15-Minute History

In the summer of 1184, Emperor Frederick Barbarossa sent his eighteen-year-old son, King Henry VI, to Erfurt to settle a land dispute between Archbishop Conrad of Mainz and Landgrave Ludwig III of Thuringia. The two had been in open conflict since Conrad returned to Mainz the year before, and Henry called a royal assembly in the cathedral provost’s residence to hear them out. Everyone gathered on the upper floor. Nobody seemed too concerned about the open cesspit under the building until the beams gave out. This is the first episode of Weird History, a new monthly segment from 15-Minute History hosted by Dan Lindsay. Each month he’ll bring a story from the stranger side of the past, as long as it actually happened. Join us as we go through what the medieval chroniclers wrote about the collapse, including who died in the pit and how the king and the archbishop got out. We’ll also find out what came of the feud. A room full of the empire’s most powerful men fighting over land on top of a pit of human waste. If…

Our first episode of "Weird History" will be delayed with our apologies!

Last episode was about imperialism, creating multi-ethnic empires that spanned the globe. This is about nationalism, concentrating state power on building and maintaining an ethnic or civic identity. It can lead to greater unity among peoples, but it can also cause world-shattering upheaval! If you want to learn more about Germany's nationalist unification, check out this episode from Season 8--it's a good one!

In September 2026, an AI researcher quit Anthropic and posted a warning that the industry was gambling with our lives. Within days, insiders agreed, and a CEO called for slowing down as a senator pushed a bill to pause advanced AI. Then a second story took off: the whole thing is a psyop, cooked up by AI companies that are losing money and politicians who need an issue to run on. Welcome to the first episode of Conspiracy, a new monthly segment where we lay out the five parts most false conspiracies share: a real hook, a leap, a core that can’t be disproven, a motive with no explanation of how it works, and a messenger people already trust. Then we run the conspiracy through those five parts to determine the probability of the conspiracy. In the end, the goal is freedom in understanding what is real and what is not.

Last week, we covered imperialism through two examples, King Leopold's Congo and India under the British Empire. This week, we discuss the hard questions about imperialism, starting in Berlin, where fourteen powers divided Africa without inviting anyone from the countries being redefined. What do you think? Let us know in your comments.

This season, we're giving the Pop Quizzes a break. Instead, every Thursday we'll have new content from each of our presenters. On the first Thursday of the month, we will be discussing recent political events through a historical lens. Today, Joe and Jon cover the promised $5,000 checks offered by President Donald Trump if his party wins the midterm elections, as well as the historical irony of Germany's traditional parties ignoring a serious political issue and how it is fueling the rise of what many believe to be a radical movement that promises fundamental change in that nation.

Welcome back to a new season of 15-Minute History! Jon, Joe, and the rest of the team are glad to be back for season 10, where we are looking at the forces that made us, both the good and the bad. It was November 15, 1884, and the German chancellor had company. Representatives from fourteen powers arrived at his home in Berlin that day, including Britain, France, Belgium, Portugal, and the United States. Otto von Bismarck had called them together because the governments of Europe all wanted pieces of Africa, their claims were starting to overlap, and he wanted it settled before it turned into another war on the continent. The conference lasted three months. The delegates spent most of that time on trade, on who could use the Congo and Niger rivers, and on what it would take for one country to recognize another's claim to African land. They argued and disagreed. What they did not argue over was who belonged in the room. No African ruler had been invited to Berlin, and none had been consulted beforehand. The…

Was the Treaty of Versailles the cause of World War Two? And what might Germany have looked like without the political chaos that it caused? We hope you've enjoyed these summer pop quizzes. Join us next Monday for the start of Season Ten!!

New Season starting this coming Monday, October 6th! During the break, the 15-Minute History team will be republishing some of your favorite episodes. This episode originally aired on December 9, 2024. --- The benefits of hindsight let us examine faults in national policy through the lens of what followed. But in the midst of a global threat of nuclear war, the United States chose to support vicious dictators in the name of anti-communism. Were they right or wrong? Did it save humanity from death in atomic fire? Was this a good idea or a bad idea?

What rights do citizens of US territories have, and what changes when their homes become states?

