Final answer:
In the Gettysburg Address, Abraham Lincoln did not mention abolishing slavery as a goal for fighting the Civil War; instead, he focused on the ideals of freedom and equality, as well as honoring the soldiers who fought in the Battle of Gettysburg.
Step-by-step explanation:
The item NOT mentioned in the Gettysburg Address is abolishing slavery as a goal for fighting the Civil War. President Abraham Lincoln's Gettysburg Address, delivered during the American Civil War at the dedication of the Soldiers' National Cemetery in Gettysburg, Pennsylvania, invoked the spirit of the American Revolution and referenced the Founding Fathers. It emphasized the guarantee of freedom and the idea of equality, declaring the Civil War a test of whether a nation conceived in liberty could survive.
However, despite Lincoln's personal antipathy towards slavery, the explicit goal of abolishing slavery was not a part of this particular speech. It wasn't until the Emancipation Proclamation and later developments in the war that abolition became a central Union war aim.
