Answer:
<h2>This timeline of events leading to the American Civil War is a chronologically ordered list of events and issues which historians recognize as origins and causes of the American Civil War. These events are roughly divided into two periods: the first encompasses the gradual build-up over many decades of the numerous social, economic, and political issues that ultimately contributed to the war's outbreak, and the second encompasses the five-month span following the election of Abraham Lincoln as President of the United States in 1860 and culminating in the capture of Fort Sumter in April 1861.</h2>
The difference lies in interpreting the two sides of the conflict. McPherson saw the war as the war between the evil South and the good North. He was focused on the abolition of slavery and their integration into the society as free people. Horwitz on the other hand saw South not as evil but as a faction which went to war to protect its economic interests.
