1. Why was the concept of believing in one god so profound?

When monotheism first became an idea it was really different and in some cases shocking to what they people at the time believed, they believed in many gods for different things, so the fact that some people believed in only one God was surprising but also in a way seemed like a good deal to some as they only had to focus on 1 supreme being. As we also know, religions with only one God seem to still be around and be stronger than those with many. (sometimes, not always.)

the emancipation proclamation was the aim of the war change to include the freeing of slaves in addition to preserving the union. the 13th amendment, which abolished slavery in the u.s. was passed on december 6th 1865.

as promised, lincoln waited to unveil the proclamation until he could do so with success from the union military advance. on september 22nd 1862, after a victory at antietam, he publicly announced a preliminary emancipation proclamation, declaring all slaves free in the rebellious states as of january 1st 1863.
