How did the Emancipation Proclamation serve as both a political strategy for military victory as well as a sort of public relations campaign?”

Explanation:

The Emancipation Proclamation issued by President Lincoln declared that all individuals who were held as slaves within the Confederate states shall be set free.

During the third Civil War, the declaration of the proclamation was a major military strategy as it was believed that freeing enslaved workers would greatly effect Confederate war efforts.

The proclamation also garnered a lot of attention from the public especially the abolitionists though Lincoln's primary aim was to save the Union rather than freeing the slaves.
