George W. Bush (1946-), America’s 43rd president, served in office from 2001 to 2009. Before entering the White House, Bush, the oldest son of George H.W. Bush, the 41st U.S. president, was a two-term Republican governor of Texas. A graduate of Yale University and Harvard Business School, Bush worked in the Texas oil industry and was an owner of the Texas Rangers baseball team before becoming governor. In 2000, he won the presidency after narrowly defeating Democratic challenger Al Gore. Bush’s time in office was shaped by the September 11, 2001, terrorist attacks against America. In response to the attacks, he declared a global “war on terrorism,” established the Department of Homeland Security and authorized U.S.-led wars in Afghanistan and Iraq.
