As President, Lincoln's struggle to end the Civil War and preserve the nation left him deeply sympathetic to the plight of the slaves and increased his belief in the need for racial equality in America.
After seeing over 200,000 African-Americans volunteer and fight alongside Union forces, Lincoln dropped his support for plans to colonize freed slaves to Africa after the Civil War. In an 1863 speech, Lincoln stated, "there will be some black men who can remember that, with silent tongue, and clenched teeth, and steady eye, and well-poised bayonet, they have helped mankind on to this great consummation, while, I fear, there will be some white ones, unable to forget that, with malignant heart, and deceitful speech, they have strove to hinder it."
