15-Minute History

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 men at the table had already decided that this was their conversation to have, and they were entitled to make whatever decision they wanted.

They went home without a finished map, since most of the borders were worked out in later years by treaty and force. But the terms were set, and over the next thirty years nearly all of Africa came under European rule.

Join us as we show you imperialism, how it worked in King Leopold's Congo and in British India, how the people behind it justified it, and how it still affects the world today.

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?

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?

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 40,000 feet into the air, and the shock wave was felt 100 miles from ground zero. The man who all that morning had worn no expression, would later recall remembering a Hindu scripture in that moment: "Now I am become Death, the destroyer of worlds."

Another man who witnessed the test described the overwhelming impression it left: "A new thing had just been born; a new control; a new understanding of man, which man had acquired over nature." Another observer said, "The lighting effects beggared description. The whole country was lighted by a searing light with the intensity many times that of the midday sun."

Humanity had crossed a threshold.

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.
