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 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. ___ Join us as we show you the Manhattan Project, the reason behind the development of nuclear weapons, and the ethical implications of such an invention.

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 that isn’t a metaphor for medieval Europe, we don’t know what is.
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.
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?
