context_page_description: The House of Nassau is a diversified aristocratic dynasty in Europe. It is named after the lordship associated with Nassau Castle, located in present-day Nassau, Rhineland-Palatinate, Germany. The lords of Nassau were originally titled "Count of Nassau", then elevated to the princely class as "Princely Counts". Early on they divided into two main branches: the elder branch, that gave rise to the German Emperor Adolf, and the younger branch, that gave rise to the Princes of Orange and the monarchs of the Netherlands.
  At the end of the Holy Roman Empire and the Napoleonic Wars, the Walramian branch had inherited or acquired all the Nassau ancestral lands and proclaimed themselves, with the permission of the Congress of Vienna, the "Dukes of Nassau", forming the independent state of Nassau with its capital at Wiesbaden; this territory today mainly lies in the German Federal State of Hesse, and partially in the neighbouring State of Rhineland-Palatinate. The Duchy was annexed in 1866 after the Austrian-Prussian War as an ally of Austria by Prussia. It was subsequently incorporated into the newly created Prussian Province of Hesse-Nassau.
