Limbourg
Limbourg was an imperial duchy between the Meuse and Aachen, ruled from its cliff-top town on the Vesdre. After Brabant's victory at Worringen in 1288, it shared Brabant's ruler; in 1337 that ruler was John III.
The duchy passed to Valois Burgundy in 1404 and the Habsburgs in 1482, becoming one of the Seventeen Provinces. It subsequently came under Spanish and Austrian rule in the Southern Netherlands. French revolutionary forces dissolved the duchy in 1794, and its territory became part of the Ourthe department.
