1690s, from French marauder (17c.), from Middle French maraud "rascal" (15c.), of unknown origin, perhaps from French dialectal maraud "tomcat," echoic of its cry. A word popularized in several languages during the Thirty Years' War (Spanish merodear, German marodiren, marodieren "to maraud," marodebruder "straggler, deserter") by punning association with Count Mérode, imperialist general. Related: Marauded; marauding.
