When you look at the grainy black-and-white photos of white hoods and burning crosses, it feels like a movie. Or a distant nightmare. But for thousands of families across the American South and beyond, that imagery wasn't some abstract symbol of hate. It was a physical threat that ended in blood. Honestly, trying to pin down exactly what the KKK did to people is a heavy task because their "tactics" weren't just about physical pain—they were about psychological obliteration.
They wanted people to live in a state of constant, vibrating fear.
It started in Pulaski, Tennessee, right after the Civil War. A bunch of Confederate veterans decided to start a social club. Sounds harmless, right? It wasn't. It quickly morphed into a paramilitary force designed to undo everything the Reconstruction era was trying to build. They didn't just disagree with the new laws; they used murder to rewrite them.
The Night Riders and the Art of Intimidation
The most iconic, and terrifying, thing the Klan did was "night riding." Imagine sitting in your home at night, the only light coming from a kerosene lamp, and suddenly hearing the thunder of dozens of horses. You look out the window and see men draped in white sheets, pretending to be the ghosts of Confederate dead. They’d ride up to the homes of Black families or white Republicans and issue "warnings."
Sometimes a warning was just a note. Other times, it was a brutal whipping. They targeted anyone who was "getting ahead." If a Black man bought his own land, he was a target. If he tried to vote, he was a target. If he didn't tip his hat fast enough to a white person on the street, he was a target.
The violence was incredibly specific. They didn't just want to kill; they wanted to make an example. In 1871, a federal grand jury report described the Klan’s activities in South Carolina, detailing how they dragged men from their beds in the middle of the night, took them into the woods, and whipped them until their backs were "a mass of raw flesh." This wasn't a rare occurrence. It was a weekly routine in many counties.

Economic Sabotage and Social Exile
We often talk about the lynchings—and we should, because they were horrific—but we forget the "quiet" ways the Klan destroyed lives. They used economic terrorism.
If you were a white shopkeeper who dared to treat Black customers with dignity, the Klan would make sure no one shopped at your store. They’d burn your crops. They’d kill your livestock. Basically, they’d make it impossible for you to survive in the community. For Black sharecroppers, the stakes were even higher. If a worker complained about being cheated on their wages, the Klan might show up at their cabin that night to "discipline" them.
They effectively created a shadow government. In many towns, the sheriff, the judge, and the local businessmen were all under those hoods. This meant that if the Klan did something to you, there was no one to call. The person who was supposed to take the police report was likely the same guy who held the torch at your front door.
The Horror of the 1920s Rebirth
Most people think the Klan died out after the 1870s. It did, for a bit. But it came roaring back in 1915, thanks in part to the movie The Birth of a Nation. This "Second Klan" was even more organized. They didn't just hate Black people; they went after Catholics, Jews, and immigrants.
What did the KKK do to people during this era? They turned hate into a business model. They had millions of members. They marched down Pennsylvania Avenue in Washington D.C. with their faces uncovered. They used their massive numbers to take over state legislatures in places like Indiana and Oregon.

During this time, the violence became more "public." This was the era of the spectacle lynching. Thousands of people—men, women, and children—would gather to watch a human being be tortured and murdered. They would take "souvenirs" like pieces of clothing or even body parts. It’s hard to wrap your head around that level of depravity, but it’s the historical truth. These weren't just fringe outcasts; these were "respectable" members of society participating in ritualized murder.
The Attack on the Family Unit
One of the most devastating things the Klan did was target the family structure. By killing the breadwinner or the patriarch of a family, they didn't just end one life; they doomed the survivors to poverty and trauma.
- Kidnappings: Dragging parents away in front of their children to "teach them a lesson."
- Sexual Assault: Often overlooked in history books, the KKK frequently used sexual violence against Black women as a tool of terror and subjugation.
- Arson: Burning down homes and churches, which were the only safe spaces these communities had.
When you burn a church, you aren't just destroying a building. You're destroying the heart of a community’s social and political life. The Klan knew this. That’s why the 16th Street Baptist Church bombing in 1963 was so calculated. They killed four little girls—Addie Mae Collins, Cynthia Wesley, Carole Robertson, and Carol Denise McNair—because they wanted to break the spirit of the Civil Rights Movement.
The Psychological Toll: Living Under the Hood
The constant threat changed how people walked, talked, and breathed. If you lived in a "Klan town," you lived in a state of hyper-vigilance. You taught your children to be invisible. You learned which roads were safe and which ones would get you killed after dark.
Dr. W.E.B. Du Bois and other contemporary scholars noted that this environment created a "double consciousness." You had to see yourself through the eyes of a hostile world just to stay alive. The KKK didn't just hurt people's bodies; they tried to colonize their minds with fear. They wanted Black people to believe they were subhuman and that their lives didn't matter.

Why This History Still Stings
Understanding what the KKK did to people is crucial because the "tactics" didn't just disappear. They evolved. The way they used misinformation, intimidation at polling places, and the co-opting of local law enforcement provides a blueprint for how extremist groups operate even today.
It’s not just about "hate." It’s about power. The Klan used violence to maintain a racial hierarchy that benefited them economically and socially. When someone asks what the KKK did, the answer is simple but expansive: they used every tool of cruelty available to ensure that a specific group of people could never feel truly at home in their own country.
Moving Forward with Knowledge
To truly understand the impact, you have to look at the stories of survivors. Organizations like the Equal Justice Initiative (EJI) have done incredible work documenting thousands of lynchings that were previously ignored by history books. Their "Legacy Museum" in Montgomery, Alabama, provides a visceral look at the physical and emotional wreckage left behind by the Klan and its offshoots.
If you want to take an active step in honoring the victims and ensuring this history isn't erased, consider the following:
- Support Local History Projects: Many Southern towns are finally starting to place markers at the sites of lynchings and Klan violence. These projects often need local support to overcome political resistance.
- Educate on Reconstruction: Most school curriculums gloss over the years between 1865 and 1877. Read Eric Foner’s work on Reconstruction to see how the Klan’s violence was a deliberate political tool used to overthrow democratically elected governments.
- Monitor Modern Extremism: Groups like the Southern Poverty Law Center (SPLC) and the Anti-Defamation League (ADL) keep tabs on the remnants of the Klan and similar white supremacist organizations. Staying informed about their current tactics is the best way to prevent history from repeating itself in a new disguise.
The KKK’s legacy is a scar on the American landscape, but you can’t heal a wound you refuse to look at. By acknowledging the sheer scale of the terror they inflicted, we can better understand the systemic issues that still plague the country and work toward a version of justice that the victims of the "Night Riders" never got to see.
