NassauWeilburg

NassauWeilburg refers to a former principality of the Holy Roman Empire, and later a duchy within the German Confederation. Its territory was situated in the present-day German state of Hesse. The ruling House of Nassau-Weilburg was a cadet branch of the House of Nassau.

The origins of Nassau-Weilburg can be traced back to the division of the House of Nassau. In the 14th century, the line split, with one branch establishing Nassau-Weilburg. The principality grew and consolidated its territory over several centuries, often through inheritance and strategic alliances. Its capital was the town of Weilburg, located on the Lahn River.

Nassau-Weilburg played a role in various European conflicts and political developments of its time. During the Napoleonic era, it was mediatized and subsequently became part of the newly formed German Confederation in 1815 as a duchy. The duchy maintained its independence until 1866 when it was annexed by the Kingdom of Prussia following the Austro-Prussian War. The last Duke of Nassau-Weilburg was Adolf, who later became the Grand Duke of Luxembourg. The legacy of Nassau-Weilburg is primarily visible in the historical architecture of Weilburg and its surrounding regions.
