Adolf IX of Berg (also referred to as Adolf VI) (c. 1280 – 3 April 1348) was the eldest son of Henry of Berg, Lord of Windeck and Agnes of the Mark.
Henry of Berg, Lord of Windeck was the son of Adolf VII of Berg and Margaret of Hochstaden. He was the younger brother of Adolf VIII of Berg and William I of Berg.
In 1308, Adolf succeeded as Count of Berg upon the death of his uncle William I of Berg who had no children. Adolf was an important and loyal supporter of Ludwig IV of Bavaria, helping him since 1314 in the war of succession. As a result of Adolf's 1312 marriage to Agnes of Cleves, he received the Rhine customs of Duisberg as a dowry and these were confirmed as an imperial fief by Emperor Louis in 1314. He continued the constant feuds between the House of Berg and the Archbishops of Cologne. In 1327/28, he joined Louis on his trip to Rome where he was crowned as Emperor. Adolf received the privilege to mint silver which he did at Wipperfürth. In 1337 Adolf joined the English-German Alliance which caused the start of the Hundred Years' War.
William I of Berg was the son of Count Adolf VII of Berg and of Margaret of Hochstaden.
Louis IV, called the Bavarian, of the house of Wittelsbach, was King of the Romans from 1314, King of Italy from 1327, and Holy Roman Emperor from 1328.
Silver is a chemical element with symbol Ag and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form, as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.
In 1312 Adolf was married to Agnes of Cleves (c. 1295 – aft. 1361), daughter of Dietrich VII, Count of Cleves and Margaret of Habsburg-Kiburg. He died on 3 April 1348 without children and was succeeded by his only surviving niece, Margaret of Ravensberg by right of her mother, and her husband Gerhard VI of Jülich as Count and Countess of Berg.

The duchy amalgamated with the County of Berg beyond the Rhine in 1423, and from then on also became known as Jülich-Berg.
The Duchy of Cleves was a State of the Holy Roman Empire which emerged from the mediaeval Hettergau (de).

Its history is closely related to that of its southern neighbours: the Duchies of Jülich and Berg, as well as Guelders and the Westphalian county of Mark. The Duchy was archaically known as Cleveland in English.
