Barack Obama
Barack Obama served as the 44th President of the United States from 2009 to 2017, becoming the first African American to hold the office.
Obama worked as a community organizer and civil rights attorney in Chicago before entering politics, serving in the Illinois State Senate and then the U.S. Senate before his historic 2008 presidential campaign.
As president, Obama's major achievements included the Affordable Care Act, a sweeping healthcare reform law, and the response to the 2008 financial crisis, alongside foreign policy actions including the operation that killed Osama bin Laden in 2011.
Obama was awarded the Nobel Peace Prize in 2009, early in his presidency, and remains an influential public figure through his post-presidency writing and advocacy work.
