Sundancer dancing on hill

The Sun Dance (or Sundance) is a religious ceremony practiced by a number of Native American and First Nations peoples, primarily those of the Plains Nations. Each tribe has its own distinct practices and ceremonial protocols. Many of the ceremonies have features in common, such as specific dances and songs passed down through many generations, the use of traditional drums, the sacred pipe, tobacco offerings, praying, fasting and, in some cases, the piercing of skin on the chest or back for the men and arms for the women.
The Aztec people were certain ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl language and who dominated large parts of Mesoamerica from the 14th to 16th centuries.
The Maya is a Mesoamerican civilization, noted for the only known fully developed written language of the pre-Columbian Americas, as well as for its art, architecture, and mathematical and astronomical systems.
