How did the emancipation proclamation become a turning point in the civil war? a) the war became less important to northerners. b) the war was now officially about slavery. c) the war now reached across the country. d) the war became less important to southerners.

The correct answer is B. The Emancipation Proclamation became a turning point in the Civil War, as after this event, the war was officially about slavery.

The Emancipation Proclamation expanded the objectives of the Civil War. While slavery had been a major problem that led to war, Lincoln's only mission at the beginning of it was to maintain the Union. The Emancipation Proclamation made slaves an explicit objective of the Union's war effort. Establishing the abolition of slavery as one of the two main objectives of war served to deter the intervention of Britain and France.
