By the time the slave trade was abolished in the United States in 1808, the wheels of progress had already been in motion for decades.

The Effects of the Slave Trade on West Africa
The Transatlantic Slave Trade had a devastating effect on West African communities. Approximately 12 million Africans were enslaved and taken to the Americas, leading to the erasure of cultures and the impoverishment of the region--slave traders targeted the healthy young men and women who were vital to the growth and economic health of their communities.
The slave trade represented 95% of the region’s export revenue
To secure a constant supply of slaves, Europeans would also agitate and incite local conflicts between tribes. Slave traders could then officially purchase prisoners of war from whichever side won. This era of manufactured conflict, in addition to the introduction of powerful new weaponry, broke down social ties between communities, destabilized local economies, and decimated agriculture throughout western Africa.

5 Reasons Why Slavery Was Abolished
There were several reasons why America abolished the slave trade in 1807. Among these were:
A growing interest among the general public in the moral and human rights implications of the slave trade
Abolitionist activism, first led by American Quakers, and later by British Quakers in the Society for Effecting the Abolition of the Slave Trade
International influence from Great Britain, which had colonized much of America, and had an impact on American laws and culture
The American Revolution and The Declaration of Independence, which laid the groundwork for an equal and democratic society
The domestic slave population in the United States was large and self-sustaining, meaning that southern states could still profit off of the sale of slaves on federal soil, and that their cotton-based economy could still function as it had previously
Factors that Led to the Abolition of the Slave Trade
Let's take a deeper look at the factors that played a role in the abolition of the slave trade.
Factors that Led to The Abolition of the Slave Trade: The Case of James Somerset
In 1769, an American named Charles Stewart brought the enslaved James Somerset to England. While there, Somerset escaped, and then demanded his freedom. Here is a quick overview of the case, Stewart v Somerset (1771):
- By the time Stewart apprehended him, Somerset had received a Christian baptism.
- Somerset's new godparents, English citizens, came to his legal aid, claiming that Stewart had no right to imprison him as a slave.
- Somerset’s lawyers argued that there was no law that authorized slavery in England.
- Stewart’s lawyers argued that property rights must be protected and prioritized.
- The judge agreed with Somerset, who then secured emancipation.
The trial wasn’t just decisive for Somerset, it was a turning point for Great Britain. Though the decision didn’t legally abolish the slave trade, the trial had brought the question of abolition to the forefront of the British public’s mind and resolved that it was inconsistent with their values. It also had a major impact on the abolitionist movement in America. Activists saw this decision as strengthening the legal basis for their cause, and legislators understood it to pose a threat to the American slave trade.
This gave concern to American slave owners who feared, because the United States had not yet won independence from Great Britain, that an anti-slavery sentiment in London could have consequences throughout its colonies.
Factors that Led to the Abolition of the Slave Trade: The Society for Effecting the Abolition of the Slave Trade
Many of the seeds of abolition were planted by Quaker communities in the American colonies and Great Britain.
Quaker:
a member of the Protestant Christian movement, The Religious Society of Friends, that believed in nonviolence, pacifism, and a direct connection to God which precludes the need for a formal ministry
The first documented protest of enslavement within the colonies was the Germantown Quaker Petition Against Slavery in 1688. This petition was written in the colony of Pennsylvania, in a community founded by German settlers. In Germany’s culture only criminals were used as slaves. To them, the practice of owning slaves was barbaric and contradictory to the ideals of freedom the new world espoused.
It would be almost a century later, in 1780, that Pennsylvania would pass the Abolition Act. This act sought to gradually emancipate the state’s enslaved population. It was only fully accomplished in 1847, when the final slave was freed.
In 1787, London saw the formation of The Society for Effecting the Abolition of the Slave Trade. Of the 12 founding members, nine were Quakers. Together, they lobbied for abolition to be enacted throughout the British Empire and in West Africa. Through years of publications, national speaking tours, and activism, they were instrumental in British parliament’s passing of the Act for the Abolition of the Slave Trade in 1807.
Factors that Led to the Abolition of the Slave Trade: The American Revolution
The American Revolutionary War (1775-1783) won the United States its independence from Great Britain, and in the process created upheaval in the institution of American slavery. Many enslaved Africans in the southern states were able to escape to freedom in the fray of war, while others joined the battle and earned their freedom by fighting with the Patriots.
The anti-slavery movement that had been growing in strength over the previous century found itself fortified in the course of the revolution. Five states had already begun or completed the process of abolition, and other states began to move closer to it.

The Declaration of Independence bolstered the argument against slavery by stating:
all men are created equal...they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.”
It became difficult to legally defend and continue the slave trade in a nation that was founded upon such principles of equality.
