Those facts alone help explain why the Deep South was so eager to secede completely, the Upper South less eager and never completely, and the Border South refused to formally secede, sending more troops to the Union than Confederacy.
As for the effects of Lincoln's 1862 Emancipation Proclamation, at the time it originally effected only about 50,000 slaves, but by war's end, in 1865, around three million were freed by the Union Army.
By the year-end of 1865 the 13th Amendment freed all remaining slaves, North and South.
So, while clearly you think you have an important argument here, once understood, your claims make no sense.
Your idea of the word ‘civil” is, like all your other arguments so totally blind and one sided that you can’t as I’ve mentioned before, open your eyes to anything else beyond your narrow perception which is known as “Tunnel Vision.”
Your use of “Total population is a sly way of avoiding and altering the overall effect of Lincoln’s Emancipation Proclamation which was dated in JANUARY 1863, well after the beginning of the war.
Your sources and mine do not agree. I’ll leave it at that.
