William Wilberforce and Abolishing the Slave Trade: How True Christian Values Ended Support of Slavery


Rusty Wright provides an insightful summary of the journey which led William Wilberforce from heathenism to Christ and to leading the fight to abolish the slave trade in Britain.  He clearly shows how true Christian values were key in inspiring Wilberforce’s persistent effort to rid Britain of this shameful scourge, the slave trade. 

Slavery’s Scourge

What do you think of slavery? Are you for it or against it?

I suspect most readers would immediately denounce slavery as a scourge on humanity. But in the eighteenth century, much of western society accepted slavery and the slave trade. It took heroic efforts by dedicated leaders to turn the tide.

William Wilberforce, the famous British parliamentarian, helped lead a grueling but bipartisan twenty-year struggle to outlaw the trading of slaves. His inspiring story has many lessons for today’s leaders.

Abraham Lincoln acknowledged Wilberforce’s significant role in abolition.{1} Nelson Mandela, addressing the British Parliament in 1996 as South Africa’s president, declared, “We have returned to the land of William Wilberforce who dared . . . to demand that the slaves in our country should be freed.”{2}

The task was formidable. Eighteenth-century Britain led the world in slave trading. A pillar of colonial economy, the trade was legal, lucrative, and brutal. In one notorious episode, a ship’s captain threw 132 slaves overboard, claiming illness and water shortage. British law protected the ship’s owners, considering slaves property (like “horses,” ruled one judge).{3}

African tribal chiefs, Arab slave dealers, and European traders rounded up Africans, stuffed them into ships’ holds, and delivered them to colonial auctions for sale and forced servitude. The “Middle Passage” across the Atlantic was especially horrific. Slaves typically lay horizontal, shackled and chained to each other, packed like sardines. The air was stale and the sanitation putrid.

Olaudah Equiano, a freed slave, said the “stench of the hold,” the heat, and the cramped quarters brought sickness and much death. The deceased, Equiano explained, fell “victims to the improvident avarice . . . of their purchasers.” He wrote, “The shrieks of the women, and the groans of the dying, rendered the whole a scene of horror almost inconceivable.” Some slaves, when taken up on deck, jumped overboard, preferring death to their misery.{4}

Enter William Wilberforce, young, silver-tongued, popular, ambitious, seemingly destined for political greatness. Then, a profound change led him on a path that some say cost him the prime ministership, but helped rescue an oppressed people and a nation’s character.

Wilberforce’s “Great Change”

The transatlantic slave trade was filled with horror stories about human inhumanity. John Newton, a former slave trader, told of a shipmate “who threw a child overboard because it moaned at night in its mother’s arms and kept him awake.”{5}

William Wilberforce grew up among Britain’s privileged, far from these horrors. Heir to a fortune, he was a slacker and socialite at Cambridge. Sporting an adept sense of humor, he loved partying and playing cards more than schoolwork. His superior intellect frequently covered for his lax academic habits. His keen mind, delightful wit, and charming personality kept many doors open.{6}

At Cambridge, he befriended William Pitt the Younger, who would become Britain’s youngest Prime Minister. Both were elected to Parliament in their twenties. Wilberforce became Pitt’s bulldog, using his oratorical and relational skills to advance Pitt’s legislative agenda.

From 1784 to 1786, what he later called his “Great Change” would forever reshape his life’s work. It began innocently enough when he invited his friend, Cambridge professor Isaac Milner, to accompany him on a journey to France. Milner was a brilliant scientist who eventually became vice chancellor of Cambridge. (That’s similar to a university president in the U.S.) As they conversed during the trip, Wilberforce was surprised to hear Milner speak favorably of biblical faith. Wilberforce was a skeptic and wanted nothing to do with ardent believers to whom he had been exposed in his youth.

During their travels, Milner and Wilberforce spent long hours discussing faith and the Bible. His doubts receded as Milner answered his objections. Initial intellectual assent to Christian faith morphed into deeper conviction and a personal relationship with God.{7}

Back in England, he reluctantly consulted John Newton, slave trader turned pastor and writer of the well-known hymn, “Amazing Grace.” Newton had been Wilberforce’s minister for a time during his youth, before his spiritual interest waned. Wilberforce wrote that after his meeting with Newton, “My mind was in a calm, tranquil state, more humbled, looking more devoutly up to God.”{8} Newton encouraged Wilberforce that God had raised him up “for the good of the nation.”{9}

In time, Wilberforce grew to consider “the suppression of the slave trade” part of his God-given destiny.{10} At first he thought abolition would come quickly, but he guessed incorrectly, as we will see.

The Battle in Parliament

When William Wilberforce first introduced anti-slave-trade legislation into Parliament, he had high hopes. He quickly learned that opposition would be fierce.

Financial stakeholders howled. Significant elements of British economy relied on slavery. Businesspersons didn’t want to sacrifice profit. Their elected representatives didn’t want to sacrifice votes. Some claimed slavery benefited slaves since it removed them from barbarous Africa. The Royal Family opposed abolition. Even Admiral Lord Nelson, Britain’s great hero, denounced “the damnable doctrine of Wilberforce and his hypocritical allies.”{11}

Wilberforce and the Abolitionists repeatedly introduced legislation. Apathy, hostility and parliamentary chicanery dragged out the battle. Once, his opponents distributed free opera tickets to some abolition supporters for the evening of a crucial vote, which the Abolitionists then lost. Enough supporting members of Parliament were at the opera to have reversed the outcome.{12} Twice West Indian sea captains threatened Wilberforce’s life. His health faltered.{13}

Buoyed by friends and faith, Wilberforce persisted. He believed God viewed all humans as equal,{14}citing Acts 17:26, “[God] has made from one blood every nation of men.” Methodism founder John Wesley encouraged perseverance, writing, “If God is with you, who can be against you? . . . Be not weary in well-doing. Go on . . . till even American slavery, the vilest that ever saw the sun, shall vanish away.”{15} John Newton wrote and testified in Parliament about his experiences as a slave trader, “a business at which my heart now shudders,” he explained.{16}

Finally, in 1807, twenty years after beginning, Wilberforce prevailed. Parliament erupted in cheering as the slave trade abolition bill passed.

