Barack Hussein Obama is an American politician who served as the 44th President of the United States from 2009 to 2017. He is the first African American to have served as president. He previously served in the U.S. Senate representing Illinois from 2005 to 2008 and in the Illinois State Senate from 1997 to 2004.
Obama was born in Honolulu, Hawaii, two years after the territory was admitted to the Union as the 50th state. Raised largely in Hawaii, Obama also spent one year of his childhood in Washington State and four years in Indonesia. After graduating from Columbia University in 1983, he worked as a community organizer in Chicago. In 1988 Obama enrolled in Harvard Law School, where he was the first black president of the Harvard Law Review. After graduation, he became a civil rights attorney and professor, teaching constitutional law at the University of Chicago Law School from 1992 to 2004. Obama represented the 13th District for three terms in the Illinois Senate from 1997 to 2004, when he ran for the U.S. Senate. Obama received national attention in 2004, with his unexpected March primary win, his well-received July Democratic National Convention keynote address, and his landslide November election to the Senate. In 2008, Obama was nominated for president, a year after his campaign began, and after a close primary campaign against Hillary Clinton. He was elected over Republican John McCain, and was inaugurated on January 20, 2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate.