New Season starting on Monday, October 6th! During the break, the 15-Minute History team will be republishing some of your favorite episodes. This episode originally aired on May 5, 2025. --- It was still dark. The group of men felt the breeze getting warmer as the eastern horizon began to show signs of light. One of the men, tall with no expression, watched as final preparations were made to a large object in front of the group. The others saw the anxiety in his face in a way that only those had had been around him could discern. The man walked forward, spoke with some of the technicians, and watched them haul it away. It was going to a tower, visible in the distance. Conversations around him continued, but only because it seemed like they had to. Somehow, the silence would have been louder. Not long after, notifications came from the tower; an all clear was given. At 5:29 a.m., a flash of light that was so brilliant it could be seen from 200 miles away blossomed in the desert. The mushroom cloud rose…

Can conservatives promote the "common good" and public virtue using the power of government? This will be our last new pop quiz before the start of Season 10 in a few short weeks. We hope you've enjoyed these quizzes as much as we've enjoyed having these conversations!

During the summer break, the 15-Minute History team will be republishing some of your favorite episodes. This episode originally aired on February 12, 2024. --- As we look at villains in history, we want to look at actions and their effects. The policies of Lyndon Baines Johnson and Ho Chi Minh were the reflection of two leaders operating in different contexts. Though the method by which they exercised their intentions was different, the root of their “why” is in question. Join us as we look at both the intention and result from each leader by examining comparisons of policy during their tenure. The context of culture may require different methods for enacting said policies, but the intentions and subsequent outcomes show the result. We examine those today.

Joe asked a perfectly legitimate question about the definition of prosperity, and within minutes Jon was ranting about other podcasters. The conversation then turned to the national debt's real impact on American life. Fun times!!

During the summer break, the 15-Minute History team will be republishing some of your favorite episodes. This episode originally aired on April 22, 2024. --- "In the chill of a drizzling rain on an October morning, I saw them loaded like cattle or sheep into six hundred and forty-five wagons and started toward the west. One can never forget the sadness and solemnity of that morning. Chief John Ross led in prayer, and when the bugle sounded and the wagons started rolling, many of the children rose to their feet and waved their little hands goodbye to their mountain homes, knowing they were leaving them forever. Many of these helpless people did not have blankets and many of them had been driven from home barefooted." - From the Journal of Private John Burnett, 2nd Regiment. Join us as we teach you about the Trail of Tears, its root causes, and its effects.

During the Gilded Age, companies paid employees in scrip redeemable at corporate stores instead of in hard cash. Is this similar to modern job benefits like health insurance and pensions? Join us every Thursday for new pop quizzes, and stay tuned for the start of our new season in just a few weeks!

During the summer break, the 15-Minute History team will be republishing some of your favorite episodes. This episode originally aired on March 22, 2022. --- Samuel Colt’s name is forever linked to the company he founded and the revolver he called the “Peacemaker.” Born in Connecticut in 1814, he was steeped in America’s gun culture from an early age. His grandfather had served in George Washington’s army, and Samuel inherited an old flintlock pistol from the family hero when he was only six. At the age of fifteen, while working in his father’s textile plant, he built a galvanic cell (basically an early battery) and used it to set off explosives beneath the surface of a nearby pond during the Fourth of July. He continued to experiment with chemicals and combustion—as many young men do—and became fascinated by inventors’ work to create a firearm that could shoot more than bullets before needing to reload. Join us as we teach you about Samuel Colt, Richard Gatling, and John Browning. In this episode, you'll…

What was the Bank of the United States, and why did Andrew Jackson work so hard to destroy it? And why is Eva Braun always referred to as Adolf Hitler's "mistress" even though he was not married? Find out the answer to both questions on this week's pop quiz!

During the summer break, the 15-Minute History team will be republishing some of your favorite episodes. This episode originally aired on October 4, 2021. --- The steamboat passed the port and he looked out at the brown, muddy water. The heat was failing and the humidity began to soak his clothes. Soon it would be twilight and the lighting bugs would begin to flash on the shoreline. As the boat moved downriver, he saw an old wooden raft hitched to a tree near the shore. It had a battered steering rudder, and the logs that were tied together looked so beaten he would have guessed it impossible to serve any function other than kindling. He watched the water move the raft back and forth and smiled to himself, thinking about the hands that made it and what possible experiences someone might have on a craft like that. He turned to the north in the direction they were heading and wondered how a craft like that could get up the river without capsizing. He wondered what would have happened if he had a craft like…

Is America approaching an end similar to Rome's? No. But are there lessons from how the Roman Empire collapsed in the West that nations and leaders can apply to their own situations? Of course, so Joe and Jon explore those topics today. Join us every Thursday this summer for new pop quizzes and on Mondays for rebroadcast episodes!

