On 22 November 1963, President John F. Kennedy was shot and killed while riding in a presidential motorcade through Dealey Plaza in Dallas, Texas. Texas Governor John Connally, seated in front of Kennedy, was also wounded. Kennedy was pronounced dead at Parkland Memorial Hospital at 1:00 PM local time.
Lee Harvey Oswald was arrested hours later at the Texas Theatre and charged with the murder. Two days later, Oswald was shot and killed by nightclub owner Jack Ruby in the Dallas Police headquarters — live on national television. The Warren Commission (1964) concluded Oswald acted alone, but conspiracy theories have proliferated ever since; polls show a majority of Americans have never believed the lone-gunman finding.
Kennedy's assassination sent shockwaves around the world and ended an era associated with Cold War optimism, the New Frontier, and the early Civil Rights coalition. Lyndon B. Johnson was sworn in as president aboard Air Force One with Jacqueline Kennedy, still wearing her bloodstained pink suit, standing at his side.
