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 via Beringia.
Iroquois Culture: The Iroquois League of Nations or "People of the Long House", based in present-day upstate and western New York, had a confederacy model from the mid-15th century. It has been suggested that their culture contributed to political thinking during the development of the later United States government. Their system of affiliation was a kind of federation, different from the strong, centralized European monarchies.Leadership was restricted to a group of 50 sachem chiefs, each representing one clan within a tribe. The Oneida and Mohawk people had nine seats each; the Onondagas held fourteen; the Cayuga had ten seats; and the Seneca had eight. Representation was not based on population numbers, as the Seneca tribe greatly outnumbered the others. When a sachem chief died, his successor was chosen by the senior woman of his tribe in consultation with other female members of the clan; property and hereditary leadership were passed matrilineally. Decisions were not made through voting but through consensus decision making, with each sachem chief holding theoretical veto power. The Onondaga were the "firekeepers", responsible for raising topics to be discussed. They occupied one side of a three-sided fire (the Mohawk and Seneca sat on one side of the fire, the Oneida and Cayuga sat on the third side.) Elizabeth Tooker, an anthropologist, has said that it was unlikely the US founding fathers were inspired by the confederacy, as it bears little resemblance to the system of governance adopted in the United States. For example, it is based on inherited rather than elected leadership, selected by female members of the tribes, consensus decision-making regardless of population size of the tribes, and a single group capable of bringing matters before the legislative body. Long-distance trading did not prevent warfare and displacement among the indigenous peoples, and their oral histories tell of numerous migrations to the historic territories where Europeans encountered them. The Iroquois invaded and attacked tribes in the Ohio River area of present-day Kentucky and claimed the hunting grounds. Historians have placed these events as occurring as early as the 13th century, or in the 17th century Beaver Wars. Through warfare, the Iroquois drove several tribes to migrate west to what became known as their historically traditional lands west of the Mississippi River. Tribes originating in the Ohio Valley who moved west included the Osage, Kaw, Ponca and Omaha people. By the mid-17th century, they had resettled in their historical lands in present-day Kansas, Nebraska, Arkansas and Oklahoma. The Osage warred with Caddo-speaking Native Americans, displacing them in turn by the mid-18th century and dominating their new historical territories.

Did they do anything to change history or become well known for?

the Iroquois drove several tribes to migrate west to what became known as their historically traditional lands

Spielberg was born on December 18, 1946 in Cincinnati, Ohio. His mother, Leah (nee Posner, later Adler; January 12, 1920 - February 21, 2017), was a restaurateur and concert pianist, and his father, Arnold Spielberg (born 1917), was an electrical engineer involved in the development of computers. His family was Orthodox Jewish. Spielberg's paternal grandparents were Jewish Ukrainian immigrants who settled in Cincinnati in the 1900s; his grandmother was from Sudylkiv, while his grandfather was from Kamianets-Podilskyi.
A collector of film memorabilia, Spielberg purchased a balsa Rosebud sled from Citizen Kane (1941) in 1982. He bought Orson Welles's own directorial copy of the script for the radio broadcast The War of the Worlds (1938) in 1994. Spielberg has purchased Academy Award statuettes being sold on the open market and donated them to the Academy of Motion Picture Arts and Sciences, to prevent their further commercial exploitation. His donations include the Oscars that Bette Davis received for Dangerous (1935) and Jezebel (1938), and Clark Gable's Oscar for It Happened One Night (1934). Spielberg is a major collector of the work of American illustrator and painter Norman Rockwell. A collection of 57 Rockwell paintings and drawings owned by Spielberg and fellow Rockwell collector and film director George Lucas were displayed at the Smithsonian American Art Museum July 2, 2010 - January 2, 2011, in an exhibition titled Telling Stories. Spielberg is an avid film buff, and, when not shooting a picture, he will watch many films in a single weekend. He sees almost every major summer blockbuster in theaters if not preoccupied and enjoys most of them. Since playing Pong while filming Jaws in 1974, Spielberg has been an avid video gamer. Spielberg played many of LucasArts adventure games, including the first Monkey Island games. He owns a Wii, a PlayStation 3, a PSP and Xbox 360, and enjoys playing first-person shooters such as the Medal of Honor series and Call of Duty 4: Modern Warfare. He has also criticized the use of cutscenes in games, calling them intrusive, and feels making story flow naturally into the gameplay is a challenge for future game developers.

Did he purchase any other film relics?
He bought Orson Welles's own directorial copy of the script for the radio broadcast The War of the Worlds (1938) in 1994.
