What was Lincoln's main reason for starting the Civil War? Please explain your answer fully. ( hint: It was not to end slavery)

 His main reasoning for going through with the civil war was to preserve the Union, and to unify the United States as a whole also called the Reconstruction Era.

Explanation:

A quote from he when he was asked about his reasons was this, "If I could save the Union without freeing any slave I would do it, and if I could save it by freeing all slaves I would do it." This was the first phase of the war, then it eventually spread to the South where slaves were just hearing of the news. The men of color were practically forcing the army to allow them to enlist as it became a fight for freedom. During it's final part Lincoln's goal had become to try and create a nation not divided by differing ideals, and instead a place where a person is a person.

This is mainly from information that I've gathered, so I'm sorry if I got anything wrong.

according to the quotation from booker t. washington's 1895 atlanta compromise speech.

in the great leap from slavery to freedom . . the masses of us are to live by the production of our hands . . we shall prosper . . as we learn to dignify and glorify common labor.

washington believed that  hard work had its own kind of dignity.
