Lincoln's Emancipation Proclamation Still Misunderstood

On New Year's Day in 1863, with the nation in the middle of a civil war, Abraham Lincoln signed a document that has become known as one of the most important in American history. There's been debate about the Emancipation Proclamation over the years, and a good bit of fuzziness in the popular consciousness about what it did and didn't do, and just how much Lincoln himself was responsible for toppling the institution of slavery.
