The elimination of slavery in the United States of America has been a lengthy and less than perfect process, beginning with early abolition efforts which occurred during the nation’s colonial period, and which were designed to reduce and ultimately end the buying, selling, and exchanging or bartering of human beings. According to the Pennsylvania Historical and Museum Commission, “the first written protest in England’s American colonies came from Germantown Friends in 1688” in Pennsylvania; the Philadelphia Yearly Meeting of Friends also subsequently “criticized the importation of slaves in 1696, objected to slave trading in 1754, and in 1775 determined to disown members who would not free their slaves.”
That same year, America’s first abolition organization, the Society for the Relief of Free Negroes Unlawfully Held in Bondage, was also established. Formed in Philadelphia on April 14, 1775, the organization became more commonly known as the Pennsylvania Abolition Society. “Throughout the 1700s,” according to PHMC historians, the Pennsylvania Assembly also actively “attempted to discourage the slave trade by taxing it repeatedly,” and then began taking a slightly more intense approach by passing “An Act for the Gradual Abolition of Slavery” by a vote of 34 to 21 on March 1, 1870. The first legislative action of its kind in America, it decreed, among other things, “that ‘every Negro and Mulatto child born within the State after the passing of the Act (1780) would be free upon reaching age twenty-eight,'” and that after their release from slavery, these freed people “were to receive the same freedom dues and other privileges ‘such as tools of their trade,’ as servants bound by indenture for four years.” Heavily opposed by German Lutherans and the representatives of counties with large populations of residents of German heritage, this new law still allowed residents of the Keystone State to continue to buy slaves who had already been registered, but prohibited Pennsylvanians from importing new slaves into the state.
* Note: Although a significant number of German Lutherans initially opposed the state’s 1870 abolition act, many German Methodists adopted anti-slavery positions, as did many who were considered to be “Forty-Eighters” (Germans who emigrated to America during or after the revolutions of 1848).
Although opponents of Pennsylvania’s new abolition law continued to challenge this legislation for several years after its passage, the legislation ultimately survived, and was subsequently strengthened in 1788 to stop Pennsylvanians residing near the borders of Delaware and Maryland from sneaking slaves into the state in violation of the law. The full wording of Pennsylvania’s initial abolition act read as follows:
When we contemplate our Abhorence of that Condition to which the Arms and Tyranny of Great Britain were exerted to reduce us, when we look back on the Variety of Dangers to which we have been exposed, and how miraculously our Wants in many Instances have been supplied and our Deliverances wrought, when even Hope and human fortitude have become unequal to the Conflict; we are unavoidably led to a serious and grateful Sense of the manifold Blessings which we have undeservedly received from the hand of that Being from whom every good and perfect Gift cometh. Impressed with these Ideas we conceive that it is our duty, and we rejoice that it is in our Power, to extend a Portion of that freedom to others, which hath been extended to us; and a Release from that State of Thraldom, to which we ourselves were tyrannically doomed, and from which we have now every Prospect of being delivered. It is not for us to enquire, why, in the Creation of Mankind, the Inhabitants of the several parts of the Earth, were distinguished by a difference in Feature or Complexion. It is sufficient to know that all are the Work of an Almighty Hand, We find in the distribution of the human Species, that the most fertile, as well as the most barren parts of the Earth are inhabited by Men of Complexions different from ours and from each other, from whence we may reasonably as well as religiously infer, that he, who placed them in their various Situations, hath extended equally his Care and Protection to all, and that it becometh not us to counteract his Mercies.
We esteem a peculiar Blessing granted to us, that we are enabled this Day to add one more Step to universal Civilization by removing as much as possible the Sorrows of those, who have lived in undeserved Bondage, and from which by the assumed Authority of the Kings of Britain, no effectual legal Relief could be obtained. Weaned by a long Course of Experience from those narrow Prejudices and Partialities we had imbibed, we find our Hearts enlarged with Kindness and Benevolence towards Men of all Conditions and Nations; and we conceive ourselves at this particular Period extraordinarily called upon by the Blessings which we have received, to manifest the Sincerity of our Profession and to give a substantial Proof of our Gratitude.
And whereas, the Condition of those Persons who have heretofore been denominated Negroe and Mulatto Slaves, has been attended with Circumstances which not only deprived them of the common Blessings that they were by Nature entitled to, but has cast them into the deepest Afflictions by an unnatural Separation and Sale of Husband and Wife from each other, and from their Children; an Injury the greatness of which can only be conceived, by supposing that we were in the same unhappy Case. In Justice therefore to Persons so unhappily circumstanced and who, having no Prospect before them whereon they may rest their Sorrows and their hopes have no reasonable Inducement to render that Service to Society, which they otherwise might; and also ingrateful Commemoration of our own happy Deliverance, from that State of unconditional Submission, to which we were doomed by the Tyranny of Britain.

