Six Endings of Bonded Labor: An Illustrated History of How Slavery and Serfdom Were Dismantled, Country by Country, Across Two Centuries
Britain & the Empire, 1787–1838 • The First Major Power to End Slavery by Statute
On May 22, 1787, twelve men — nine Quakers and three Anglicans, including Thomas Clarkson and Granville Sharp — met at a London printer's shop and founded the Society for Effecting the Abolition of the Slave Trade. They built the world's first mass political pressure campaign: a logo (Wedgwood's "Am I Not a Man and a Brother?" medallion), a boycott of slave-grown sugar, hundreds of public meetings, and 519 abolition petitions to Parliament in a single year. William Wilberforce introduced abolition bills annually for two decades. The slave trade was abolished in 1807; slavery itself across the British Empire by the Slavery Abolition Act of 1833, which freed approximately 800,000 people on August 1, 1834. The British government compensated slave owners with £20 million — 40% of the Treasury's annual income — and finished paying off the loan only in 2015.
1759–1833 • MP for Hull and Yorkshire, evangelical reformer
Sickly Yorkshire MP and evangelical Anglican who in 1787 took up the abolition cause at the urging of Thomas Clarkson and former slave-trader-turned-clergyman John Newton. Introduced an abolition bill in 1791 that lost 163-88; he reintroduced it nearly every year for sixteen years. Lived to hear, three days before his death in 1833, that Parliament had passed the Slavery Abolition Act ending slavery throughout the empire.
Cambridge essayist who devoted 60 years to abolition. Traveled 35,000 miles by horse collecting evidence and slave-ship artifacts (chains, shackles, branding irons) for parliamentary witnesses.
Formerly enslaved African whose 1789 autobiography "The Interesting Narrative" sold widely and gave Parliament its most influential first-person account of the Middle Passage.
Bestselling poet and one of the campaign's most effective writers. Her 1788 poem "Slavery" became required reading in middle-class households and helped recruit women into abolition.
Jamaican Baptist deacon who led the 1831 Christmas Rebellion. Hanged in Montego Bay May 23, 1832. Now a Jamaican National Hero whose face appears on the J$50 note.
Britain pioneered the modern pressure-campaign template — logo, boycott, mass petitions, parliamentary lobbying — that every later abolition movement reused. Compensating slave-owners (rather than the enslaved) became the political cost of legislative success and a recurring grievance. The pattern: religious/moral coalition + economic disruption (Haiti, slave revolts) + political champion + compensation = legislative victory.
Russian Empire, 1861 • Twenty-Three Million Bound Peasants Made Citizens
Tsar Alexander II inherited an empire humiliated by the Crimean War, in which armies of conscripted serfs had been defeated by the smaller, better-equipped forces of Britain and France. Convinced that "it is better to abolish serfdom from above than wait until it begins to abolish itself from below," he convened drafting commissions and on March 3, 1861 (Old Style: February 19) signed the Emancipation Manifesto. Twenty-three million peasants — roughly 38% of the Russian population — received personal freedom, the right to marry without permission, to own property, and to bring lawsuits. But the land settlement was disastrous: peasants received only a portion of the land they had worked, and were charged "redemption payments" extending until 1906. Alexander, "the Liberator Tsar," was assassinated by a People's Will bomb in 1881. The reform's incompleteness fueled the revolutionary tradition that would topple his dynasty.
1818–1881 • Emperor of All the Russias 1855–1881
The son of Nicholas I, raised by the romantic poet Vasily Zhukovsky. Took the throne during the Crimean defeat and concluded that Russia's industrial and military backwardness had a single root cause: serfdom. After six years of commissions, he issued the 1861 manifesto. Also reformed the judiciary, created the zemstvo (local councils), and reduced military service from 25 to six years. Killed by an anarchist bomb on March 13, 1881 — just hours after signing a constitutional reform that would never take effect.
Liberal civil servant who, with his brother Dmitry, drafted the emancipation. Forced into retirement after 1861 by reactionary backlash; vindicated by history.
