The military history of Luxembourg is central to the formation of Luxembourg as a nation from its formation around Luxembourg Castle in 963. A place of strategic military significance, Luxembourg had been fortified since the 10th century by over 50,000 m2 (538,195.52 sq ft) of walls and towers. Ruled by the House of Luxembourg in the early medieval period, Luxembourg was subsequently invaded by the Bourbons, Habsburgs, Hohenzollerns, and the French, among others.