Other states then followed Pennsylvania’s lead, expanding upon it by enacting less conservative measures. During a series of judicial reviews which were conducted in Massachusetts between 1781 and 1783, for example, state leaders there declared that slavery was incompatible with their state’s new constitution.
These various laws, while not perfect, did gradually achieve their aim of reducing slavery in northern states, as did 1807 legislation by the U.S. Congress which made it a crime for Americans to engage in international slave trade (effective January 1, 1808), and which ultimately reduced shipments of slaves from Africa to the United States by ninety percent. With respect to Pennsylvania, specifically, “the number of slaves dropped from 3,737 to 1,706” between 1790 and 1800, according to PHMC historians, “and by 1810 to 795. In 1840, there still were 64 slaves in the state, but by 1850 there were none.”
Meanwhile, Quakers and others active in abolition movements in Delaware, Maryland, and Virginia achieved some success by pressuring slaveholders to agree to free slaves via wills and other methods of manumission so that, by 1860, more than ninety percent of black men, women, and children in Delaware and nearly fifty percent in Maryland were free.
Despite these efforts, however, the ugliness of slavery continued to persist — a fact made all too clear in newspapers and other publications of the period, including via William Lloyd Garrison’s abolitionist newspaper, The Liberator. But it was, perhaps, the nation’s fugitive slave laws which finally made plain slavery’s seemingly unshakeable grip on the country. Passed by the U.S. Congress, the Fugitive Slave Act of 1850 required that all escaped slaves, regardless of where they were captured, be returned to their masters — even if those escaped slaves had made it to safety via the Underground Railroad or other methods and had been given sanctuary by abolitionists in states where slaves had been permanently freed. In response, two years later, Harriet Beecher Stowe released her landmark, anti-slavery novel, Uncle Tom’s Cabin.
After the U.S. Congress set the stage to reverse decades of anti-slavery progress with its passage of the Kansas-Nebraska Act in 1854, abolitionists and other opponents of slavery banded together to form the Republican Party, which held its first national convention in Pittsburgh, Pennsylvania on February 22, 1856. Initially proposing a system which would contain slavery until each individual state where the practice still existed could be forced to eradicate it, the Republican Party adopted a harder, anti-slavery line in 1860 after the election of Abraham Lincoln as President of the United States.
Following the secession of multiple states from the Union, beginning with South Carolina on December 20, 1860, and the subsequent fall of Fort Sumter to Confederate States Army troops in mid-April 1861, the United States descended into a state of civil war with its federal government issuing a call for regular and volunteer troops to preserve the Union. On September 22, 1862, Lincoln formally added the abolition of slavery as one of the federal government’s stated war goals with his release of the preliminary version of his Emancipation Proclamation, which decared that, effective January 1, 1863, “all persons held as slaves within any State, or designated part of a State, the people whereof shall then be in rebellion against the United States shall be then, thenceforward, and forever free.”
But it would take more than two years for that hoped-for dream to truly begin and nearly 150 years for it to be completely embraced by a divided nation.

December 11, 1865: Oregon ratifies the 13th Amendment to the U.S. Constitution.
December 15, 1865: California ratifies the 13th Amendment to the U.S. Constitution.

William H. Seward, Secretary of State of the United States,
To all to whom these presents may come, greeting:
Dec. 18, 1865, Preamble: Know ye, that whereas the congress of the United States on the 1st of February last passed a resolution which is in the words following, namely:
“A resolution submitting to the legislatures of the several states a proposition to amend the Constitution of the United States.”
“Resolved by the Senate and House of the United States of America in Congress assembled, (two thirds of both houses occurring,) That the following article be proposed to the legislatures of the several states as an amendment to the Constitution of the United States, which, when ratified by three fourths of said legislatures, shall be valid, to all intents and purposes, as a part of the said constitution, namely:
“Section 1. Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.
“Section 2. Congress shall have power to enforce this article by appropriate legislation.”
And whereas it appears from official documents on file in this department that the amendment to the Constitution of the United States proposed, as aforesaid, has been ratified by the legislatures of the State of Illinois, Rhode Island, Michigan, Maryland, New York, West Virginia, Maine, Kansas, Massachusetts, Pennsylvania, Virginia, Ohio, Missouri, Nevada, Indiana, Louisiana, Minnesota, Wisconsin, Vermont, Tennessee, Arkansas, Connecticut, New Hampshire, South Carolina, Alabama, North Carolina, and Georgia; in all twenty-seven states;
And whereas the whole number of states in the United States is thirty-six; and whereas the before specially-named states, whose legislatures have ratified the said proposed amendment, constitute three fourths of the whole number of states in the United States;
Now, therefore, be it known, that I, WILLIAM H. SEWARD, Secretary of State of the United States, by virtue and in pursuance of the second section of the act of congress, approved the twentieth of April, eighteen hundred and eighteen, entitled “An act to provide for the publication of the laws of the United States and for other purposes,” do hereby certify that the amendment aforesaid has become valid, to all intents and purposes, as a part of the Constitution of the United States.
In testimony whereof, I have hereunto set my hand, and caused the seal of the Department of State to be affixed.
Done at the city of Washington, this eighteenth day of December, in the year of our Lord one thousand eight hundred and sixty-five, and of the Independence of the United States of America the ninetieth.
WILLIAM H. SEWARD.
Secretary of State.
December 28, 1865: Florida ratifies the 13th Amendment to the U.S. Constitution.
January 15, 1866: Iowa becomes the 31st state to approve the 13th Amendment to the U.S. Constitution (alternate date January 17, 1866).

February 7, 2013: Mississippi becomes the final state to achieve certified ratification of the 13th Amendment to the U.S. Constitution.
* Note: According to 2013 news reports by staff at ABC and CBS News, although Mississippi legislators finally voted for ratification of the 13th Amendment in 1995, they never notified the U.S. Archivist. As a result, their effort to formally abolish slavery was still not official – an error which was discovered in 2012 by Ranjan Batra, an immigrant from India and professor of Neurobiology and Anatomical sciences at the University of Mississippi Medical Center. After enlisting the help of a medical center colleague (long-time Mississippi resident Ken Sullivan) in uncovering documentation of the oversight, Batra then alerted Mississippi’s Secretary of State Delbert Hosemann, who finally rectified the error by sending the U.S. Office of the Federal Register a copy of Mississippi’s 1995 resolution on January 30, 2013. When that resolution was published in the Federal Register on February 7, 2013, Mississippi’s abolition of slavery finally became official.
