President Abraham Lincoln was assassinated on April 14, 1865, while attending a play at Ford's Theatre in Washington, D.C.
The assassin was John Wilkes Booth, a famous actor and southern sympathizer who opposed Lincoln's policies, particularly his efforts to abolish slavery in the United States.
Booth entered the President's box and shot him in the head, before jumping onto the stage and shouting, "Sic semper tyrannis!" ("Thus always to tyrants!") Booth then fled the scene and went into hiding, but was later tracked down by Union troops and killed.
Eight other people were implicated in the assassination conspiracy and four were hanged, while Booth remains a controversial figure in American history, regarded by some as a hero and others as a traitor and assassin.
