Still took over half a century and the bloodiest war in the country's history against those very Virginian politicians to end slavery, though, didn't it?

It took the war and the subsequent occupation to finally stamp it out. There was nothing gradual about the Civil War and its effects.The cotton gin was invented several years after the ratification of the US Constitution, though.
