Les Sables-d'Olonne (pronounced [le sabl dolɔn]) is French for "the sands of Olonne". It was founded in 1218 from Havre d'Olonne by Savary I de Mauléon, the Lord of Mauléon, Sénéchal of Poitou and prince of Talmont.^{[citation needed]} Its history is tied to the ocean for which it has served as a port and point of maritime commerce.^{[citation needed]} Louis XI separated Les Sables d'Olonne from the town of Olonne in 1472.^{[citation needed]} It became the largest cod-fishing port in France, with 14,000 inhabitants, in the 17th century.^{[citation needed]} During the French Revolution, unlike the surrounding Vendée, the city supported the Republic, and so was often besieged—unsuccessfully, because of its port.^{[citation needed]} The current local tourism industry traces its roots to bathing establishments, first begun in 1825. Rail service reached Les Sables on 29 December 1866, via the line from La Roche-sur-Yon, Bressuire, Saumur, and Tours;^{[citation needed]} express service to and from Paris would arrive in 1971.^{[citation needed]} The city's port served as a base port for American Expeditionary Forces during World War I.^[9] Germany occupied Les Sables d'Olonne during World War II^{[citation needed]} and, upon evacuation of that army at war's end, the German army made an effort to destroy the port, and mined the harbor.^{[citation needed]}
