The name was resurrected after the
Congress of Vienna for the

History
The United Duchies of Jülich-Cleves-Berg was a combination of states of the
Holy Roman Empire
The Holy Roman Empire, also known as the Holy Roman Empire of the German Nation after 1512, was a polity in Central and Western Europe, usually headed by the Holy Roman Emperor. It developed in the Early Middle Ages, and lasted for a millennium ...
. The duchies of
Jülich and
Berg united in 1423. Nearly a century later, in 1521, these two duchies, along with the
county of Ravensberg, fell extinct, with only the last duke's daughter
Maria von Geldern left to inherit; under
Salic law, women could only hold property through a husband or guardian, so the territories passed to her husband—and distant relative—
John III, Duke of Cleves and Mark as a result of their strategic marriage in 1509. These united duchies controlled most of the present-day North Rhine-Westphalia that was not within the ecclesiastical territories of
Electoral Cologne and
Münster.
During the reign of Duke
William the Rich, the United Duchies challenged
Emperor Charles V for control of the
Duchy of Guelders. Controlling Guelders would allow for the disconnected lands of the duchies to be connected by land. To counter the Habsburg Emperor, William attempted to form several alliances. For example, his sister,
Anne of Cleves, married
King Henry VIII of England to create an alliance between England and Jülich-Cleves-Berg. Nonetheless, Charles V defeated William in the
Guelders War, and William was forced to accept the
Treaty of Venlo. William also spent a lot of his reign developing his lands by constructing fortresses and residencies.
William also set two major laws, the Privilegium Unionis and Priviligium Successionis. The Privilegium Unionis had declared that the Duchies of Jülich, Cleves, and Berg would remain united rather than divided during succession. The Priviligium Successionis declared that in the case of the extinction of the male line, the duchies would pass to a female line.
Only a century after John III's marriage, however, the male line of the
House of La Marck, which ruled the duchies, fell extinct, prompting the
War of the Jülich Succession over the right to inherit the united duchies. William's son —
Duke John William — died without issue in 1609. His inheritance was claimed by the heirs of his two eldest sisters. Whilst the dukes, inspired by the
humanism of
Desiderius Erasmus, had managed to bear a "'" between the confessional disputes ensuing from the
Protestant Reformation, the heirs of the last duke's two eldest sisters were on opposite sides of the divide. The situation was further complicated by acquisitive desires of
Emperor Rudolph II and the
Wettin dukes of Saxony—the former particularly worrying to
Henry IV of France and the

Anna of Cleves was married to
Philip Louis, Count Palatine of Neuburg. As a result, after the
War of the Jülich Succession (one of the precursors to the
Thirty Years' War) was
settled at Xanten, the Protestant territories (Cleves, Mark and Ravensburg) passed to
Brandenburg-Prussia with the Catholic lands (Jülich and Berg) being awarded to the
Palatinate-Neuburg. Years of being trampled by armies had destroyed much of the lands' wealth that had been so renowned under William the Rich.
