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.
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 was betrothed in 1368 to Katherine of Bavaria (30 May 1361 – 10 November 1400, buried Kloster Monkhuizen), daughter of Albert I, Duke of Bavaria and Margaret of Brieg.
