What was one important thing that Abraham Lincoln did?

One of the most significant achievements of Abraham Lincoln was his role in freeing the slaves in the United States. This monumental act is best represented through the Emancipation Proclamation, issued on January 1, 1863, which declared that all enslaved people in the Confederate states were to be set free. This not only shifted the focus of the Civil War towards the issue of slavery but also laid the groundwork for the eventual abolition of slavery nationwide through the 13th Amendment.

Lincoln's leadership during this transformative period in American history showcased his commitment to preserving the Union and promoting human rights. His actions helped to redefine the purpose of the war and directly contributed to the advancement of civil liberties in the United States. Thus, this aspect of his presidency is celebrated as a key moment in the struggle for freedom and equality.
