Answer: Events just before the Lincoln assassination.
Step-by-step explanation:
The assassin of President Lincoln during the Civil War was an advocate of ideas proclaimed by the Confederacy. Booth believed that the US president was a tyrant and did not accept the fact that the Union had won the war. The presidential killer was a talented actor but of racist ideals. To retaliate after the Civil War, Booth devised a plot and, with the help of senior government officials, including Vice President Andrew Johnson, devised a plan to liquidate Abraham Lincoln.
After learning that the president was going to attend the show on April 14, 1865, they decided to liquidate America's, first man. Lincoln was shot in the back of the head. Booth was arrested and killed a few days later and the others involved in the plot were hanged.
