What were the founders really afraid of?

By the time the Constitution was ratified, hundreds of substantial slave uprisings had occurred across the South. Blacks outnumbered whites in large areas, and the state militias were used to both prevent and to put down slave uprisings. As Dr. Bogus points out, slavery can only exist in the context of a police state, and the enforcement of that police state was the explicit job of the militias.

If the anti-slavery folks in the North had figured out a way to disband - or even move out of the state - those southern militias, the police state of the South would collapse. And, similarly, if the North were to invite into military service the slaves of the South, then they could be emancipated, which would collapse the institution of slavery, and the southern economic and social systems, altogether.

These two possibilities worried southerners like James Monroe, George Mason (who owned over 300 slaves) and the southern Christian evangelical, Patrick Henry (who opposed slavery on principle, but also opposed freeing slaves).

Their main concern was that Article 1, Section 8 of the newly-proposed Constitution, which gave the federal government the power to raise and supervise a militia, could also allow that federal militia to subsume their state militias and change them from slavery-enforcing institutions into something that could even, one day, free the slaves.

This was not an imagined threat. Famously, 12 years earlier, during the lead-up to the Revolutionary War, Lord Dunsmore offered freedom to slaves who could escape and join his forces. "Liberty to Slaves" was stitched onto their jacket pocket flaps. During the War, British General Henry Clinton extended the practice in 1779. And numerous freed slaves served in General Washington's army.

Thus, southern legislators and plantation owners lived not just in fear of their own slaves rebelling, but also in fear that their slaves could be emancipated through military service.

At the ratifying convention in Virginia in 1788, Henry laid it out:

"Let me here call your attention to that part [Article 1, Section 8 of the proposed Constitution] which gives the Congress power to provide for organizing, arming, and disciplining the militia, and for governing such part of them as may be employed in the service of the United States. . . .

"By this, sir, you see that their control over our last and best defence is unlimited. If they neglect or refuse to discipline or arm our militia, they will be useless: the states can do neither . . . this power being exclusively given to Congress. The power of appointing officers over men not disciplined or armed is ridiculous; so that this pretended little remains of power left to the states may, at the pleasure of Congress, be rendered nugatory."

Henry then bluntly laid it out:

"If the country be invaded, a state may go to war, but cannot suppress [slave] insurrections [under this new Constitution]. If there should happen an insurrection of slaves, the country cannot be said to be invaded. They cannot, therefore, suppress it without the interposition of Congress . . . . Congress, and Congress only [under this new Constitution], can call forth the militia."

And why was that such a concern for Patrick Henry?

"In this state," he said, "there are two hundred and thirty-six thousand blacks, and there are many in several other states. But there are few or none in the Northern States. . . . May Congress not say, that every black man must fight? Did we not see a little of this last war? We were not so hard pushed as to make emancipation general; but acts of Assembly passed that every slave who would go to the army should be free."

So Madison, who had (at Jefferson's insistence) already begun to prepare proposed amendments to the Constitution, changed his first draft of one that addressed the militia issue to make sure it was unambiguous that the southern states could maintain their slave patrol militias.

His first draft for what became the Second Amendment had said: "The right of the people to keep and bear arms shall not be infringed; a well armed, and well regulated militia being the best security of a free country [emphasis mine]: but no person religiously scrupulous of bearing arms, shall be compelled to render military service in person."

But Henry, Mason and others wanted southern states to preserve their slave-patrol militias independent of the federal government. So Madison changed the word "country" to the word "state," and redrafted the Second Amendment into today's form:

"A well regulated Militia, being necessary to the security of a free State [emphasis mine], the right of the people to keep and bear Arms, shall not be infringed."
