History is messy. Honestly, most of what we learn in school feels like a dry list of dates and dead guys in wigs, but that's not what history actually is. It’s a series of "wait, what?" moments that spiraled out of control. When you ask what are some major historical events, you’re usually looking for the big hitters—the wars, the revolutions, the stuff that shows up in documentaries with dramatic orchestral music.
But the real story is often weirder.
Take the Black Death. Around 1347, some flea-infested rats hitched a ride on Genoese trading ships coming from the Black Sea. Within a few years, nearly half of Europe was gone. Just... gone. You’d think that’s just a tragedy, right? Well, it basically destroyed the feudal system. Because there were so few workers left, the survivors could suddenly demand higher wages and better rights. It was the accidental birth of the middle class. History is funny like that; a horrific plague ends up giving peasants enough leverage to eventually buy houses and start businesses.
The Printing Press and the Death of Secrets
Before Johannes Gutenberg got busy with his movable type around 1440, if you wanted a book, someone had to sit down and hand-copy it for months. It was slow. It was expensive. Only the super-rich or the Church had the "truth."
Gutenberg changed the game.
Suddenly, ideas could travel faster than a horse. You’ve got Martin Luther nailing his 95 Theses to a door in 1517, and thanks to the press, his "viral" ideas about reforming the Church spread across Germany in weeks. Without that machine, the Reformation might have just been a local argument. Instead, it tore Europe apart and put the power of reading into the hands of normal people. It’s the direct ancestor of your Twitter feed, for better or worse.

That One Tuesday in October 1929
We talk about the Great Depression like it was a slow fog, but the Wall Street Crash of 1929 was a sudden, violent heart attack for the global economy. On October 24, known as Black Thursday, the market lost 11% of its value at the opening bell. People were literally wandering the streets of New York in a daze.
Why does this count as one of those major historical events we still obsess over? Because it didn't just stay in America. It wrecked Germany's fragile economy, which—honestly—is a huge reason why a certain failed painter was able to convince a desperate nation that he had all the answers. The economic misery of the 30s paved a direct, muddy road to World War II.
The Industrial Revolution: When We Stopped Sleeping
Before the late 1700s, life followed the sun. When it got dark, you stopped. Then came the steam engine and factories. Suddenly, we had "shifts." We had "clocks" that actually mattered.
It started in Britain with textiles. James Watt’s refined steam engine meant factories didn't have to be next to a river anymore. They could be anywhere. This led to massive urbanization—people cramming into cities like London and Manchester. It was miserable. Smog, child labor, and cramped tenements became the new normal. But it also gave us the stuff we take for granted: mass-produced clothes, canned food, and eventually, the very computer or phone you're using to read this.
We traded the fresh air of the farm for the efficiency of the machine. It’s a trade we’re still trying to balance today.
The Day the World Almost Ended (Multiple Times)
The Cold War is technically a "period," but it’s punctuated by events that almost deleted humanity. The Cuban Missile Crisis in October 1962 is the one everyone remembers. For 13 days, the US and the USSR played a game of chicken with nukes.
Vasili Arkhipov is a name you should know. He was a Soviet naval officer on a submarine during the crisis. His sub was being pounded by "signaling" depth charges from US destroyers. The captain thought World War III had already started and wanted to launch a nuclear torpedo. To do it, three officers had to agree. Two said yes. Arkhipov said no.
One guy’s "no" is the reason we aren't all living in a Fallout-style wasteland right now. History isn't just about big movements; it’s about individuals making a choice in a high-pressure room.
The Internet: The Final Frontier?
You can’t talk about what are some major historical events without mentioning the birth of the World Wide Web. Tim Berners-Lee wasn't trying to create a place for cat videos in 1989; he just wanted a better way for scientists to share data at CERN.

It’s hard to explain to people born after 2000 how much this changed. Before the web, if you wanted to know a random fact, you had to find an encyclopedia or go to a library. Now, the sum of human knowledge is in your pocket. It’s the Printing Press on steroids. It has toppled governments during the Arab Spring and created entirely new economies based on "likes" and "clicks."
Shifting Perspectives: What We Miss
Sometimes the biggest events aren't "events" at all. They are slow shifts. The discovery of Penicillin by Alexander Fleming in 1928? That’s a major historical event. Before that, a scratch from a rose bush could literally kill you.
Or consider the 19th Amendment in the US (1920). Half the population finally getting the right to vote wasn't just a political tweak; it was a fundamental rewiring of how society functions. We often focus on the "loud" history—explosions and speeches—but the "quiet" history of medicine and civil rights is what actually keeps us alive and free.
How to Actually Use This Knowledge
History isn't just trivia. It's a map. When you look at what are some major historical events, you start to see patterns. You see that economic crashes lead to political extremism. You see that new communication tech (like the press or the internet) always causes a massive social upheaval before things settle down.

If you want to get deeper into this, don't just read the Wikipedia summary. Look for the "diaries of the nobody." Read what a regular baker wrote during the French Revolution. Watch the footage of the Berlin Wall falling in 1989 and look at the faces of the people, not just the politicians.
To truly grasp these milestones, start by picking one era that confuses you—maybe the Sengoku period in Japan or the Reconstruction era in the US—and find a primary source. History is way more interesting when you stop looking at it as a textbook and start seeing it as a long, chaotic group chat that we’re all still part of.
Keep an eye on the 250th anniversary of the United States coming up in 2026. It’s a huge moment for reflecting on how a single document from 1776 managed to kickstart a global shift toward democracy, even with all its initial flaws. Understanding the past is basically the only way to not be totally surprised by the future.
Actionable Next Steps:
- Visit a Local Archive: Most people think history is in DC or London. Your local town has records of how the Great Depression or WWII actually felt on your street.
- Follow "Primary Source" Accounts: Use social media to find historians who post actual scanned letters and photos from the 1800s. It removes the "AI-generated" feel of modern history.
- Cross-Reference: Next time you hear about a major event, look up what was happening in a different country at the same time. You’ll be shocked at the connections.
