Benjamin Franklin explained that this separation from Britain was necessary since every attempt among the Colonies to end slavery had been thwarted or reversed by the British Crown. In fact, in the years following America's separation from Great Britain, many of the Founding Fathers who had owned slaves released them (e.g., John Dickinson, Ceasar Rodney, William Livingston, George Washington, George Wythe, John Randolph, and others).
It is true, however, that not all of the Founders from the South opposed slavery. According to the testimony of Thomas Jefferson, John Rutledge, and James Madison, those from North Carolina, South Carolina, and Georgia favored slavery.
Nevertheless, despite the support in those states for slavery, the clear majority of the Founders was opposed to this evil—and their support went beyond words.
For example, in 1774, Benjamin Franklin and Benjamin Rush founded America's first antislavery society; John Jay was president of a similar society in New York. When
Constitution signer William Livingston heard of the New York society, he, as Governor of New Jersey, wrote them, offering:
“I would most ardently wish to become a member of it [the society in New York] and… I can safely promise them that neither my tongue, nor my pen, nor purse shall be wanting to promote the abolition of what to me appears so inconsistent with humanity and Christianity… May the great and the equal Father of the human race, who has expressly declared His abhorrence of oppression, and that He is no respecter of persons, succeed a design so laudably calculated to undo the heavy burdens, to let the oppressed go free, and to break every yoke.”
Other prominent Founding Fathers who were members of societies for ending slavery included Richard Bassett, James Madison, James Monroe, Bushrod Washington, Charles Carroll, William Few, John Marshall, Richard Stockton, Zephaniah Swift, and many more.
In fact, based in part on the efforts of these Founders, Pennsylvania and Massachusetts abolished slavery in 1780; Connecticut and Rhode Island did so in 1784; New Hampshire in 1792; Vermont in 1793; New York in 1799; and New Jersey in 1804. Furthermore, the reason that the states of Ohio, Indiana, Illinois, Michigan, Wisconsin, and Iowa all prohibited slavery was a federal act authored by Rufus King (signer of the Constitution) and signed into law by President George Washington which prohibited slavery in those territories.
