The Duchy of Limburg or Limbourg was an imperial estate of the Holy Roman Empire. Much of the area of the duchy is today located within Liège Province of Belgium, with a small portion in the municipality of Voeren, an exclave of the neighbouring Limburg Province. Its chief town was Limbourg-sur-Vesdre, in today's Liège Province.
The Duchy of Jülich 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.
The coat of arms of Luxembourg has its origins in the Middle Ages and was derived from the arms of the Duchy of Limburg, in modern-day Belgium and the Netherlands. In heraldic language, the arms are described as: Barry of ten Argent and Azure, a Lion rampant queue forchée Gules crowned, armed and langued Or.
Burg Castle, located in Burg an der Wupper (Solingen), is the largest reconstructed castle in North Rhine-Westphalia, Germany and a popular tourist attraction. Its early history is closely connected to the rise of the Duchy of Berg.

Henry was also related to the counts of Arlon. Waleran I was probably his father-in-law rather than his father.
