Good question. Officially, it was addressed to the state governors of the Confederacy - in other words, the very people who did not report to Congress at all. In reality, it was addressed to Britain and France, declaring that the war was now a crusade against slavery, and that free nations abroad could not aid the South without looking pro-slavery themselves. It was totally successful in keeping Britain and France out of the war.

before the civil war, Alabama was a slavery state.
