Final answer:
Abraham Lincoln's position on emancipating enslaved Blacks evolved over time. Initially cautious, he eventually embraced emancipation as a war measure and issued the Emancipation Proclamation in 1862.
Step-by-step explanation:
Abraham Lincoln's position on emancipating enslaved Blacks evolved over time. In the beginning, Lincoln did not initially support the idea of emancipation and was cautious about taking any action that could potentially lose the support of the Border States. However, as the war progressed and the Union cause flagged, Lincoln began to embrace emancipation as a war measure. In 1862, he issued the Emancipation Proclamation, which declared that all enslaved people in Confederate territory were to be set free. While Lincoln's views may have changed, it is important to note that he did not always support immediate unconditional emancipation from the start.
