Answer:
Well, Your best answer will be is D. After the end of the Civil War. Because, Abe Lincoln was assassinated by John Wilkes Booth less than a week after the end of the Civil War. This dramatically changed the outcome of American history, as Andrew Johnson would now be in charge of reuniting the nation after the brutal Civil War. Johnson's presidency would be filled with turmoil and scandal, as he is almost removed from office after an impeachment trial took place in Congress.
Good Luck!
