How does President Lincoln's night at Fords's Theater relate to the Civil War?ho it relates to the civil war

President Lincoln's night at Ford's Theater is, of course,
relevant because that was the night on which he was assassinated.  Because the killing
happened after the Civil War was over, it did not really have any effect on the war
itself.

The relationship between the two is that Lincoln
was killed because of his actions during the Civil War.  John Wilkes Booth was angry
about the ways in which Lincoln had helped to defeat the South in the war.  Booth was
bitter about the fact that the South had lost and he wanted to take
revenge.

So Pres. Lincoln's was killed because of the Civil
War, but his death had no impact on that war.
