While oceangoing vessels were tailored to the formidable currents and unpredictable conditions of the Atlantic, Pacific, and other larger oceans, the calmer waters of the Mediterranean Sea demanded different emphases: speed, maneuverability, and even integrity to withstand ramming other ships. These galleys, the descendants of the warships of Antiquity and the Middle Ages, were mainstays in the conflicts between European states and the Ottoman Empire. Their most famous usage was at the 1571 Battle of Lepanto, but they were versatile beyond pitched battle. The Knights Hospitaller of Malta organized the so-called "corso", which was designed for the dual purpose of protecting trade routes against piracy and raiding rival shipping enterprises. The term carried such gravity that it was even variously applied over time to smaller units of the system or even individual figures.
