  Eric Cline makes a good case that the Bronze Age empires were organized around a “palace economy”, where only certain people (royals & their pals) were even allowed to trade. In some places the sovereign literally owned all the land and people on it.One can imagine that a series of bad seasons, natural disasters, invasions & other stressors would open a window for revolt.Yes tin was a factor, yes the “Sea Peoples” were a factor. But you don’t get the wholesale overthrow of so many empires without the common people being at least somewhat welcoming of the invaders (when not happily assisting them!) in throwing off centuries of elite oppression.

  Well, doesn’t the Harappan civilization make a mess out of all this? Tin was nearby, and there’s evidence of bronze artifacts in all kinds of houses across the cities, and in general less evidence of hierarchical power, and certainly nothing like the concentration you see in other Bronze Age civilizations. We don’t have the civilization surviving as is to the Iron Age, because it depopulated before iron smelting became common. But it’s odd to make the claim bronze had to lead to stratified societies. Clearly, not always.

  Long before the so-called “iron age” started, humans knew of iron. There are iron artifacts from the 4th millennium BCE. Humans were fascinated by these small pieces of iron, which were found in meteorites and cherished and valued them. However, usable iron was rare and extremely sought after to the extent that we know it was more valuable than gold or silver. How did humans invent the first technique to produce metallic Iron from ore?The story of Iron starts with the production of Bronze. Bronze is an alloy of 90% copper. Depending on what constitutes the other 10% we get different types of bronze. The most common type which kick started the bronze age around 3500 BCE in western Asia is tin bronze. Unlike copper ore, tin is hard to find but a small amount of it can significantly improve the quality of copper and make it usable and strong. Ancient smelters produced bronze by melting the natural copper ore mixed with tin ore in simple kilns. The resulting bronze was the primary metal used in tools and arts for more than 2500 years.Iron is a common impurity in copper ores. We also know that iron ore can, and was, used as a flux in the process of smelting copper. In simple terms, a flux agent is a chemical that attracts oxygen to itself and protects the primary product, which is copper, from oxidizing in high temperatures. Therefore, across the ancient world, bronze smelters had been encountering molten iron when they raised the kiln temperature high enough. However, they discarded the resulting metal because its copper impurity made it too soft and inferior to bronze.Around 1,200 BCE the collapse of bronze age civilizations in the near east due to a “perfect storm” of drought, famine, disease, immigration and war affected trade routes that brought tin ore to the western Asia. During this time of bronze shortage some smelters seem to have resorted to using the lower quality iron for tool making. They had observed that adding carbon to iron makes it much harder but prone to breaking. We have evidence of iron tools built with layers of soft and hard iron to achieve desired outcomes. Over time iron smelters experimented with different amounts of carbon impurity and achieved desired levels of hardness and strength.

  This was a fascinating article, and the theory that the availability of iron prevented big empires seems to make sense. But then I don't get how later big empires (e.g., Athenian Empire and eventually Roman Empire) formed. What changed that allowed big empires to form even in the presence of iron?

  Fun article. I think that there is a lot of interesting information here that would help explain what we saw with the Bronze Age Collapse, though I would submit that this is just another of the multiple factors that led to the collapse. Maybe a drought occurs, folks turn to iron weapons, and then take over another town or village for their resources, and so on.This could lead to supply chain collapses and such. Maybe just general destabilization and raids and such sort of collapsed the larger empires. But at the same time, those larger empires would also have had access to iron, so why couldn't they by matter of numerical superiority, access to greater resources, tactics and military organization, and more simply, overwhelm smaller armies or bands utilizing the same technology and restore order or at least defend themselves?I just started reading Conrad Black's historical series and in the Egyptian chapter and also the Assyria/Babylonia chapter he references the historical accounts where time and time again Egyptian forces led by the pharaoh would march into the broader Middle East to restore order. Why couldn't they continue to do that?

  Interesting : "some also alluded to the idea that iron had democratized violence"

  Reminds me of this awesome quote from Ramses III after driving back the Sea Peoples[1]1: https://www.youtube.com/clip/Ugkxi2veZE2Uvm0VQUbAjGROCQoILO8...

  I thought this was a cool fact about the Bronze Age: "According to a new study, it's possible that all iron-based weapons and tools of the Bronze Age were forged using metal salvaged from meteorites".[0][0]: https://www.sciencealert.com/bronze-age-artefacts-have-meteo...

  This is a thesis and it's not a new one.It's true that when iron was first smelted and the first steel was made, it was structurally different to the Bronze economy. Iron is abundant and local. It doesn't require the same trade network (of copper and tin).I'm surprised this article doesn't mention the Uluburun shipwreck [1]. It's archeologically important because it provides primary evidence of how extensive Bronze age trade networks were.At best the author is theorizing not why the Bronze age collapse happened but why the empires and trade networks of that era didn't come back. But that's a different question.We also have direct primary evidence from this time of the Sea Peoples [2]. To this day nobody really knows where they came from or why. Many modern scholars believe they may have been refugees themselves, possibly from natural disasters or droughts.The most likely explanation for all this is that there was no single factor. All of these things likely contributed. It's still unclear why the collapse was so extensive and relatively sudden. That's not really satisfying but we've had fragile systems before that have collapsed suddenly and violently. Look at the outbreak of World War One as one major example.One of my favorite phrases here is Outside Context Problem [3], which originates from the Iain M. Banks Culture novel Excession (love this book). It pretty accurately describes the collapses that happened in the Americas in the colonial era.[1]: https://www.re-thinkingthefuture.com/case-studies/a9360-lost...[2]: https://en.wikipedia.org/wiki/Sea_Peoples[3]: https://tvtropes.org/pmwiki/pmwiki.php/Main/OutsideContextPr...

  We will likely never know the exact causes because there is a certain fog that hovers that period of history.In my opinion, whatever caused that fog (confusion, conflicted or coded accounts, apocalyptic and prophetic writings) *IS* what caused the collapse.Technology likely plays a role, but as a catalyst to a sociological phenomena. The industrial revolution did something similar (lots of new philosophy with somehow apocalyptic or prophetic undertones, albeit in a different style; war and depression in the following decades; confusion and a fog in history). We're still not over that, and it's only barely visible because we live inside this particular fog, but it's likely to confuse future historians a lot. I see AI as belonging to the same wave.

  Interesting fact, you only could come third in the Olympics during the bronze age
