Who are the 4 presidents killed

Four U.S. Presidents have been assassinated while in office: Abraham Lincoln, James A. Garfield, William McKinley, and John F. Kennedy. Abraham Lincoln was shot by John Wilkes Booth at Ford's Theatre in Washington, D.C., on April 14, 1865, dying the next morning—he was killed just days after the end of the Civil War. James A. Garfield was shot by Charles J. Guiteau at a Washington railway station on July 2, 1881, and died from his wounds and infection on September 19, 1881, after suffering for more than two months. William McKinley was shot by anarchist Leon Czolgosz at the Pan-American Exposition in Buffalo, New York, on September 6, 1901, dying eight days later from gangrene caused by his wounds.

John F. Kennedy was assassinated on November 22, 1963, in Dallas, Texas, while riding in a presidential motorcade, with Lee Harvey Oswald arrested for the crime, though conspiracy theories have persisted for decades. All four assassinations profoundly impacted American history and led to significant changes in presidential security protocols. Beyond these four successful assassinations, there have been numerous other assassination attempts on U.S. presidents that failed, including attempts on Andrew Jackson, Theodore Roosevelt (after his presidency), Franklin D. Roosevelt, Harry Truman, Gerald Ford (two attempts), and Ronald Reagan, demonstrating the persistent security challenges faced by American leaders.