During the summer break, the 15-Minute History team will be republishing some of your favorite episodes. This episode originally aired on November 14, 2022. --- "I once knew a little boy whose mother and father died when he was six years old. He was a slave and had no one to care for him. He slept on a dirt floor in a hovel, and in cold weather would crawl into a meal bag head foremost and leave his feet in the ashes to keep them warm. Often he would roast an ear of corn and eat it to satisfy his hunger, and many times has he crawled under the barn or stable and secured eggs, which he would roast in the fire and eat. That boy did not wear pants like you do, but a tow linen shirt. Schools were unknown to him, and he learned to spell from an old Webster's spelling-book and to read and write from posters on cellar and barn doors, while boys and men would help him. He would then preach and speak, and soon became well known. He became Presidential Elector, United States Marshal, United States Recorder, United…

Why do people continue to believe the worst about historical villains even if the facts prove they aren't quite as bad as some people thought? Join us every Thursday this summer for new pop quizzes and on Mondays for rebroadcast episodes!

During the summer break, the 15-Minute History team will be republishing some of your favorite episodes. This episode originally aired on October 20, 2025. --- America is often described as a nation of ideas because its founders risked everything for principles in which they believed. But the revolutionaries had to overcome fears in their own hearts and those of their more hesitant countrymen. In this episode, Jon takes us through how America found these ideas, overcame those fears, and clung to hope of victory. Join us for new episodes and discussions every Monday, and comment below with your questions and thoughts, or your own ideas, fears, and hopes. We love hearing from our audience!

Why do politicians always call back to an idea--real or imagined--of the past? Is it as simple as wanting to make their country great again, or is there a deeper motivation? Join us every Thursday this summer for new pop quizzes and on Mondays for rebroadcast episodes!

During the summer break, the 15-Minute History team will be republishing some of your favorite episodes. This episode originally aired on February 9, 2026. --- American progressives at the turn of the 20th century saw major flaws in the United States Constitution and worked to correct them through the process of amendments. Each one was the subject of debate and controversy, and all four made measurable changes to American society (though one can debate the merits of some). Join us for this survey of the four progressive amendments--as well as a funny story from Jon's classroom--and tune in next week for our discussion about how these amendments shaped the future course of American history.

Would Britain have surrendered if Germany had destroyed its army at Dunkirk? This week, Joe and Jon explore one of the classic "what ifs" of the Second World War. Join us every Thursday this summer for new pop quizzes and on Mondays for rebroadcast episodes!

During the summer break, the 15-Minute History team will be republishing some of your favorite episodes. This episode originally aired on December 1, 2025. --- Washington burns. The White House is in flames. But from the smoke and ashes, a nation discovers what it means to be American. The War of 1812's darkest hour became its defining triumph. As British veterans fresh from defeating Napoleon torched the capital, as rockets rained on Fort McHenry, as peace was signed but war raged on, Americans transformed humiliation into legend. Join us for the explosive conclusion of our two-part series on the War of 1812. In this second installment, we witness Perry's amazing victory on Lake Erie, the death of the great Tecumseh, the night America's capital burned to the ground, and Andrew Jackson's stunning victory at New Orleans - a battle that remade American identity, fought two weeks after the war had already ended.

The Europeans may envy America's mighty air conditioners, but what would our country look like without this wondrous invention? Join us every Thursday for new Pop Quizzes this summer!

During the summer break, the 15-Minute History team will be republishing some of your favorite episodes. This episode originally aired on November 17, 2025. --- Detroit falls without a fight. War Hawks demand blood. But on a blood-slick deck, four words become legend: Don’t give up the ship. The War of 1812 is often dismissed as a minor conflict, overshadowed by the Revolution and the Civil War. But this overlooked war forged American identity through fire and defiance on land and sea. Join us as we launch our two-episode exploration of the War of 1812. In this first installment, we experience the gathering storm of grievances - from British impressment and economic strangulation to frontier clashes with Tecumseh's confederacy - that propelled a young nation into battle, the early disasters that followed, and the pivotal moment on Lake Erie when the tide of the war turned.

