Which event would come first in the correct sequence?

A.) Jan. 1861: Four more states secede.

B.) April 1861: The Confederacy fires on Fort Sumter and another state secedes.

C.) Nov. 1860: Abraham Lincoln is elected president.

D.) Dec. 1860: South Carolina secedes.

The correct answer is C) November of 1860: Abraham Lincoln is elected president.

The election of Abraham Lincoln is eventually going to lead to all of the other events mentioned in the answer choices. A few short weeks after Lincoln becomes president, South Carolina leaves the Union. After that, four more states will follow suit. Eventually, there will be a military conflict between the United States and the newly formed Confederate States of America at Fort Sumter in South Carolina. This results in the beginning of the American Civil War.
