Most people hear the phrase "concentration camp" and their minds immediately jump to the horrors of the 1940s. It makes sense. The scale of the Holocaust was so massive it basically redefined how we talk about state-sponsored cruelty. But if you're looking for the technical answer to when did concentration camps begin, you have to look much further back than Nazi Germany.
History is messy. It's rarely a straight line.
Technically, the "first" instances depend on how you define the term, but most historians point to the late 19th century as the moment the concept really took shape. It wasn't about extermination at first. It was about "concentration"—literally moving large groups of "troublesome" civilians into one spot so they couldn't help guerrilla fighters or rebels. It was a tool of colonial war.
The Spanish "Reconcentrados" in Cuba
If you want a specific date for when the modern idea of a concentration camp started, 1896 is a good place to begin. The Spanish Empire was desperately trying to hold onto Cuba. Valeriano Weyler, a Spanish general, realized he couldn't beat the Cuban rebels if the local peasants kept feeding and hiding them.
His solution? The reconcentración policy.
He forced hundreds of thousands of Cubans into fortified towns. They weren't soldiers. They were families, kids, and old people. The Spanish didn't have a plan to feed them. They didn't have a plan for sanitation. Predictably, people started dying by the thousands. We’re talking about roughly 150,000 to 400,000 deaths from disease and starvation in just a few years. This wasn't a "death camp" in the way we think of Sobibor, but the result was the same. It was mass death caused by intentional, forced relocation.
Weyler earned the nickname "The Butcher." Interestingly, the American press at the time—led by guys like Hearst and Pulitzer—used these camps as a rallying cry to start the Spanish-American War. They called them "death camps" to stir up public anger. It's a bit ironic when you look at what happened next in the Philippines.
The American Version in the Philippines
History likes to repeat itself, often faster than we'd like to admit. Shortly after the U.S. took control of the Philippines from Spain, they ran into their own insurgency. Between 1899 and 1902, American generals like J. Franklin Bell used very similar tactics to Weyler.
In Batangas, Bell ordered the entire population into "zones of protection."
If you were outside the zone, you were considered an enemy. Inside the zone, the conditions were miserable. Cholera and malaria ripped through the crowded camps. It's an uncomfortable part of American history that doesn't get much play in textbooks, but it’s crucial to understanding that concentration camps were a global trend in military thinking at the turn of the century. They were seen as a "necessary" military tactic to drain the pond to catch the fish.
The British and the Boer War
While the Americans were in the Philippines, the British were doing the exact same thing in South Africa. This is actually where the English term "concentration camp" became part of the common vocabulary.
During the Second Boer War (1899–1902), the British were fighting Boers—descendants of Dutch settlers who were incredibly good at hit-and-run tactics. To stop them, Lord Kitchener began a "scorched earth" policy. They burned Boer farms and moved the women and children into camps.
But it wasn't just Boers.
The British also interned over 100,000 Black Africans who had worked on those farms. The mortality rates were staggering. In the Boer camps, about 27,000 people died, mostly children. In the Black African camps, the records were poorly kept, but at least 14,000 to 20,000 people perished.
Emily Hobhouse, a British activist, actually visited these camps. She was horrified. She wrote back to London about the "stunted" children and the "stench of death." Her reports actually forced the British government to change how the camps were run, but by then, the damage was done. The concept of the concentration camp was now firmly established as a "legitimate" (if brutal) way for an empire to handle a rebellion.
Why the Definition Matters
So, when did concentration camps begin? If we're talking about the philosophy of it—isolating a group of people based on who they are rather than what they've done—you could argue it goes back even further.
- The Trail of Tears: The forced relocation of Native Americans in the 1830s involved detention centers that looked a lot like camps.
- Civil War Prisons: Places like Andersonville were essentially mass death traps for soldiers, though they were technically POW camps.
- The Armenian Genocide: Starting in 1915, the Ottoman Empire used transit camps as part of a systematic plan to eliminate the Armenian population.
The shift from "military necessity" to "ideological cleansing" is what happened between 1900 and 1930. The Nazis didn't invent the camp; they just perfected it. They looked at the colonial models of the British and the Spanish, and even the American reservations, and realized they could use those structures for their own twisted racial theories.
Dachau, the first Nazi camp, opened in March 1933. Initially, it was for political prisoners—communists and socialists. It wasn't until later that the system evolved into the massive network of forced labor and extermination we associate with the Holocaust.
The Evolution of the Term
Words change. Today, if you call a detention center a "concentration camp," it sparks a massive political debate. People feel like that term should be reserved only for the Holocaust. But historians like Andrea Pitzer, who wrote One Long Night: A Global History of Concentration Camps, argue that using the term correctly helps us spot the warning signs early.
A concentration camp, by definition, is a place where people are imprisoned not because of a trial or a specific crime, but because of their identity or membership in a group.
When you look at it that way, the timeline is long and ugly. It spans continents. It involves empires that we usually think of as "the good guys." It’s a tool that has been used by almost every major power in the last 150 years to handle "undesirables" or "enemies of the state."
Actionable Insights for the History-Conscious
Understanding the origins of these camps isn't just about trivia. It’s about recognizing patterns. Here is how you can practically apply this historical perspective:

- Differentiate the Types: When reading about history or current events, distinguish between "internment camps" (often civilian detention during war), "labor camps" (exploitation for economic gain), and "extermination camps" (specifically designed for mass murder). They are all concentration camps, but their goals differ.
- Check Primary Sources: If you're researching a specific era, look for the accounts of people like Emily Hobhouse or the "reconcentrados" in Cuba. Official government reports from the time almost always downplay the death tolls and conditions.
- Trace the Influence: Look at how the Nazi regime studied the colonial camps of the 19th century. There is a direct line of "intellectual" theft where one regime learns "best practices" for mass detention from another.
- Identify Modern Parallels: Use the historical definition (mass detention without trial based on group identity) to evaluate modern refugee camps or political detention centers. History shows that even when a camp starts for "safety" or "administrative" reasons, it often descends into a humanitarian crisis due to neglect.
The history of the concentration camp is a history of what happens when a government decides that a specific group of people is no longer entitled to the same rights as everyone else. It started as a desperate military tactic in the jungles of Cuba and the plains of South Africa, but it became one of the darkest legacies of the 20th century.
