Barack Obama

Barack Hussein Obama II (born August 4, 1961) is an American politician who served as the 44th president of the United States from 2009 to 2017. As a member of the Democratic Party, he was the first African-American  president in U.S. history. Obama previously served as a U.S. senator representing Illinois from 2005 to 2008 and as an Illinois state senator from 1997 to 2004.
Obama was born in Honolulu, Hawaii. He graduated from Columbia University in 1983 with a Bachelor of Arts degree in political science and later 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. He became a civil rights attorney and an academic, teaching constitutional law at the University of Chicago Law School from 1992 to 2004. He also went into elective politics; Obama represented the 13th district in the Illinois Senate from 1997 until 2004, when he successfully ran for the U.S. Senate. In the 2008 presidential election, after a close primary campaign against Hillary Clinton, he was nominated by the Democratic Party for president. Obama selected Joe Biden as his running mate and defeated Republican nominee John McCain.
Obama was named the 2009 Nobel Peace Prize laureate, a decision that drew a mixture of criticism and praise. His first-term actions addressed the global financial crisis and included a major stimulus package to guide the economy in recovering from the Great Recession, a partial extension of George W. Bush's tax cuts, legislation to reform health care, a major financial regulation reform bill, and the end of a major U.S. military presence in Iraq. Obama also appointed Supreme Court justices Sonia Sotomayor and Elena Kagan, the former being the first Hispanic American on the Supreme Court. He ordered Operation Neptune Spear, the raid that killed Osama bin Laden, who was responsible for the September 11 attacks. Obama downplayed Bush's counterinsurgency model, expanding air strikes and making extensive use of special forces, while encouraging greater reliance on host-government militaries. He also ordered military involvement in Libya in order to implement UN Security Council Resolution 1973, contributing to the overthrow of Muammar Gaddafi.
Obama defeated Republican opponent Mitt Romney in the 2012 presidential election. In his second term, the American economy continued to improve significantly. Obama took steps to combat climate change, signing a major international climate agreement and an executive order to limit carbon emissions. Obama also presided over the implementation of the Affordable Care Act and other legislation passed in his first term. He negotiated a nuclear agreement with Iran and normalized relations with Cuba. The number of American soldiers in Afghanistan fell dramatically during Obama's second term, though U.S. soldiers remained in the country throughout Obama's presidency. Obama promoted inclusion for LGBT Americans, becoming the first sitting U.S. president to publicly support same-sex marriage.
Obama left office on January 20, 2017, and continues to reside in Washington, D.C. His presidential library in the South Side of Chicago began construction in 2021. Since leaving office, Obama has remained politically active, campaigning for candidates in various American elections, including Biden's successful presidential bid in 2020 and Biden's re-election bid in 2024. Outside of politics, Obama has published three books: Dreams from My Father (1995), The Audacity of Hope (2006), and A Promised Land (2020). Historians and political scientists rank Obama among the upper tier in historical rankings of American presidents.
