Barack Obama (born August 4, 1961) is the 44th President of the United States. He is the first African American to hold the office. Born in Honolulu, Hawaii, Obama is a graduate of Columbia University and Harvard Law School, where he was president of the Harvard Law Review. He served three terms representing the 13th District in the Illinois Senate from 1997 to 2004, running unsuccessfully for the United States House of Representatives in 2000. He began his presidential campaign in 2007, and in 2008, after a close primary campaign against Hillary Clinton, he won sufficient delegates in the Democratic party primaries to receive the presidential nomination. He then defeated Republican nominee John McCain in the general election, and was inaugurated as president on January 20, 2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate. In foreign policy, Obama ended U.S. military involvement in the Iraq War, increased troop levels in Afghanistan, signed the New START arms control treaty with Russia, ordered U.S. military involvement in Libya, and ordered the military operation that resulted in the death of Osama bin Laden.
