History isn't a neat line. If you're looking for a single calendar date to mark when did slavery start and end, you're going to be disappointed because human cruelty doesn't usually follow a schedule. It's messy. It’s a series of overlapping tragedies that spans thousands of years and every single continent. Honestly, the idea that slavery began in 1619 is a massive misconception that ignores about 5,000 years of prior global history, though that specific date is obviously a turning point for what would become the United States.
Slavery is old. Really old.
We’re talking about a practice that predates the invention of money and, in some regions, even the invention of writing itself. It evolved from a byproduct of war into a massive, industrialized engine of global wealth. Then, it slowly—painfully slowly—began to be outlawed, though the "end" is a word we have to use very carefully.
The Murky Beginnings: It’s Older Than You Think
When people ask about the start of it all, they often look for a specific king or a specific year. You won't find one. Archaeologists and historians like Orlando Patterson, who wrote Slavery and Social Death, argue that slavery emerged as an alternative to execution. Basically, if you lost a war in the Neolithic period, the winners either killed you or kept you to do the heavy lifting.
The Code of Hammurabi, which dates back to about 1754 BCE in Mesopotamia, already has detailed laws about slavery. This proves it wasn't a new idea even then. It was a baked-in part of society. In Ancient Egypt, the building of the pyramids—contrary to popular Hollywood tropes—was largely done by paid laborers, but slavery definitely existed in the wider Egyptian economy, especially for domestic work and mining.

Ancient Greece and Rome took it to a whole different level.
In Rome, slavery wasn't about race. It was about power. If you were on the wrong side of a Roman legion, you ended up in a galley or a field. By some estimates, nearly 30% to 40% of the population in Italy during the first century BCE was enslaved. That is a staggering number. It was the backbone of the entire Mediterranean economy.
The Shift to the Atlantic Trade
The conversation about when did slavery start and end usually shifts gears when we hit the 15th century. This is when the "Old World" style of slavery—which was often (though not always) temporary or non-hereditary—mutilated into the Transatlantic Slave Trade.
The Portuguese started it.
In the 1440s, Portuguese explorers began kidnapping people from the coast of Western Africa. By the time Columbus bumped into the Americas in 1492, the machinery was already in motion. What changed here was the scale and the justification. It became "chattel slavery." This meant the person wasn't just a servant for a term; they were legal property, like a cow or a hammer. And their children were property, too.
Then came 1619.
In August of that year, a privateer ship called the White Lion landed at Point Comfort in the Virginia colony. They had "20 and odd" Africans on board who had been seized from a Portuguese slave ship. This is often cited as the start of slavery in what would become the U.S., but Spanish explorers had actually brought enslaved people to Florida decades earlier. It's a reminder that history is often told through a very narrow, English-speaking lens.
The Long, Bloody Road to Abolition
Ending it wasn't a single "Aha!" moment of moral clarity. It was a grind. It involved massive slave revolts, economic shifts, and relentless pressure from activists.
The Haitian Revolution (1791–1804) is arguably the most important event in this timeline. Enslaved people rose up and defeated the French Empire, creating the first free black republic. It terrified slaveholders everywhere. It proved the system wasn't invincible.
In the UK, the Slavery Abolition Act of 1833 technically "ended" slavery in most of the British Empire, but there was a catch. They forced the formerly enslaved people into "apprenticeships" that were basically slavery by another name. Even more shocking? The British government took out a massive loan to pay reparations—not to the slaves, but to the owners for their "lost property." That loan wasn't fully paid off until 2015.
In the United States, the timeline is marked by the 13th Amendment in 1865.
But you've got to look at the fine print. The 13th Amendment abolished slavery "except as a punishment for crime." This loophole was exploited almost immediately through "Black Codes" and convict leasing. If you were a Black man in the South in 1870 and you were arrested for "vagrancy" (basically being unemployed), you could be leased out to a coal mine or a plantation. It was slavery under a different legal heading.
When Did It Actually "End" Globally?
If you’re looking for the last country to officially abolish slavery, the answer is Mauritania. They didn't pass a law making it illegal until 1981. Even then, they didn't make it a crime you could actually be prosecuted for until 2007.
That’s wild. 2007.

But here is the hard truth: slavery hasn't ended. According to the Global Slavery Index and the International Labour Organization (ILO), there are more people in "modern slavery" today than at the height of the Transatlantic Slave Trade. We're talking about roughly 50 million people. This includes forced labor, debt bondage, and forced marriage.
Why the Timeline Still Matters Today
Understanding when did slavery start and end isn't just a trivia exercise. It explains why global wealth looks the way it does. The sugar, cotton, and tobacco industries built the modern financial world. Many of the world’s oldest banks and insurance companies, like Lloyd’s of London, have roots in the slave trade.
When you look at the timeline, you see that the period of "freedom" in many places is much shorter than the period of enslavement. In the U.S., slavery lasted for 246 years. The Jim Crow era lasted another 100. We are only a few decades into a world where legal equality is even a stated goal.
Real-World Action Steps
History is heavy, but it's not just something to read about. You can actually do something with this information.
- Audit your consumption. Use tools like the Slavery Footprint website to see how many forced laborers likely contributed to the clothes you’re wearing or the phone you’re holding.
- Support modern-day abolitionists. Organizations like Free the Slaves or International Justice Mission (IJM) work on the ground to liberate people from debt bondage and human trafficking.
- Trace the local history. If you live in an older city, look into the historical records of your local businesses and universities. Many are only now beginning to acknowledge how they were funded by the slave trade.
- Read first-hand accounts. Move beyond the dates. Read The Interesting Narrative of the Life of Olaudah Equiano or Frederick Douglass’s autobiography. The dates give you the skeleton, but these narratives give you the reality.
The "end" of slavery is a work in progress. It’s a legal reality in most places, but an economic reality in far too many. Knowing the timeline is just the first step in making sure the "end" actually happens for everyone.
