Indigenous peoples of the Americas

In the Americas, Indigenous peoples comprise the two continents' pre-Columbian inhabitants, as well as the ethnic groups that identify with them in the 15th century, as well as the ethnic groups that identify with the pre-Columbian population of the Americas as such. These populations exhibit significant diversity; some Indigenous peoples were historically hunter-gatherers, while others practiced agriculture and aquaculture. Various Indigenous societies developed complex social structures, including pre-contact monumental architecture, organized cities, city-states, chiefdoms, states, kingdoms, republics, confederacies, and empires. These societies possessed varying levels of knowledge in fields such as engineering, architecture, mathematics, astronomy, writing, physics, medicine, agriculture, irrigation, geology, mining, metallurgy, art, sculpture, and goldsmithing.

Indigenous peoples continue to inhabit many regions of the Americas, with significant populations in countries such as Bolivia, Canada, Chile, Colombia, Ecuador, Guatemala, Mexico, Peru, and the United States. There are at least 1,000 different indigenous languages spoken across the Americas, with 574 federally recognized tribes in the United States alone. Some languages, including Quechua, Arawak, Aymara, Guaraní, Nahuatl, and some Mayan languages, have millions of speakers and are recognized as official by governments in Bolivia, Peru, Paraguay, and Greenland. Indigenous peoples, whether residing in rural or urban areas, often maintain aspects of their cultural practices, including religion, social organization, and subsistence practices. Over time, these cultures have evolved, preserving traditional customs while adapting to modern needs. Some Indigenous groups remain relatively isolated from Western culture, with some still classified as uncontacted peoples.
