The recorded history of Luxembourg begins with the acquisition of Lucilinburhuc (today Luxembourg Castle) situated on the Bock rock by Siegfried, Count of Ardennes, in 963 through an exchange act with St. Maximin's Abbey, Trier. Around this fort, a town gradually developed, which became the centre of a state of great strategic value. In the 14th and early 15th centuries, three members of the House of Luxembourg reigned as Holy Roman Emperors. In 1437, the House of Luxembourg suffered a succession crisis, precipitated by the lack of a male heir to assume the throne, which led to the territories being sold by Duchess Elisabeth to Philip the Good of Burgundy.
In the following centuries, Luxembourg's fortress was steadily enlarged and strengthened by its successive occupants, the Bourbons, Habsburgs, Hohenzollerns and the French.
Under the Treaty of Rastatt (1714), following the War of the Spanish Succession, the surviving portions of the Spanish Netherlands were ceded to Austria.

The Austrian Netherlands (German: Österreichische Niederlande; Dutch: Oostenrijkse Nederlanden; Latin: Belgium Austriacum) was the Southern Netherlands between 1714 and 1797. The period began with the acquisition of the territory by the Habsburg Monarchy under the Treaty of Rastatt in 1714 and lasted until its annexation during the aftermath of the Battle of Sprimont in 1794 and the Peace of Basel in 1795. Austria, however, did not relinquish its claim over the province until 1797 in the Treaty of Campo Formio. The Austrian Netherlands was a noncontiguous territory that consisted of what is now western Belgium as well as greater Luxembourg, bisected by the Prince-Bishopric of Liège. The dominant languages were German (including Luxembourgish), Dutch (Flemish), and French, along with Picard and Walloon.
