President George W. Bush appointed L. Paul Bremer III as the presidential envoy to Iraq after the U.S. invasion and overthrow of Iraq’s president, Saddam Hussein, in 2003. After arriving in Iraq, Bremer became the director of the Coalition Provisional Authority. He was the highest-ranking U.S. civilian in the country and oversaw efforts to rebuild. He describes life in the “green zone,” an area in the center of Baghdad that the coalition forces controlled.
