The Plains Indians were skilled farmers and artists who lived in organized tribes, each with their own unique language. The introduction of horses by the Spanish allowed them to more easily hunt buffalo and follow migrating herds. Their most important religious ceremony, the Sun Dance, involved dancing, singing, praying, drumming and visions to show the cyclical nature of life. Women supervised home life, gathered food, and passed down oral traditions, while men protected the village, led hunts and wars, and oversaw spiritual practices.
