Arnold, Duke of Guelders

Arnold of Egmond (14 July 1410, Egmond-Binnen, North Holland – 23 February 1473, Grave) was Duke of Guelders, Count of Zutphen. He was son of John II of Egmond and Maria van Arkel.

On 11 July 1423, Arnold of Egmond, who was still a boy in years, succeeded Duke Reinald IV. Arnold was the grandson of Reinald's sister, Johanna. Although the Emperor Sigismund had invested the Duke of Berg with the duchy of Gelders, Arnold retained the confidence of the Estates by enlarging their privileges, and enjoyed the support of Duke Philip of Burgundy. Arnold was betrothed, and afterwards united in marriage to Catherine of Cleves née Valois, a niece of Philip of Burgundy. Subsequently, however, Duke Arnold fell out with his ally as to the succession to the see of Utrecht, whereupon Philip joined with the four chief towns of Guelders in the successful attempt of Arnold's son Adolf to substitute his own for his father's authority. When Charles the Bold became Duke of Burgundy in 1467, after rejecting a compromise, Adolph was thrown into prison. Arnold, against the will of the towns and the law of the land, pledged his duchy to Charles for 300,000 Rhenish florins (1471). Upon Arnold's death two years later, Charles took possession of the duchy, starting a serie of wars that would last more than 70 years.