Exiled radical whose journal Kolokol ("The Bell"), printed in London, was the era's leading voice for full emancipation. Wrote of 1861: "Long live freedom!"
1878 attempted assassin of St. Petersburg's governor in protest of post-emancipation repression. Acquitted by a jury of peers — an event that radicalized Russia further.
Wrote schools and primers for newly emancipated peasants on his Yasnaya Polyana estate. His later writings on land and labor are unimaginable without 1861's failures.
Russia's emancipation shows the limits of top-down reform: legal freedom without secure landholding produced a peasant question that destabilized the empire for half a century. The same dynamic appeared with U.S. Reconstruction (broken promise of "40 acres and a mule") and Brazilian abolition (no land settlement). Freedom without economic foundation reproduces poverty.
United States, 1862–1865 • Four Million Freed by the Bloodiest War in American History
Unlike Britain's negotiated and Russia's decreed abolitions, the United States ended slavery only after the deadliest war in its history — over 750,000 dead, by recent estimates. President Lincoln, an old Whig who once described emancipation as a "fearful issue," issued the Emancipation Proclamation on January 1, 1863 as a war measure freeing slaves in Confederate territory. The Thirteenth Amendment, ratified December 6, 1865, completed the legal abolition. Approximately 4 million people gained freedom — nearly an eighth of the U.S. population. The promise of "forty acres and a mule" was rapidly withdrawn. By 1877, with the end of Reconstruction, Southern states had built a system of sharecropping, convict-leasing, and disenfranchisement that would substitute for slavery for the next ninety years — until the Civil Rights Movement forced its dismantling.
1809–1865 • 16th President of the United States
A self-educated Illinois lawyer who was elected in 1860 not as an abolitionist but as an opponent of slavery's expansion into Western territories. Confronted by secession and the failure of compromise, Lincoln issued the Emancipation Proclamation on January 1, 1863, redefining the war as a struggle for freedom. He was assassinated by John Wilkes Booth at Ford's Theatre on April 14, 1865 — five days after Robert E. Lee's surrender at Appomattox.
Escaped slave turned orator, abolitionist, and statesman. Pressured Lincoln to enlist Black soldiers and to make emancipation a war aim. Lincoln called him "the most meritorious man" he had ever met.
"Moses" of the Underground Railroad; led 70+ enslaved people to freedom on 13 missions. During the war, she scouted for the Union army and led the Combahee Ferry Raid in 1863 freeing 750 slaves.
Pennsylvania Republican congressman who shepherded the 13th Amendment through the House. Demanded land redistribution — the unfulfilled promise of "forty acres and a mule" — to give substance to freedom.
Itinerant abolitionist and women's rights orator. Met Lincoln at the White House in 1864. Recruited Black troops for the Union army and ministered to freed people in refugee camps.
The U.S. example shows that war was the price of immediate, full emancipation in a society where slavery was deeply economically entrenched. Britain (with slavery in distant colonies) and Russia (with serfdom controlled by the state) could legislate; the U.S. could not. The cost: 750,000 dead. The aftermath: a century of substitute systems that show legal abolition without political follow-through can be effectively reversed.
Brazil, 1850–1888 • The Princess Who Signed Slavery's End in 76 Words
Brazil was the largest destination of the Atlantic slave trade — importing roughly 5 million enslaved Africans, more than four times as many as the United States — and the last major nation in the Americas to end slavery. After British pressure forced the end of the trans-Atlantic trade in 1850, abolition came in piecemeal steps: the Free Womb Law (1871) freed children born to enslaved mothers; the Sexagenarian Law (1885) freed those over 65. Mass desertions, an organized abolitionist movement led by figures like Joaquim Nabuco and André Reböuças, and the disintegrating slave system itself made enforcement impossible. On May 13, 1888, Princess Isabel signed the Lei Áurea (the "Golden Law") — just 76 words declaring slavery extinguished. The law freed approximately 700,000 remaining enslaved people. The slave-owning planter class never forgave the monarchy; one year and six months later, a republican coup deposed Emperor Pedro II and ended Brazilian monarchy forever.
