In 1619, the English privateer White Lion brought 20 enslaved Africans to Jamestown, Virginia, thus introducing the institution of slavery to the Northern Hemisphere. In November of the next year, the Mayflower landed off what is now Massachusetts, with 102 Puritans passengers who established the Plymouth Colony. It seems natural to think that the Puritans, who came to the Americas seeking religious freedom—at least for themselves—would have opposed slavery. Unfortunately, not all of them did.
According to Wendy Warren, author of New England Bound: Slavery and Colonization in Early America, throughout the 17th century, many colonists enslaved both Africans and Native Americans all across New England. Still, many of their neighbors were opposed to slavery. Samuel Sewell, the first justice of the Massachusetts Superior Court, published the first anti-slavery pamphlet, “The Selling of Joseph,” in 1700. Years before, Sewell had been involved in the Salem witch trials and had then publicly recanted his participation. In his pamphlet, Sewell states that it is wrong to be bringing enslaved people to Boston, that slavery is not God’s work.
Perhaps not surprisingly, Sewell’s work had little immediate impact on slavery in Massachusetts. Nevertheless, more citizens of New England embraced abolitionist positions as time went on. Vermont abolished slavery on July 2, 1777, less than a year after the Declaration of Independence had been read to the public in Philadelphia.

Then in 1790, Benjamin Franklin sent a letter to Vice President John Adams, enclosing with it a letter from James Pemberton and a petition from the Pennsylvania Society for Promoting the Abolition of Slavery. The First U.S. Congress was the intended recipient of the letters and the petition, to which the Pennsylvania Society, Philadelphia and New York Yearly Meetings of the Society of Friends (Quakers), and the Pennsylvania Society for Promoting the Abolition of Slavery had been resolutely sending anti-slavery petitions as part of the first unified abolition campaign in American history.

Ben Franklin signed the petition from the Pennsylvania Society on February 3, 1790, which called on Congress to “devise means for removing the Inconsistency from the Character of the American People” and to “promote mercy and justice toward this distressed Race.” Despite the fierce debate that all three petitions generated in the House and the Senate, the issue died in committee.

On December 30, 1799, the Reverend Absalom Jones and other free blacks of Philadelphia petitioned Congress, complaining that under the new fugitive slave law, Southerners were kidnapping free Blacks and selling them into slavery in Southern states. They also stated that they hoped slavery could be done away with, saying, “We do not ask for the immediate emancipation of all…yet humbly desire you may exert every means in your power to undo the heavy burdens, and prepare the way for the oppressed to go free….” However, because the issue of slavery was an integral part of the Constitution, only the portions of the petition that concerned fugitive slaves or the slave trade from the U.S. to foreign places were referred to the committee, where the resolution of referral was amended.
As new states with anti-slavery constitutions entered the union, slave owners in Southern states were both unnerved and enraged. They clearly saw the handwriting on the wall—their livelihoods and their way of life were endangered because the opportunity to expand slavery into neighboring states was being shut down.

In the mid-1800s, anti-slavery petitions came to Congress thick and fast, as this ledger from 1836 shows. On July 13, 1836, the Boston Female Anti-Slavery Society implored the women of Massachusetts as women, wives, mothers, sisters, and daughters to unite in opposing slavery in the nation. The address specifically appealed for the abolition of slavery in the nation’s capital, the District of Columbia.

In 1844, the 28th Congress received a petition from Pennsylvanians, who asked it to abolish slavery and not admit any new states to the union that sanctioned slavery.

The drive to prohibit the spread of slavery continued to build throughout the middle of the 19th century. On March 25, 1851, citizens of New York sent a petition to Congress asking it to prohibit slavery and the slave trade in all U.S. territories. Then in 1859–1861, in a serious blow to the proslavery forces in the South, Kansas voters approved the Wyandot (or Wyandotte) anti-slavery constitution on October 4, 1859.

On March 16, 1862, President Abraham Lincoln made a final attempt to persuade states to gradually abolish slavery. He sent a message to Congress, stating, “I recommend the adoption of a Joint Resolution by your honorable bodies which shall be substantially as follows: ‘Resolved that the United States ought to co-operate with any State which may adopt gradual abolishment of slavery giving to such State pecuniary aid, to be used by such State, in its discretion, to compensate for the inconveniences, public and private, produced by such change of system.’” It proved a futile attempt, however, as Congress did not take up his resolution.

On April 16, 1862, President Abraham Lincoln signed the District of Columbia Compensated Emancipation Act, which abolished slavery in Washington, DC, freed 3,100 people, reimbursed those who had legally owned them up to $300 for each freeperson, and offered to pay the newly freed women and men to emigrate. Senator Henry Wilson of Massachusetts sponsored the legislation. Every April 16, the district commemorates DC Emancipation Day.

Then on January 1, 1863, President Abraham Lincoln issued the Emancipation Proclamation, which pronounced “all persons held as slaves” within the states that had seceded from the Union “are, and henceforward shall be free.”
It is critical to remember that the Emancipation Proclamation was an act of war. Lincoln used it to free the slaves only in the states that were still in active rebellion against the Union. No slaves in Confederate states that Union troops then occupied or in border states were affected by the proclamation. And if the Union didn’t win the Civil War, the proclamation would be, quite obviously, null and void.

Even as he issued the proclamation, Lincoln himself was not entirely sure he had the legal authority to do so, but he felt it was imperative that he take the action because he felt it was critical to winning the war. He further believed that if the people of the United States felt he had acted without adequate authority, they would not reelect him in 1864. But they did send him back to the White House in a landslide decision that fall, a ringing endorsement of his leadership and of their belief in his ability to steer the ship of state to safety.

The 13th Amendment to the Constitution of the United States was the final word in the abolition argument, abolishing slavery for good in the United States. The Senate passed it in April 1864, but then it languished for months in the House of Representatives, until President Lincoln took a personal interest in it and insisted that it be made part of the Republican Party’s platform in the 1864 election. In January 1865, the House of Representatives passed the amendment by a vote of 119–56. On December 6, 1865, it achieved ratification by three-quarters of the states.
