"Though Lincoln argued that the founding fathers’ phrase “All men are created equal” applied to blacks and whites alike, this did not mean he thought they should have the same social and political rights. His views became clear during an 1858 series of debates with his opponent in the Illinois race for U.S. Senate, Stephen Douglas, who had accused him of supporting “negro equality.” In their fourth debate, at Charleston, Illinois, on September 18, 1858, Lincoln made his position clear. “I will say then that I am not, nor ever have been, in favor of bringing about in any way the social and political equality of the white and black races,” he began, going on to say that he opposed blacks having the right to vote, to serve on juries, to hold office and to intermarry with whites. What he did believe was that, like all men, blacks had the right to improve their condition in society and to enjoy the fruits of their labor. In this way they were equal to white men, and for this reason slavery was inherently unjust.
Like his views on emancipation, Lincoln’s position on social and political equality for African-Americans would evolve over the course of his presidency. In the last speech of his life, delivered on April 11, 1865, he argued for limited black suffrage, saying that any black man who had served the Union during the Civil War should have the right to vote."
