Native Americans in the United States

Native Americans, also known as American Indians, Indians, Indigenous Americans and other terms, are the indigenous peoples of the United States. There are over 500 federally recognized tribes within the U.S., about half of which are associated with Indian reservations. The term excludes Native Hawaiians and some Alaska Natives.
The ancestors of modern Native Americans arrived in what is now the United States at least 15,000 years ago, possibly much earlier, from Asia through Beringia. A vast variety of peoples, societies and cultures subsequently developed. Native Americans were greatly affected by the European colonization of the Americas, which began in 1492, and their population declined precipitously due to introduced diseases, warfare, and slavery. After the founding of the United States, many Native American peoples were subjected to warfare, removals, and one-sided treaties, and they continue to suffer from discriminatory government policies today. Since the 1960s, Native American self-determinationmovements have resulted in many changes to the lives of Native Americans, though there are still many contemporary issues faced by Native Americans. Today, there are over five million Native Americans in the United States.
