Assassination of John F. Kennedy
Encyclopedia Britannica
Assassination of John F. Kennedy, mortal shooting of John F. Kennedy, the 35th president of the United States, as he rode in a motorcade in Dallas, Texas, on November 22, 1963. His accused killer was Lee Harvey Oswald, a former U.S. Marine who had embraced Marxism and defected for a time to the Soviet Union. Oswald never stood trial for murder, because, while being transferred after having been taken into custody, he was shot and killed by Jack Ruby, a distraught Dallas nightclub owner.
