Duchy of Jülich

The Duchy of Jülich (German: Herzogtum Jülich; Dutch: Hertogdom Gulik; French: Duché de Juliers) comprised a state within the Holy Roman Empire from the 11th to the 18th centuries. The duchy lay west of the Rhine river and was bordered by the Electorate of Cologne to the east and the Duchy of Limburg to the west. It had territories on both sides of the river Rur, around its capital Jülich – the former Roman Iuliacum – in the lower Rhineland. The duchy amalgamated with the County of Berg beyond the Rhine in 1423, and from then on also became known as Jülich-Berg. Later it became part of the United Duchies of Jülich-Cleves-Berg.

In the 9th century a certain Matfried was count of Jülich (pagus Juliacensis).[1] The first count in the gau of Jülich in Lower Lorraine, Gerhard I, was mentioned in 1003; his grandson Gerhard III began to call himself Count of Jülich in 1081. William IV, who became count in 1219, significantly enlarged the territory and in 1234 granted Jülich town privileges, provoking the Cologne Archbishop Konrad von Hochstaden, whose troops devastated the city five years later. William IV's son Walram (Count from 1278 to 1297) remained a fierce opponent of the Bishopric, supporting Duke John I of Brabant at the 1288 Battle of Worringen against Archbishop Siegfried II of Westerburg. Though Walram's younger brother Count Gerhard V had sided with German king Adolf of Nassau against his rival Albert I of Habsburg, he managed to retain his territories after Adolf of Nassau lost the Battle of Göllheim in 1298, and in 1314 supported the coronation of Louis IV of Wittelsbach at the nearby City of Aachen, once more against the will of the Cologne bishop. The long-time conflict came to an end when Gerhard's younger son Walram became Archbishop of Cologne in 1332. His elder brother Count William V in 1336 received the title of a margrave from Emperor Louis IV, and in 1356 Emperor Charles IV of Luxembourg raised William V to the rank of duke. His son Duke William II, however, became entangled in a fierce feud with the Emperor's half-brother Wenceslaus of Luxembourg, Duke of Brabant, whom he defeated at the Battle of Baesweiler in 1371.

Thereafter Jülich's history became closely intertwined with that of its neighbours: the Duchies of Cleves and Berg as well as Guelders and the County of Mark: Duke William II had married Mary, the daughter of Duke Reginald II of Guelders, and duchess herself after the death of her half-brother Reginald III of Guelders in 1371. William II settled the conflict with the Imperial House of Luxembourg and his son William III inherited both duchies. When in 1423 however his younger brother Rainald died without heirs, the Gelderland estates chose Arnold of Egmond as duke, while Jülich amalgamated with Berg and passed to Adolf, Duke of Jülich-Berg, who belonged to a younger branch, and who had obtained Berg by virtue of the marriage of one of his ancestors.[1]

In 1511 Duke John III of Cleves inherited Jülich and Berg through marriage with Maria of Jülich-Berg, the daughter of the last Duke, William IV. She inherited her father's estates: Jülich and Berg with the County of Ravensberg. From 1521 Jülich-Berg and Cleves formed the United Duchies of Jülich-Cleves-Berg[1] in a personal union under Duke John III.

When the last duke of Jülich-Cleves-Berg died without direct heirs in 1609, the War of the Jülich Succession broke out. It ended with the 1614 Treaty of Xanten, which divided the separate duchies between Palatinate-Neuburg and the Margraviate of Brandenburg. Jülich and Berg fell to Count Palatine Wolfgang William of Neuburg and after the last duke of Palatinate-Neuburg (also Elector of the Palatinate from 1685) Charles III Philip had died without issue in 1742, Count Charles Theodore of Palatinate-Sulzbach (after 1777 also Duke of Bavaria) inherited Jülich and Berg.

In 1794 Revolutionary France occupied the Duchy of Jülich (Duché de Juliers), which became part of the French département of the Roer. The Treaty of Lunéville in 1801 officially acknowledged the cession of Jülich to France. In 1815, following the defeat of Napoleon, the duchy became part of the Prussian[1] Province of Jülich-Cleves-Berg (after 1822 part of the Prussian Rhine Province), except for the cities Sittard and Tegelen, which became part of the United Kingdom of the Netherlands.
