Answer:
a. anti slavery
b. Abraham Lincoln
c. making abolition a war goal
Explanation:
The Emancipation Proclamation contributed in no small part to the defeat of the Confederacy in the Civil War because it gave the Union the support of the Abolitionists and the Black Americans in both the North and the South.
At a time where the Union was experiencing losses in the battlefield and Abraham Lincoln was losing support, the Abolitionists rallied behind him and gave him the support needed to push on.
The war also ensured that the European nations who might have supported the Confederacy, steered clear of the conflict as they did not want to be seen as supporting slavery.
