among Algonquian (Algonquian languages)-speaking peoples of North America, the spiritual power inherent in the world generally. Manitous are also believed to be present in natural phenomena (animals, plants, geographic features, weather); they are personified as spirit-beings that interact with humans and each other and are led by the Great Manitou (Kitchi-Manitou). The word was frequently used by 19th-century and early 20th-century anthropologists in their theories of animism, a religious system characteristic of many indigenous peoples.
