What was the origin of our slave population? The evil commenced when we were in our Colonial state, but acts were passed by our Colonial Legislature, prohibiting the importation, of more slaves, into the Colony. These were rejected by the Crown. We declared our independence, and the prohibition of a further importation was among the first acts of state sovereignty. Virginia was the first state which instructed her delegates to declare the colonies independent. She braved all dangers. From Quebec to Boston, and from Boston to Savannah, Virginia shed the blood of her sons. No imputation then can be cast upon her in this matter. She did all that was in her power to do, to prevent the extension of slavery, and to mitigate its evils.
