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.
