy of Guelders but Rainald died shortly afterwards, on 4 December 1371. As neither Edward nor Rainald had children, another war of succession for Guelders began, with the Bronkhorster faction supporting Edward and Rainald's half-sister Maria, wife of William II of Jülich and the Heerkeren faction supporting their half-sister Mathilde, wife of John II, Count of Blois. In 1377, Emperor Charles IV awarded the Duchy of Guelders and the County of Zutphen to Maria's son William of Jülich. After her total defeat in the Battle of Hönnepel on 24 March 1379, Mathilde renounced her claim to Guelders and Zutphen.

Edward Duke (1779–1852), was an English antiquary.
Born in Hungerford on 24 September 1779, he was the second son of Edward Duke of Lake House, Wiltshire, by Fanny, daughter of John Field of Islington. He was educated at Magdalen Hall, Oxford, where he graduated B.A. 1803, M.A. 1807. He was ordained in 1802, and engaged in clerical work at Turkdean, Gloucestershire, and Salisbury. In 1805 he came into the estates and the mansion at Lake, which had been in his family since 1578.
Duke devoted his leisure to antiquities. In company with Sir R. C. Hoare he explored the tumuli on his estates, and the antiquities there discovered were described in Hoare's Ancient Wilts, and were preserved in the museum at Lake House. Between 1823 and 1828 Duke contributed to the Gentleman's Magazine, chiefly on Wiltshire antiquities. In his Druidical Temples of the County of Wilts (1846), he maintained that the early inhabitants of Wiltshire had "pourtrayed a vast planetarium or stationary orrery on the face of the Wiltshire downs", the earth being represented by Silbury Hill, and the sun and planets, revolving round it, by seven "temples", four of stone and three of earth, placed at their proper distances. A review in the Christian Remembrancer said "it has seldom been our unhappy fate to wade through a book, in the pages of which we could find less instruction of any kind, or a larger number of the most puerile absurdities".
The first count of Guelders was Gerard IV, Lord of Wassenberg.
During Reinoud II's reign, the county of Guelders was elevated to a duchy.
After the death of Reginald III without issue, two of his sisters disputed the succession of the Duchy of Guelders:
