The National Commission on Terrorist Attacks Upon the United States, also known as the 9/11 Commission, was set up on November 27, 2002, "to prepare a full and complete account of the circumstances surrounding the September 11 attacks", including preparedness for and the immediate response to the attacks. The commission was also mandated to provide recommendations designed to guard against future attacks. After the publication of its final report, the commission closed on August 21, 2004. The commission's website was shut down, but has been archived.
