In 1249�1254, Koblenz was given new walls by Archbishop Arnold II of Isenburg; and it was partly to overawe the turbulent townsmen that successive archbishops built and strengthened the fortress of Ehrenbreitstein that still dominates the city.
The city was a member of the league of the Rhenish cities which rose in the 13th century. The Teutonic Knights founded the Bailiwick of Koblenz in or around 1231. Koblenz attained great prosperity and it continued to advance until the disaster of the Thirty Years' War brought about a rapid decline. After Philip Christopher, elector of Trier, surrendered Ehrenbreitstein to the French, the town received an imperial garrison in 1632.

Among the many royalist French refugees who flooded into the city were Louis XVI's two younger brothers, the Comte de Provence and the Comte d'Artois. In addition, Louis XVI's cousin, the Prince
