When you think about the people who altered the course of history, it’s easy to imagine the iconic figures—presidents, inventors, and activists whose names fill our history books. But what’s really fascinating is how often the world is transformed by ordinary people who just happened to be in the right place at the right time—or the wrong one.
The thing is, most of these “ordinary” people didn’t set out to be heroes. They weren’t looking to lead revolutions or make headlines. In many cases, they were just reacting to their circumstances or standing up for what they believed in. And yet, their actions had ripple effects that went far beyond what they could’ve imagined. That’s the beauty of history; it’s often shaped by the unexpected.
So, if you’ve ever doubted whether one person can really make a difference, these 14 stories will change your mind.
1. Gavrilo Princip
Gavrilo Princip was just 19 years old when he made a decision that altered the course of the 20th century. He wasn’t a general or a politician, just a young man with strong political beliefs. When he assassinated Archduke Franz Ferdinand in 1914, he set off a chain of events that would lead to World War I.
Princip’s action didn’t just affect Europe—it reshaped the global landscape, leading to the end of empires and the birth of new nations. It’s a stark reminder that one person, in a moment of passion, can change the world, even if they never intended to.
2. Claudette Colvin
Before Rosa Parks made headlines, there was Claudette Colvin. At just 15 years old, Colvin refused to give up her seat to a white passenger on a segregated bus in Montgomery, Alabama, in 1955. She was arrested for her defiance, making her one of the first to challenge segregation laws in this way.
Colvin’s act of bravery didn’t get the attention it deserved at the time, partly because she was a teenager. But her courage helped pave the way for the Montgomery Bus Boycott and the Civil Rights Movement, proving that even young people can make a huge difference.
3. Stanislav Petrov
Stanislav Petrov is probably the reason you’re reading this right now. In 1983, Petrov was a Soviet military officer on duty when the early warning system falsely detected incoming U.S. missiles. Instead of following protocol and launching a retaliatory nuclear strike, Petrov trusted his instincts and reported the alert as a false alarm.
Turns out, he was right. Petrov’s calm decision-making likely prevented a nuclear war, showing that sometimes, changing history is as simple as trusting your gut when it matters most.
4. Oskar Schindler
Oskar Schindler wasn’t a saint. He was a businessman with a sketchy past, but during World War II, something changed in him. As he witnessed the horrors of the Holocaust, Schindler used his factory as a refuge, saving over 1,000 Jewish lives by employing them and protecting them from Nazi persecution.
Schindler didn’t start out with the intention of becoming a hero, but as the war went on, he risked everything—his fortune, his reputation, even his life—to help those in need. His story is a powerful reminder that anyone can choose to do the right thing, no matter where they start.
5. Malala Yousafzai
Malala Yousafzai was just a schoolgirl in Pakistan when she was shot by the Taliban for advocating for girls’ education. But that attack didn’t silence her. In fact, it made her voice even louder. Malala survived the assassination attempt and went on to become the youngest Nobel Peace Prize winner in history.
What’s remarkable about Malala is how she turned a moment of personal tragedy into a global movement. She didn’t set out to change the world—she just wanted an education—but her courage and determination have inspired millions to fight for their rights.
6. Henry Dunant
In 1859, Henry Dunant witnessed the aftermath of a brutal battle in Solferino, Italy. He wasn’t a soldier or a politician, just a businessman. But what he saw changed him forever. Dunant organized care for the wounded soldiers, regardless of their nationality, and this experience inspired him to create the International Red Cross.
Dunant’s work laid the foundation for modern humanitarian aid, proving that even a single act of compassion can lead to global change. His legacy continues to save lives in conflict zones and disaster areas around the world.
7. Harriet Tubman
Harriet Tubman was born into slavery, but she refused to stay there. After escaping to freedom, she risked her life time and time again, returning to the South to lead hundreds of enslaved people to safety through the Underground Railroad.
Tubman’s courage and determination didn’t just free individuals—it helped weaken the institution of slavery itself. She’s tangible evidence that one person’s bravery can be the catalyst for a much larger movement, and her legacy as a freedom fighter remains strong to this day.
8. Maurice Hilleman
Maurice Hilleman isn’t a household name, but his work has saved millions of lives. A microbiologist, Hilleman developed more than 40 vaccines, including those for measles, mumps, and hepatitis. His contributions to medicine are monumental, though he never sought fame or recognition for his work.
Hilleman’s vaccines have prevented countless deaths and made many childhood illnesses a thing of the past. His quiet dedication to science proves that you don’t need to be a celebrity to make a lasting impact on the world.
9. Irena Sendler
Irena Sendler wasn’t a soldier, but she fought her own war during World War II. As a social worker in Nazi-occupied Poland, Sendler helped smuggle 2,500 Jewish children out of the Warsaw Ghetto, hiding them in convents, orphanages, and homes.
Even after being caught and tortured by the Gestapo, Sendler never revealed the identities of the children she saved. Her bravery and compassion in the face of incredible danger saved countless lives, reminding us that sometimes, the greatest heroes are the ones who work in the shadows.
10. Eugene Lazowski
During World War II, Polish doctor Eugene Lazowski found a clever way to save thousands of lives—he created a fake typhus epidemic. By injecting people with a harmless bacteria that caused a positive test for typhus, Lazowski kept the Nazis away from entire communities, sparing them from concentration camps.
His ingenuity saved countless lives and serves as a powerful example of how intelligence and creativity can be just as heroic as bravery on the battlefield.
11. Raoul Wallenberg
Raoul Wallenberg was a Swedish diplomat who risked his life to save tens of thousands of Hungarian Jews during the Holocaust. He issued protective passports and housed people in buildings under Swedish protection, shielding them from the Nazis.
Wallenberg’s efforts weren’t fueled by military might or political power. He used his position as a diplomat to protect the vulnerable, showing that sometimes, standing up to injustice is about finding creative ways to utilize the tools you already have.
12. Alice Paul
Alice Paul wasn’t a household name when she began her fight for women’s suffrage, but her relentless activism helped secure the right to vote for American women. From organizing protests to leading hunger strikes, Paul’s determination pushed the suffrage movement forward, ultimately leading to the passage of the 19th Amendment.
Her story proves that ordinary people, even in the face of massive opposition, can make history. Paul’s bravery and persistence continue to inspire generations of activists.
13. Lech Wałęsa
Lech Wałęsa was an electrician working in the Polish shipyards when he helped lead a labor strike that would eventually bring down the Communist regime in Poland. Wałęsa became the leader of the Solidarity movement, a grassroots effort that demanded workers’ rights and political reforms.
His leadership didn’t just change Poland—it sparked movements across Eastern Europe that contributed to the fall of Communism. Wałęsa’s story is a reminder that even an ordinary worker can rise to the occasion and spark a revolution.
14. Vasili Arkhipov
Vasili Arkhipov quite literally saved the world. During the Cuban Missile Crisis in 1962, Arkhipov was a Soviet naval officer aboard a submarine that came under attack from U.S. forces. His commanders wanted to launch a nuclear torpedo, but Arkhipov refused to authorize it, knowing the consequences could be catastrophic.
His refusal likely averted a nuclear war, showing that certain points in history hinged on a single decision made in a split second. Arkhipov’s calm under pressure saved millions of lives, and his quiet heroism stands as a powerful reminder that peace can come from the unlikeliest of places.
