Reginald III, Duke of Guelders

Reginald III of Guelders (French: Rainaud or Renaud, known as "The Fat") (May 13, 1333 – December 4, 1371) was Duke of Guelders and Count of Zutphen from 1343 to 1361, and again in 1371. He was the son of Reginald II of Guelders and of Eleanor of Woodstock, daughter of Edward II of England.

With the death of his father in 1343, his mother held the regency until 1344. From 1350, his brother Edward asserted his rights and a quarrel of succession burst out between the two brothers until 1361. Reginald was overcome in Tiel and was imprisoned in the castle of Nijenbeek. There he became so large that he could not have left, even if the door had remained open—hence his appellation "The Fat"—. Edward died August 24, 1371, having been mortally wounded in the Battle of Baesweiler, and Reginald was released (according to the legend, the walls had to be cut away so he could leave); he held the ducal throne for only a short period, dying a few months later. He was buried at Graefenthal Abbey.

As he did not have a legitimate child, the succession passed to his sisters: Mathilde (also, Machteld), who was married to John II, Count of Blois, and Maria, wife of William II of Jülich and mother to William I of Guelders and Jülich, on whose behalf she claimed the throne of Guelders. The sisters and their respective followers (the Heeckerens, from the party led by families of Van Heeckeren and their relatives, the Van Rechterens, supported Mathilde, while the faction known as the Bronkhorsters followed Maria) fought for the duchy of Guelders in the Guelders War of Succession (sometimes known as The War of the Gueldric Succession, or, most commonly among historians, as the War of the Succession of Guelders.

Marriage and child

He married, in Tervuren on July 1, 1347, Marie of Brabant (1325–1399), lady of Turnhout, daughter of John III, Duke of Brabant and Marie d'Evreux.

They did not have children, but Reginald had an illegitimate daughter, Ponte of Guelders, who married Johan van Groesbeek (d. 1428), lord of Heumen and Malden.