Jon didn't give his students a reading list this summer, but if he had, what books would he have assigned? Join us every Monday for rebroadcast episodes this summer and on Thursdays for new Pop Quizzes! (Even when they're late--Jon got his dates mixed up because he's a teacher on summer break...)

During the summer break, the 15-Minute History team will be republishing some of your favorite episodes. This episode originally aired on November 3, 2025. --- In the popular mind, John Adams' life and one term as President of the United States is often treated as a footnote alongside the careers of Benjamin Franklin, Thomas Jefferson, and George Washington. But Adams left an indelible mark on his country's history. So as we continue our look into the revolutionary period, this episode shares three elements from his life that capture the essence of this fascinating man.

How do we know when a political party goes "too far" on policy? And what happens when there is a backlash against their ideas? Join us every week this summer for rebroadcast episodes and new pop quizzes!

During the summer break, the 15-Minute History team will be republishing some of your favorite episodes. This episode originally aired on January 26, 2026. --- "You must make your body." An asthmatic boy in wire-rimmed spectacles nods. Decades later, shot in the chest, he'll deliver a 90-minute speech: "It takes more than that to kill a Bull Moose." Theodore Roosevelt is often reduced to caricature - the Rough Rider, the big game hunter, the face on Mount Rushmore. But this oversimplified image misses the man who transformed personal weakness into national strength. Join us as we explore the strenuous life of America's youngest president. We witness the sickly child who willed himself strong, the grieving widower who fled to the Dakota Badlands, the politician who charged up San Juan Hill, and the president who shattered monopolies, protected 230 million acres of wilderness, and built a canal while Congress debated. From a second-floor gymnasium to the White House, Roosevelt proved that privilege demanded…

To celebrate the 250th anniversary of the Declaration of Independence, we've re-recorded an episode from season 1 entitled "Their Safety and Happiness," which looks at the historical and philosophical roots of the document. Joe and Jon then have a new discussion about America's best moments in history, the Declaration's role in our history, and dangerous fun involving fireworks! We hope you all have a happy Independence Day--and that you wake up tomorrow with the same number of fingers and toes!

A political question this week -- what are sanctuary cities and where do they come from? Join us on Mondays this summer for rebroadcast episodes and on Thursdays for new Pop Quizzes. Stay tuned for some additional original content in the coming weeks!

Winston Churchill's insights into the Second World War's outbreak are a fascinating combination of prediction and justification. He knew Germany was a threat, but his postwar memoirs also include knowledge learned during and after the conflict that make it difficult for historians to judge how much he knew as Hitler rose to power. In this episode, Joe asks about how the war could have been prevented and what Churchill knew, and when he knew it. Join us every Thursday this summer for pop quizzes, and on Mondays for rebroadcast episodes!

How did the Central Intelligence Agency both flourish and decline during the Cold War? What effects did both the Suez Crisis and Hungarian Revolution have on the wider world? And how might the world look different in a few years now that the post-Cold War international order is breaking down?

Welcome back to Sketches in History! This segment, just for kids, shows that history isn't just a story; it's an adventure. Join Lottie Archer as she dives into her extraordinary notebook, where sketches from history come to life! In this episode, Lottie finds a torn piece of paper tucked beneath a heavy book on her grandfather's desk: a handwritten note in small, slanted pencil, with no name and no date, just two sentences and a small drawing that looks like a sun, or maybe a star. In this episode, your kids will discover what it looks like when an entire country decides it is done being afraid, why students with a piece of paper and a list of sixteen demands can change the sound of a city street, and what sovereignty really means when you tear a symbol out of your own flag because it was never yours to begin with.

Presidents have always had to balance economic costs with national security. In the 1950s, Dwight Eisenhower took what he called a "new look" at defense policy, which made fundamental changes to how the United States confronted worldwide threats--and had dramatic consequences for allies, enemies, and innocent bystanders. Join us every Monday for episodes and discussions, and on Thursdays for pop quizzes and Sketches in History!

