Assassination of John F. Kennedy

John F. Kennedy was assassinated in Dallas, Texas, by Lee Harvey Oswald, who fired from the Texas School Book Depository. Kennedy was pronounced dead shortly after, and Vice President Lyndon B. Johnson was sworn in as president. Oswald was arrested but was killed by Jack Ruby before trial. The Warren Commission concluded Oswald acted alone, but later investigations raised the possibility of a conspiracy. The event remains a subject of debate and profoundly shaped U.S. history.
