Question:
Barack Hussein Obama II ( ( listen); born August 4, 1961) is an American politician who served as the 44th President of the United States from 2009 to 2017. The first African American to assume the presidency, he was previously the junior United States Senator from Illinois from 2005 to 2008. Before that, he served in the Illinois State Senate from 1997 until 2004. Obama was born in 1961 in Honolulu, Hawaii, two years after the territory was admitted to the Union as the 50th state.
From age six to ten, Obama attended local Indonesian-language schools: Sekolah Dasar Katolik Santo Fransiskus Asisi (St. Francis of Assisi Catholic Elementary School) for two years and Sekolah Dasar Negeri Menteng 01 (State Elementary School Menteng 01/Besuki Public School) for one and a half years, supplemented by English-language Calvert School homeschooling by his mother. As a result of those four years in Jakarta, he was able to speak Indonesian fluently as a child. During his time in Indonesia, Obama's step-father taught him to be resilient and gave him "a pretty hardheaded assessment of how the world works". In 1971, Obama returned to Honolulu to live with his maternal grandparents, Madelyn and Stanley Dunham. He attended Punahou School-- a private college preparatory school-- with the aid of a scholarship from fifth grade until he graduated from high school in 1979. In his youth, Obama went by the nickname "Barry". Obama lived with his mother and half-sister, Maya Soetoro, in Hawaii for three years from 1972 to 1975 while his mother was a graduate student in anthropology at the University of Hawaii. Obama chose to stay in Hawaii with his grandparents for high school at Punahou when his mother and half-sister returned to Indonesia in 1975 so his mother could begin anthropology field work. His mother spent most of the next two decades in Indonesia, divorcing Lolo in 1980 and earning a PhD degree in 1992, before dying in 1995 in Hawaii following unsuccessful treatment for ovarian and uterine cancer. Obama later reflected on his years in Honolulu and wrote: "The opportunity that Hawaii offered - to experience a variety of cultures in a climate of mutual respect - became an integral part of my world view, and a basis for the values that I hold most dear." Obama has also written and talked about using alcohol, marijuana, and cocaine during his teenage years to "push questions of who I was out of my mind". Obama was also a member of the "choom gang", a self-named group of friends that spent time together and occasionally smoked marijuana. After graduating from high school in 1979, Obama moved to Los Angeles to attend Occidental College. In February 1981, Obama made his first public speech, calling for Occidental to participate in the disinvestment from South Africa in response to that nation's policy of apartheid. In mid-1981, Obama traveled to Indonesia to visit his mother and half-sister Maya, and visited the families of college friends in Pakistan and India for three weeks. Later in 1981, he transferred as a junior to Columbia University in New York City, where he majored in political science with a specialty in international relations and in English literature and lived off-campus on West 109th Street. He graduated with a BA degree in 1983 and worked for about a year at the Business International Corporation, where he was a financial researcher and writer, then as a project coordinator for the New York Public Interest Research Group on the City College of New York campus for three months in 1985.

Answer the question at the end by quoting:

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.

How did they contribute to the political aspects?
When a sachem chief died, his successor was chosen by the senior woman of his tribe