Of course, outlawing the British transatlantic slave trade in 1807 did not immediately eradicate the trade. In fact, it continued, practiced illegally for a while by British subjects and for decades among other nations like France, Spain and Portugal. Alas, African tribal chiefs and Arab slave-dealers continued to supply captured Africans for the system.{17}

But outlawing the slave trade proved the impetus for a host of social improvements, including prison reforms, child labor laws, and abolition of slavery itself in 1833, of which Wilberforce learned only a few days before his death.

Wilberforce’s Methods: Lessons for Today

The esteemed historian W.E.H. Lecky ranked the British anti-slavery movement “among the three or four perfectly virtuous pages . . . in the history of nations.”{18} While, of course, Wilberforce and his Abolitionist colleagues were not perfect, their historic effort left many lessons for today. Consider a few that could enhance your own interaction in the workplace, academia, politics, cross-cultural engagement, in your neighborhood or family.

The value of friendships and teamwork. Many of the Abolitionists lived for several years in the same community. They and their families enjoyed one another’s friendship and moral support. This camaraderie provided invaluable encouragement, ideas, and correction.

Bipartisan cooperation was essential to Wilberforce’s success. He set aside differences on certain issues to collaborate for the greater good. Both political liberals and conservatives joined the abolition cause. Quakers mobilized support. Wilberforce partnered with Jeremy Benthama founder of Utilitarianismon abolition and prison reform.{19} Utilitarianism, of course, favors the end justifying the means, hardly a biblical value.{20} Yet the two could work together.

Wilberforce sought to make civil discourse civil. Biographer Kevin Belmonte notes, “After his Great Change Wilberforce was nearly always able to dissent from the opinions of others with tact and kindness. This trait grew gradually within him; it was not instantaneous, nor did he always act as charitably as he might have wished on some occasions. But he kept trying.”{21} He aimed to disagree without being disagreeable.

Wilberforce attempted to establish common ground with his opponents. In his opening speech on abolition before Parliament, he was especially gracious. “I mean not to accuse anyone,” he explained, “but to take the shame upon myself, in common indeed with the whole Parliament of Great Britain, for having suffered this horrid trade to be carried on under their authority. We are all guilty we ought all to plead guilty, and not to exculpate ourselves by throwing the blame on others.”{22}

William Wilberforce was not perfect. He had fears, flaws and foibles like anyone. You likely would not agree with all his political views. But he did possess dedication to principle and to God, close friends of many stripes, a penchant for bipartisan cooperation, and steadfast commitment to right terrible injustice. A fine example for life and work today.

Wilberforce’s Motivation: Lessons for Today

Have you ever been tempted by opposition to abandon a good cause? What motivated William Wilberforce to persevere in pursuing abolition for twenty agonizing years?

After discovering faith, Wilberforce viewed the world through different lenses-biblical lenses. He authored a popular book to explain faith’s implications. Famous parliamentarian Edmund Burke, who found solace in it during his last two days of life, said, “If I live, I shall thank Wilberforce for having sent such a book into the world.”{23}

Wilberforce’s book, Real Christianity,{24} emphasized personal, life-changing faith, not mere nominal assent. He wrote, “God loved the world so much and felt such tender mercy for us that He gave His only Son Jesus Christ for our redemption.”{25} He felt all humans have an innate flawself-centeredness or sin that inhibits true generosity, “clouds our moral vision and blunts our moral sensitivity.”{26} He called selfishness “the mortal disease of all political communities”{27} and humbly admitted his own “need and imperfection.”{28}

Wilberforce believed Jesus suffered “death on the cross . . . for our sake” so those accepting His pardon “should come to Him and . . . have life that lasts forever.”{29} Don’t get the cart before the horse, he warned. Good behavior doesn’t earn God’s acceptance; it should be a result of “our reconciliation with God.”{30} Wilberforce encouraged his reader to “Throw yourself completely . . . on [God’s] undeserved mercy. He is full of love, and He will never reject you.”{31}

Wilberforce aspired to the Golden Rule: “doing to others as we would have them do to us.”{32} He believed the faith was intellectually credible and advocated teaching its supporting evidences,{33} but cautioned that “a lack of faith is in general a disease of the heart more than of the mind.”{34}

Wilberforce asked penetrating questions: “Do we love our enemies? Are we gentle even when we are provoked? Are we ready to forgive and apt to forget injuries? . . . Do we return evil with good . . . ? Can we rejoice in our enemy’s good fortune, or sympathize with their distresses?”{35} Sound convicting? Join the club.

An inscribed tribute to Wilberforce at Westminster Abbey where he is buried commends his efforts, “Which, by the blessing of God, removed from England the guilt of the African slave trade, and prepared the way for the abolition of slavery in every colony of the Empire: . . . he relied, not in vain, on God.”{36}

Wilberforce’s legacy of faith and service persists. What will your legacy be?