1846–1921 • Princess Imperial of Brazil; thrice Regent
Daughter of Emperor Pedro II. Acted as Regent during her father's absences in Europe. Long an abolitionist, she signed the 1871 Free Womb Law in her father's stead and on May 13, 1888 signed the Lei Áurea. The Catholic Church blessed her as "the Redemptress." Within 18 months, the planter elite supported the November 1889 republican coup that exiled the Imperial family. She died in France in 1921, never returning to Brazil.
Pernambucano writer-diplomat whose 1883 book "O Abolicionismo" framed slavery as the source of Brazilian backwardness. Founded the Brazilian Anti-Slavery Society and corresponded with Frederick Douglass.
Black engineer and abolitionist of mixed-race descent. Designed Brazilian railroads and ports while raising funds for emancipation. Followed the Imperial family into exile after the 1889 coup.
São Paulo lawyer who led the "caifazes" — an interracial underground network smuggling enslaved people from coffee plantations to free Ceará province. Modeled on the U.S. Underground Railroad.
Self-emancipated lawyer who freed over 500 enslaved people through the courts before his 1882 death. The first Black lawyer in São Paulo and the most successful litigator of his abolitionist era.
Brazil shows that slavery can collapse from below: by 1888, mass desertion, soldier defections, and abolitionist underground networks had already made enforcement impossible. The Lei Áurea ratified what was happening de facto. The same pattern appears with Indian indenture (1917) and post-1960s African chattel slavery. Once enforcement breaks, the law catches up.
Northern Nigeria, 1900–1936 • Britain's Reluctant, Gradual African Abolition
When Britain conquered the Sokoto Caliphate in 1903, it acquired what may have been the world's largest remaining slave-owning society — an estimated 2.5 million enslaved people across the emirates of northern Nigeria. Yet the new colonial governor, Frederick Lugard, refused to issue a general emancipation. His "indirect rule" preserved the emirs' authority, the Islamic legal system, and economic relations with slave-owners as the Caliphate had practiced them. Instead, Britain abolished the legal status of slavery in stages: the slave trade in 1901, the legal status of slavery in 1936, and finally the institution itself with the 1936 Anti-Slavery Society of Nigeria's reforms. Some historians estimate that "freed" enslaved people had to purchase their own freedom from masters via a process called "self-redemption" — making this perhaps the slowest abolition in world history.
1858–1945 • High Commissioner for Northern Nigeria 1900–1906
British colonial administrator whose conquest of Northern Nigeria in 1903 absorbed the Sokoto Caliphate. Refused immediate emancipation, fearing economic disruption and resistance from emirs. His 1922 book "The Dual Mandate in British Tropical Africa" justified gradual abolition through colonial law. Critics including Anti-Slavery Society activists charged that his system preserved slavery in all but name for over thirty years after British conquest.
The last independent Caliph of Sokoto, defeated and killed at Burmi in 1903. His resistance — and his Hijra westward — became a touchstone of anti-colonial memory for Nigerian Muslims.
Hausa woman whose 1954 oral autobiography (recorded by anthropologist Mary F. Smith) gave one of the few first-person accounts of life under and after slavery in Northern Nigeria.
Anti-Slavery Society secretary who exposed Lugard's "domestic slavery" toleration in pamphlets from 1909 onward. Helped force colonial policy revisions in 1916 and 1936.
Modern Canadian historian whose "Transformations in Slavery" (1983) and "Slow Death for Slavery" (with Jan S. Hogendorn, 1993) reconstructed the colonial-era slave trade and abolition statistics.
Sokoto's gradual abolition shows the limits of colonial benevolence. A power that had abolished slavery at home (1833) tolerated it in newly conquered territories for fear of disruption. The model spread across French, German, and Portuguese Africa — making colonial-era African abolition the slowest and most incomplete in modern history.
