Native Americans are the indigenous peoples within the boundaries of the present-day United States, including those in Alaska and Hawaii. They are composed of numerous, distinct tribes and ethnic groups, many of which survive as intact political communities. The terms used to refer to Native Americans have been controversial. According to a 1995 U.S. Census Bureau set of home interviews, most of the respondents with an expressed preference refer to themselves as "American Indians" or simply "Indians"; this term has been adopted by major newspapers and some academic groups, but does not traditionally include Native Hawaiians or certain Alaskan Natives, such as Aleut, Yup'ik, or Inuit peoples.
Since the end of the 15th century, the migration of Europeans to the Americas has led to centuries of conflict and adjustment between Old and New World societies. Many Native Americans lived as hunter-gatherer societies and told their histories by oral traditions; Europeans therefore created almost all of the surviving historical record concerning the conflict.
