This presentation covers the genesis, the preparation, the promulgation, the interpretations and the effects of the Emancipation Proclamation, perhaps the strangest document in American history. Discussed are the moral imperatives that inspired the war measure as well as the more concrete motives of preventing foreign intervention in the war and depleting Southern manpower—the engine that drove the Southern economy—and, the opposite side of the same coin, increasing Northern manpower, especially in Union armies. Also discussed are the Thirteenth Amendment and how the two documents were viewed by later generations of African-Americans.
