Nonetheless, the diverse Indian societies of North America did share certain common characteristics. Their lives were steeped in religious ceremonies often directly related to farming and hunting. Spiritual power, they believed, suffused the world, and sacred spirits could be found in all kinds of living and inanimate things—animals, plants, trees, water, and wind. Through religious ceremonies, they aimed to harness the aid of powerful supernatural forces to serve the interests of man. In some tribes, hunters performed rituals to placate the spirits of animals they had killed. Other religious ceremonies sought to engage the spiritual power of nature to secure abundant crops or fend off evil spirits. Indian villages also held elaborate religious rites, participation in which helped to define the boundaries of community membership. In all Indian societies, those who seemed to possess special abilities to invoke supernatural powers—shamans, medicine men, and other religious leaders—held positions of respect and authority.
Indian religion did not pose a sharp distinction between the natural and the supernatural, or secular and religious activities. In some respects, however, Indian religion was not that different from popular spiritual beliefs in Europe. Most Indians held that a single Creator stood atop the spiritual hierarchy. Nonetheless, nearly all Europeans arriving in the New World quickly concluded that Indians were in dire need of being converted to a true, Christian faith.
