The 16th President of the United States was shot dead at the theatre by well-known stage actor John Wilkes Booth on April 14, 1865.
David Herold, Lewis Powell, George Atzerodt and Mary Surratt were executed for their role in the assassination.
Michael O'Laughlen, Samuel Arnold, Samuel Mudd and Edmund Spangler were imprisoned.
Each conspirator was assigned a different role in the comprehensive assassination attempt of several high-profile government members.
Edmund Spangler helped Booth escape but he was spared death because he didn't know about the assassination in advance. Booth was shot by Union forces after a dramatic 12-day manhunt led by David Herold.
Powell had been responsible for the bungled assassination attempt of the Secretary of State, William Seward on the same night.

Atzerodt had been planning an attempt of the life of the Vice President, Andrew Johnson, but is said to have lost his nerve.
The conspirators met in a Washington boarding house owned by Mary Surratt.
The trial of the conspirators ended on June 30 with Surratt, Powell, Herold, and Atzerodt all sentenced to death.
They were given a military trial as opposed to a civilian one, though, with much controversy over the way in which it was handled.