Arabia & West Africa, 1962–2007 • Where Slavery Ended Within Living Memory
Slavery survived legally into the second half of the 20th century in two strongholds: Saudi Arabia and Mauritania. King Faisal of Saudi Arabia abolished slavery by royal decree in 1962, freeing approximately 30,000 enslaved people; Saudi Arabia compensated owners ~US$700 each. Mauritania — where Arab-Berber masters had enslaved sub-Saharan Africans for centuries — abolished slavery in 1981 by decree, but the prohibition was largely unenforced and lacked criminal penalties. It took two further attempts — in 2007 (criminalization) and 2015 (creating special anti-slavery courts) — before any actual prosecutions began. Activists like Biram Dah Abeid, repeatedly imprisoned, estimate that descent-based slavery still affected hundreds of thousands of Mauritanians as recently as 2020. Mauritania remains the country where slavery's modern survival is most documented and most contested.
1906–1975 • King of Saudi Arabia 1964–1975
Faisal abolished slavery in Saudi Arabia by royal decree in November 1962, while serving as Crown Prince and Prime Minister, before formally taking the throne. The decree freed an estimated 30,000 enslaved people, with the government paying compensation of about US$700 per person to former owners. Faisal also abolished public flogging, banned polygamy in his own family, and introduced television and women's education. Assassinated by his nephew Faisal bin Musaid in March 1975.
Mauritanian abolitionist, founder of IRA-Mauritania. Three-time presidential candidate; multiple imprisonments. Nominated for the Nobel Peace Prize.
Formerly enslaved Mauritanian woman whose 1990s testimony in international forums put a human face on descent-based slavery. Now an activist with SOS Esclaves.
Founder of SOS Esclaves (1995), born to formerly enslaved parents. Repeatedly arrested. Awarded the Robert F. Kennedy Human Rights Award in 2009.
Successive UN human rights officers documented Mauritanian slavery from the 1990s onward, creating sustained international pressure that eventually forced criminalization.
Saudi Arabia and Mauritania show that legal abolition can lag two centuries behind major-power emancipations, and that even criminalization does not automatically end practice. The pattern: international pressure (UN, NGOs, journalists), domestic activists (often imprisoned), and gradual legal reform. The 21st-century focus on "modern slavery" extends this lineage to forced migration, debt bondage, and forced marriage worldwide.

Britain ended slavery peacefully but had no enslaved on home soil. The U.S. paid 750,000 lives for legal abolition. Russia's Crimean defeat catalyzed serfdom's end. Where slavery was deeply embedded in domestic political economy, war was the price of immediate, full legal emancipation.
From Brazilian quilombo desertions to Sokoto walk-aways, enslaved people consistently ended slavery faster than the law permitted. Slave revolts (Saint-Domingue 1791, Jamaica 1831) made continuation politically impossible. Liberation was always a partnership of the enslaved with sympathetic outsiders.
Britain paid £20M to slaveowners (loan finished 2015). Russia's redemption payments fell on freed serfs. The U.S. paid no one. Saudi Arabia compensated owners $700 per person. Mauritania compensated no one. In every successful case, compensation went to former owners, not the freed.
"Forty acres and a mule" was withdrawn; Russian land was inadequate; Brazilian freed had no land at all. Each incomplete settlement bred a successor system: sharecropping, redemption-debt peasantry, favelas. Legal emancipation without economic foundation reproduces poverty.
Quakers in Britain, Catholic abolitionists in Brazil, Northern churches in the U.S., the Anti-Slavery Society in colonial Africa, and the SOS Esclaves in Mauritania all relied on religious or civic networks. No major abolition succeeded without organized moral pressure beyond the political class.
The Walk Free Foundation estimates ~50 million people in modern slavery in 2024 — forced labor, debt bondage, forced marriage, sex trafficking. Legal abolition is a global achievement, but enforcement is patchy. The abolitionist project continues.
