On April 14, 1865, Abraham Lincoln, the 16th president of the United States, was assassinated by John Wilkes Booth while attending the play Our American Cousin at Ford's Theatre in Washington, D.C. Shot in the head as he watched the play, Lincoln died of his wounds the following day at 7:22 am in the Petersen House opposite the theater. He was the first U.S. president to be assassinated. His funeral and burial were marked by an extended period of national mourning. Near the end of the American Civil War, Lincoln's assassination was part of a larger conspiracy intended by Booth to revive the Confederate cause by eliminating the three most important officials of the federal government. Conspirators Lewis Powell and David Herold were assigned to kill Secretary of State William H. Seward, and George Atzerodt was tasked with killing Vice President Andrew Johnson. Beyond Lincoln's death, the plot failed: Seward was only wounded, and Johnson's would-be attacker became drunk instead of killing the vice president. After a dramatic initial escape, Booth was killed at the end of a 12-day chase. Powell, Herold, Atzerodt, and Mary Surratt were later hanged for their roles in the conspiracy. Source: Wikipedia (en)