How close has America actually come to falling apart? Not in the way politicians throw the word "crisis" around today, but in real, documented, military-was-deployed, states-were-leaving moments. In this Pop Quiz episode, Jon walks through the moments that nearly broke the republic, what these moments had in common, and the one thread that kept pulling us back from the edge each time. Join us every Thursday for pop quizzes and Sketches in History!

Join us as we discuss the trial of Alger Hiss, why Whittaker Chambers became disillusioned with communism, the Rosenbergs, and the effects of the Red Scare on American society. Join us every Monday for episodes and discussions and on Thursdays for pop quizzes and Sketches in History!

Welcome back to Sketches in History! This segment, just for kids, shows that history isn't just a story; it's an adventure. Join Lottie Archer as she dives into her extraordinary notebook, where sketches from history come to life! In this episode, Lottie finds two things tucked beneath the lamp on her grandfather's desk: a folded newspaper with the headline HISS CONVICTED OF PERJURY and a black-and-white photograph of two men in suits at a table full of microphones, both of them looking like they've been sitting there a very long time. In this episode, your kids will discover what it means to stand up in front of a whole country and say something no one expects to hear, why the question of who is telling the truth can outlast a courtroom verdict, and how the word "testimony" can carry more weight than almost any other word in history.

It is August 3, 1948, and a former Communist Party member named Whittaker Chambers walks into a House committee room in Washington, D.C., and says something that no one in the room ever expected to hear. Alger Hiss is a spy. Hiss was not some offhand bureaucrat. He had helped organize the United Nations and attended Yalta. He had been, for much of the 1940s, one of the most respected foreign policy figures in the American government: Harvard-educated, polished, and credentialed, exactly the kind of man that postwar Washington was built by. The question of who was telling the truth would consume the country for years and leave damage that ran in both directions. Join us every Monday for episodes and discussions and on Thursdays for pop quizzes and Sketches in History!

Why are conspiracy theories everywhere online these days? Why is everyone mad at someone else for every problem in their lives? And what does history teach us about this kind of environment? Join us every Thursday for pop quizzes and Sketches in History!

"We shall not fail now. Let us move forward steadfastly together into the storm and through the storm." - Winston Churchill, February 1942 This Memorial Day, we're republishing our favorite episode where we brought together both parts of our original Storm of War series into one complete telling of the Second World War, with speeches from Churchill, Eisenhower, and others who led through it. From Versailles to Hitler's rise, to the fall of France, to the Battle of Britain. We show you Moscow's frozen gates all the way to Stalingrad. Then, from Normandy to the bunker in Berlin. Here is the full story, on the day we set aside to remember those who didn't return. We honor them by remembering what they faced, what they won, and what it cost. From all of us at 15-Minute History, have a very happy Memorial Day.

Jon didn't remember to publish a pop quiz yesterday--but it was the last day of school and his brain was a bit full. So please accept our apologies and listen to this episode about what historians choose to remember and why!

Our beloved interloper Dan returns to join us for a conversation about the Korean War and how it influenced later conflicts and the role of the military in political affairs. He also shares his thoughts on Lewis "Chesty" Puller and comments on the Marine Corps' role in the American military. You won't want to miss it!

Welcome back to Sketches in History! This segment, just for kids, shows that history isn't just a story, it's an adventure. Join Lottie Archer as she dives into her extraordinary notebook, where sketches from history come to life! In this episode, Lottie finds a dented olive-green tin on her grandfather's desk, cold to the touch, with a folded note tucked underneath in careful pencil handwriting: "We've been looking for the enemy for some time now. We finally found him. We're surrounded. That simplifies things." In this episode, your kids will discover what it means to keep moving when the temperature drops to thirty below, why a calm joke in the middle of a disaster can hold an entire army together, and how the kind of discipline that wins a battle in the Korean mountains is the same discipline you can build in your own life, one decision at a time.

The cold froze rifles in their hands, turned oil to sludge, and stiffened fingers until pulling a trigger became an exercise in willpower. Men slept in shallow foxholes they'd hacked out of frozen ground, ate C-rations turned to ice, and wrapped themselves in as many layers as they could. Decades later, the veterans of America's X Corps recalled the weather more than anything else.
