Why Did So Many Ancient Civilizations Collapse at the Same Time? 🏺🌍 | The Bronze Age Collapse Explained | Boring History for Sleep

Hey there, night owls. Tonight we are talking about the day the ancient world ended. Around 1200 BC, nearly every great civilization around the Eastern Mediterranean collapsed at once, and we can literally see it in the ground. Dig under those cities, and you find the same thing every time. A lived-in floor, then a band of burnt earth, then nothing. Forty-odd sites, different countries, different gods, same layer of ash. The scoreboard is brutal. The Hittite Empire vanishes. Mycenaean Greece goes dark. Ugarit burns and is never rebuilt. Not once, not ever. Cyprus, Canaan, the whole copper and tin trade switched off inside two generations. Even writing disappears. Greece then spends about four hundred years without leaving us a single document, which is one way to avoid paperwork, I guess. Eight or nine independent kingdoms, all rich, all dying together. So what can kill that many states at the same time? No single villain, no one guy with a torch. Just a chain of disasters that landed on top of each other, and science can finally measure them. Pollen from the Dead Sea, a stalagmite in a Greek cave, DNA from ancient burials, and a CT scan of a pharaoh who did not die peacefully. Hit that like button, dim the lights, and tell me in the comments where you're watching from and what time it is right now. Ready? Let us dig.

Before we can explain how this world died, we need to look at how well it was working, because the size of the loss only makes sense once you see the machine that was humming along right up until the lights went out. And the fastest way to see that machine is not a temple, not a pyramid, and not a king list. It is one small merchant ship that went down off a rocky headland in southern Turkey, and then sat there quietly for about 32 centuries, waiting for someone with an air tank to notice. The headland is called Uluburun, just east of the modern town of Kaş, a place that today is mostly known for turquoise water, and people paying too much for lunch with a seaview.

In the summer of 1982, a local sponge diver named Mehmet Çakır was working the slope below the cape, and came back up talking about strange metal objects on the seabed. He described them as metal biscuits with ears, which is, if you have ever seen a Bronze Age copper ingot, one of the most accurate descriptions in the history of archaeology.

The ingots were cast in a shape archaeologists call oxhide, a flat slab with four projecting corners that let two men grab them and haul them around.

His description got passed up the chain to the Institute of Nautical Archaeology, and when the professionals went down to look, they found the best preserved snapshot of the late Bronze Age economy that anyone has ever recovered. The excavation itself deserves a moment of appreciation, because it was miserable. The wreck lay on a steep slope between roughly 44 and 61 metres down, which in diving terms is the zone where the sea starts charging interest. At that depth, a person can work for about 20 minutes at a time, twice a day, and then has to spend a long stretch decompressing while staring at nothing.

George Bass and Chimal Pulak ran 11 excavation seasons between 1984 and 1994, and logged something in the neighbourhood of 22,000 individual dives, all to slowly lift a cargo that a modern forklift would clear in an afternoon.

Underwater archaeology is often described as glamorous by people who have never done it. It is mostly cold, dark, deliberate and full of paperwork, with the added feature that your workday ends whether or not you are finished. What they brought up rewrote the syllabus. The ship had gone down around 1320 BC, roughly a century and a half before everything fell apart, and it was carrying about 10 tonnes of copper in the form of 354 oxide ingots, plus a set of smaller bun-shaped ingots for good measure. Stacked in rows across the hull, the copper alone would have weighed more than a modern minivan. Alongside it sat roughly one tonne of tin, which is a much rarer and much more interesting substance, and we will come back to why in a moment. Then there were 175 ingots of raw glass in deep cobalt blue and turquoise. The earliest large stock of unworked glass ever found anywhere, apparently on its way to workshops that would turn it into beads and inlays for people who wanted their furniture to look expensive. The rest of the manifest reads like somebody emptied a museum into a boat. Canaanite storage jars packed with about a tonne of terebinth resin, a sticky aromatic gum used for incense and for scenting oil, which means a substantial portion of this cargo existed purely to make room smell nice, logs of African blackwood, the dense dark timber that Egyptian texts treat as a luxury import from the South, elephant tusk and a stack of hippopotamus teeth, the latter being the preferred raw material for small carved objects because the enamel is harder and holds a fine edge, ostrich egg shells, hollowed out and almost certainly intended as fancy containers because nothing says wealth like storing your cosmetics in a bird.
