1560s, probably from Italian maneggiare "to handle," especially "to control a horse," ultimately from Latin noun manus "hand" (from PIE root *man- (2) "hand"). Influenced by French manège "horsemanship" (earliest English sense was of handling horses), which also was from Italian. Extended to other objects or business from 1570s. Sense of "get by" first recorded 1650s. Related: Managed; managing. Managed economy was used by 1933.
