Cond�, arrived and formed an army of young aristocrats willing to fight the French Revolution and restore the Ancien R�gime. The Army of Cond� joined with an allied army of Prussian and Austrian soldiers led by Duke of Brunswick in an unsuccessful invasion of France in 1792. This drew down the wrath of the First French Republic on the archbishop-elector; in 1794, Coblenz was taken by the French Revolutionary army under Marceau (who was killed during the siege), and, after the signing of the Treaty of Lun�ville (1801) it was made the capital of the new French department of Rhin-et-Moselle. In 1814, it was occupied by the Russians. The Congress of Vienna assigned the city to Prussia, and in 1822, it was made the seat of government for the Prussian Rhine Province.
After World War I, France occupied the area once again. In retaliation against the French, the German populace of the city has insisted on using the more German spelling of Koblenz since 1926. During World War II it was the location of the command of Army Group B and like many other German cities, it was heavily bombed and rebuilt afterwards. Between 1947 and 1950, it served as the seat of government of Rhineland-Palatinate.
The Rhine Gorge was declared a World Heritage Site in 2002, with Koblenz marking the northern end
