King Louis XIV was determined to make France a major sea power. In 1660, his Minister Jean-Baptiste Colbert ordered Sébastien Le Prestre de Vauban to build a new arsenal and to fortify the town. In 1707, during the War of the Spanish Succession, Toulon successfully resisted a siege by the Imperial Army led by Duke Victor Amadeus II of Sardinia of Savoy and Prince Eugene. However, in 1720, the city was ravaged by the black plague, coming from Marseille. Thirteen thousand people, or half the population, died.
