Louis XIV claimed that the Spanish dowry of his wife Maria Theresa of Spain had not been paid, providing a pretext to expand French territory northward and eastward. He invaded the Spanish Netherlands, initiating the War of Devolution against Spain. French forces had already seized Charleroi, Tournai, and Douai before advancing on Lille.
French forces under Louis XIV besieged Lille, then part of the Spanish-ruled county of Flanders, from 28 August to 26 September 1667. The siege was the only major engagement of the War of Devolution and was conducted using innovative techniques developed by the military engineer Vauban, which proved decisive in the city's capture.
Lille fell to France, representing the first significant victory achieved through Vauban's systematic siege methods. The capture established Vauban's approach as a model for future French military engineering and expanded French control along its northern border at the expense of the Spanish Netherlands.
