The Royal Louis was a prominent ship of the line in the French Royal Navy, constructed at Toulon between 1666 and 1669 under the supervision of Rodolphe Gédéon. As a first-rate warship, she was designed to serve as a flagship, notably intended to lead the fleet in the 1669 Cretan campaign for François de Bourbon-Vendome, Duc de Beaufort. However, she was not ready in time for that mission and did not see active service until 1677. Her construction resulted in a formidable vessel, initially armed with a substantial complement of 24-pounder guns. During a rebuild at Toulon from December 1676 to April 1677, her armament was upgraded: four 24-pounders on the lower deck were replaced with four 36-pounders, two additional 18-pounders were added on the middle deck, and two 6-pounders were removed from her quarterdeck, maintaining her total at 104 guns. This rearmament enhanced her firepower and combat capability. In May 1677, under the command of Abraham Duquesne, Royal Louis sailed from Toulon to Messina, Sicily, leading a small squadron to support local rebels opposing Spanish rule. After her deployment there, she returned to Toulon and remained inactive in service until 1691. The ship was described in 1683 by English naval engineer Edmund Dummer as "a great ship and glorious in her first carving," though he criticized her proportion and workmanship, expressing doubts about her underwater and overall design. The Royal Louis was decommissioned in 1691, and by 1697, she was taken apart at Toulon, replaced by a new First Rank ship bearing the same name. Her service history reflects her role as a significant maritime asset of France during her era, representing the power and naval ambitions of the French fleet in the late 17th century.
