George Walker Bush ( /ˈdʒɔrdʒ ˈwɔːkər ˈbʊʃ/ (help·info); born July 6, 1946) was the 43rd President of the United States from 2001 to 2009 and the 46th Governor of Texas from 1995 to 2000.

Bush is the eldest son of George H. W. Bush (the 41st President) and Barbara Bush, making him one of only two American presidents to be the son of a preceding president. After graduating from Yale University in 1968, and Harvard Business School in 1975, Bush worked in his family's oil businesses. He married Laura Welch in 1977 and unsuccessfully ran for the United States House of Representatives shortly thereafter. He later co-owned the Texas Rangers baseball team before defeating Ann Richards in the 1994 Texas gubernatorial election. In a close and controversial election, Bush was elected President in 2000 as the Republican candidate, receiving a majority of the electoral votes while losing the popular vote to then-Vice President Al Gore.

Eight months into Bush's first term as president, the September 11, 2001, terrorist attacks occurred. In response, Bush announced a global War on Terrorism, ordered an invasion of Afghanistan that same year and an invasion of Iraq in 2003. In addition to national security issues, Bush promoted policies on the economy, health care, education, and social security reform. He signed into law broad tax cuts, the No Child Left Behind Act and Medicare prescription drug benefits for seniors. His tenure saw a national debate on immigration and Social Security.
