You pick up very well-known books on Lincoln [and] you will find almost no reference to his long-term belief in colonization. Why? Because it doesn't fit the image of the Great Emancipator. It doesn't fit the retrospective view we want to have of Lincoln as the man who was the moralist in politics, who came into office committed to ending slavery and waited to sign this document.

Lincoln was a modernizer, so to speak. He believed in economic development. As a Whig before the war he favored what we would call infrastructure spending, government appropriation for canals, railroads, river and harbor improvements, and a tariff to protect industry. He believed in this market revolution that was sweeping across Northern society. He himself benefited from it in his own life.

Whenever you think of Lincoln as a historian, in his own mind, he becomes the Great Emancipator. This is his role in history henceforth. He was an ambitious man who wanted to make an impact on history, and this is how he did it.

Freedom has been privatized - it is how you dress, what your sexual orientation is, choosing your own life. That's fine. But that is not what Thomas Jefferson was talking about.

Lincoln has accepted America as a biracial society. He's talking about giving at least some black men the right to vote. In the Emancipation Proclamation he advises some blacks to labor faithfully for reasonable wages, here in the United States. He doesn't say anything about them leaving the country. He puts black men in the army. That is a whole different vision than simply saying "let's have them go out of the country." I think what's interesting is the change in Lincoln's view, but one must realize that he did adhere to this idea of colonization for many years.

Colonization was the idea that once slavery ended African-Americans should be encouraged - or required, in some people's view - required to leave the country. It's part of an attitude toward the abolition of slavery which says America should not be a slave society, but it can never be a multiracial society. You can never have free black and white people living together.

Who owns history? Everyone and no one--which is why the study of the past is a constantly evolving, never-ending journey of discovery.
