Who assassinated President Abraham Lincoln?

The assassination of President Abraham Lincoln was carried out by John Wilkes Booth, who was a well-known actor and a Confederate supporter. On April 14, 1865, Booth shot Lincoln at Ford's Theatre in Washington, D.C., as a means to destabilize the Union government following the end of the Civil War and to avenge the Confederacy. After the assassination, Booth fled the scene and was pursued by Union soldiers for several days, marking a significant moment in American history due to the immediate impact it had on the nation and its leadership.

The other individuals mentioned, such as Lee Harvey Oswald, who assassinated President John F. Kennedy; James Earl Ray, who killed Dr. Martin Luther King Jr.; and Charles Guiteau, who was responsible for the assassination of President James A. Garfield, are associated with different assassinations in American history. This distinction highlights the unique historical context surrounding Lincoln's assassination and Booth's motivation, making it clear why Booth is the correct answer.
