During his presidency, Abraham Lincoln faced moral dilemmas related primarily to the issue of slavery and the preservation of the Union. His commitment to ending slavery conflicted with the need to maintain the support of border states and various political factions. The Emancipation Proclamation represented a significant turning point in his approach, as it aimed to free enslaved individuals in rebelling states while upholding the political balance. Lincoln’s navigation of these challenges demonstrated his belief in equality and his dedication to a unified nation.
