What did Abraham Lincoln do second?

After being elected as the 16th President of the United States in 1860, Abraham Lincoln's second major action was to address the secession of Southern states. Following South Carolina's secession in December 1860, Lincoln sought to preserve the Union, leading to the outbreak of the Civil War in April 1861. He then focused on military strategies and issuing the Emancipation Proclamation in 1863, which declared the freedom of enslaved people in Confederate-held territory.
