Adolf , Herzog von Jülich-Berg
d.14 Jul 1437 Cologne, Cologne, Nordrhein-Westfalen, Germany
Facts and Events
Adolf, Duke of Jülich-Berg (c. 1370 – 14 July 1437), was the first Duke of the combined duchies of Jülich and Berg. He was the son of William VII of Jülich, 1st Duke of Berg and Anna of the Palatinate.
In 1397, Adolf rebelled against his father along with his brother William, ravaged Düsseldorf and imprisoned his father. He was outlawed and was subsequently subdued in 1405. Upon his father's death in 1408, Adolf became the 2nd Duke of Berg. Adolf fought against Lorraine and other pretenders for Bar but surrendered after his capture in 1417. His father's cousin, Reginald, Duke of Jülich and Guelders, had no heirs and upon his death in 1423, Adolf succeeded him as Duke of Jülich, thus becoming the first duke of the combined duchies of Jülich and Berg. Adolf also began a year-long hereditary war against the House of Egmond for the dukedom of Guelders but could not win even with financial support from Sigismund, Holy Roman Emperor, who supported Adolf in this fight despite Adolf's opposition to Sigismund's coronation at Aachen in 1414. Adolf supported the Roman candidate in the Council of Constance which ended the Western Schism. He traditionally fought against the Archibishop of Cologne. He later secured Monschau-Montjoie and in 1428 he seized Lievandal-Wevelinghoven.
Adolf had only one son who died before him so after Adolf's death in 1437, the dukedom of Jülich-Berg passed to his nephew Gerhard, son of his brother William. Adolf died in Cologne on 14 July 1437 and is buried at St. Martin's Church in Cologne.
