The history of North America is the study of the past, particularly the written record, oral histories, and traditions, passed down from generation to generation on the continent in the Earth's northern hemisphere and (chiefly) western hemisphere.
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.
The Seneca are a group of indigenous people native to North America. They were the nation located farthest to the west within the Six Nations or Iroquois League in New York before the American Revolution. While exact population figures are unknown, approximately 15,000 to 25,000 Seneca live in Canada, near Brantford, Ontario, at the Six Nations of the Grand River First Nation. They are descendants of Seneca who resettled there, as they had been allies of the British during the American Revolution. Nearly 30,000 Seneca live in the United States, on and off reservations around Buffalo, New York and in Oklahoma.
