Question #1 answer:

Question #2 answer:
- ended British and French support for the South.
Context/explanation:
While Lincoln personally was strongly against slavery, he had to tread carefully in his role as president and commander-in-chief. As The History Channel points out, Lincoln was "worried about the support of the four border slave states." Those border states, which remained in the Union though they were states that permitted slavery, were Maryland, Missouri, Delaware, and Kentucky. Lincoln wanted to keep those states loyal to the Union cause.
According to the American Battlefield Trust, "Britain and France had considered supporting the Confederacy in order to expand their influence in the Western Hemisphere. However, many Europeans were against slavery." So making the war to preserve the Union specifically also about slavery was a way of blocking British and French involvement. Britain had abolished slavery in its territories in 1833. France had put a final end to slavery in its territories in 1848. So when Lincoln issued the Emancipation Proclamation on January 1, 1863, it also served as a foreign policy action to keep European powers out of the US Civil War, according to Steve Jones, professor of history at Southwestern Adventist University.
