Bronze age collapse

The "Bronze Age Collapse" saw the fall of the Hittites and a general collapse of Aegean civilization, what there was of it. Otherwise, a series of disasters that may have been somewhat overstated as droughts, earthquakes and foreign invaders happen all the time. The big change was a transition from bronze to iron, eliminating the need for the extensive tin and copper trade and introducing much better weapons and implements.

Yes. I think the useful distinction is between the events of the collapse and their historical significance.

The conventional picture of the Bronze Age Collapse can make it sound like civilization in the eastern Mediterranean simply fell off a cliff around 1200 BCE: drought, earthquakes, invasions, famine, palace destruction, and then—darkness. But when you look at individual regions, it is considerably messier. Some cities were destroyed, some abandoned, some rebuilt, and some political systems simply changed. Egypt, for example, survived, although badly battered.

The Hittite case is particularly dramatic. The Hittite imperial state disappears around 1200 BCE, and its capital Hattusa was abandoned. But Hittite culture didn't vanish: successor states in northern Syria and southeastern Anatolia continued using Luwian/Hittite traditions for several centuries. So even there, "collapse" means the disappearance of a particular imperial political structure more than the disappearance of its civilization.

And I agree with your skepticism about the catalogue of disasters. Droughts and earthquakes are not explanations by themselves. The eastern Mediterranean had earthquakes before and after 1200 BCE, and droughts certainly weren't invented in 1200. What matters is that a highly interconnected system may have become unusually vulnerable to disturbances. If harvests fail while trade is disrupted, copper and tin become scarce, palace administrations lose their ability to redistribute food, and political legitimacy starts to evaporate, a fairly ordinary drought can have extraordinary consequences.

The technological point is especially interesting, though I'd modify it slightly. Iron did not suddenly replace bronze because it was inherently a vastly better material. Early iron was generally inferior to good bronze, and producing high-quality steel was quite difficult. What iron offered was something arguably more important: iron ore was abundant and widely distributed, whereas bronze required a supply chain bringing copper and, especially, tin together.

That makes the collapse of the long-distance trading system particularly consequential. A palace economy that depended upon imported tin to manufacture weapons and tools was vulnerable in a way that a society able to obtain iron locally was not. Iron technology therefore fits beautifully with the post-collapse world: less dependence on an elaborate international exchange network and more local production.

And eventually, once ironworking and steelmaking improved, you really did get the technological payoff: cheaper weapons and tools, agricultural implements, and eventually a much larger pool of people who could be equipped without maintaining the Bronze Age equivalent of a global strategic-minerals supply chain.

So I'd put it this way: the Bronze Age Collapse wasn't necessarily a single gigantic catastrophe. It may have been the failure of a particular kind of civilization—palace-centered, highly specialized, and heavily dependent upon long-distance trade—followed by a technological and political reorganization that made the successor world rather different.

In that sense, the most important thing that happened around 1200 BCE may not have been the earthquakes or the Sea Peoples at all. It was that the old system stopped being the only viable system.

 

OK I read what you say as the collapse of the trade for other reasons lead to iron technology getting better, while I'm thinking iron technology getting better led to collapse of tin and copper demand and hence the trade.

 

Ah—yes. I see the distinction, and your hypothesis is the more interesting one.

You're proposing a feedback direction:

Improved ironworking → reduced dependence on bronze → reduced demand for tin and perhaps copper → contraction of the long-distance metals trade → weakening of the palace economies that organized that trade → political collapse.

That's quite different from the usual "trade collapsed, therefore iron took over" story.

And it has a certain economic elegance. The Bronze Age international system was, in effect, partly organized around supplying the ingredients for bronze. Tin was the awkward one: relatively scarce in the Mediterranean world and therefore dependent on long-distance exchange. If societies discovered that iron could increasingly substitute for bronze, the economic foundation supporting that elaborate network would be undermined.

I would put one qualification on it: iron had to become good enough and cheap enough to displace bronze before this mechanism could operate on a large scale. Early iron wasn't automatically superior. But technological improvement doesn't have to mean "iron suddenly became a better metal." It could mean increasingly reliable smelting and forging, greater production, and eventually carburization/steelmaking.

There's also an intriguing chronological question here. If we could establish that significant improvement in iron production preceded the disruption of the bronze trade, your explanation would become much more compelling. Conversely, if the archaeological evidence shows that iron remained a minor material until after the palace economies had already collapsed, then my direction of causation would win.

And there's a third possibility I rather like: both processes reinforced each other. Improved ironworking began eroding bronze's economic advantage; that weakened the trade network; the disruption then made locally available iron even more attractive; increasing iron production further reduced the demand for imported tin.

That would make the "collapse" less like a civilization being hit by a hammer and more like a technological substitution causing a network effect to unravel. Much more interesting than blaming everything on a drought and a bunch of Sea Peoples.

Technology involves winners and losers in complex, hard to discern, relationships.

Exactly. And that's why I think technological change is often badly represented as "new technology arrives, old technology disappears." Real history is more like an ecological system.

A technology can create winners at one level and losers at another. Ironworking might benefit the farmer who can obtain an iron plow or the small community that can make its own tools, while hurting the tin miner, the caravan operator, the bronze smith, the merchant, and ultimately the palace that collected taxes on the whole chain.

And there are second- and third-order effects. If the palace loses revenue from the metals trade, it may be less able to maintain armies. If it can't maintain armies, peripheral provinces become independent. That disrupts trade further. Merchants disappear, local production becomes more attractive, and the original technological change gets accelerated by the political consequences it helped produce.

So causation can run in both directions simultaneously. There needn't be a single "cause" of the Bronze Age transformation.

It's rather like what happened with mechanization much later: a machine doesn't merely replace a particular worker. It changes prices, demand, capital requirements, transportation, settlement patterns, skills, and eventually which businesses are viable. The interesting historical question isn't "Did technology X cause event Y?" but "What network of people and institutions was technology X making more and less viable?"

Which is also why I'm wary of tidy explanations of the Bronze Age Collapse. We may be looking at the archaeological residue of a large technological-economic reorganization, and trying to explain it with a list of catastrophes because catastrophes leave more obvious archaeological fingerprints.

I think the tendency to see a catastrophe at the border of the bronze and iron ages is mainly from Greek scholarship, as in Greece literacy disappeared, cities burnt and population collapsed. This however was several centuries in the doing and was quite different most other places.

Yes, and I think that's an important historiographical point. The Greek experience is unusually dramatic and unusually well positioned to shape the story we tell about the period.

The Mycenaean palace system really did undergo something close to a catastrophe: the palaces were destroyed, Linear B literacy disappeared, settlements contracted or were abandoned, and population fell substantially. And because the Greeks subsequently experienced a genuine centuries-long interruption of their own literate palace civilization, it is tempting to project that experience onto the whole eastern Mediterranean and call the whole thing "the collapse."

But elsewhere the picture is much less binary. Egypt's state survived; Cyprus underwent major changes but remained connected to Mediterranean networks; the Levant had substantial continuity and then the emergence of new political entities; and Anatolia saw the disappearance of the Hittite empire but continuation of Hittite/Luwian traditions in successor states.

There's an especially interesting irony in the Greek case: we know about the Mycenaean collapse precisely because literacy had existed immediately beforehand and then disappeared. That makes the discontinuity unusually conspicuous archaeologically. A society that remains illiterate throughout can undergo enormous political and economic changes without producing a comparable "loss of literacy" marker.

And I agree with your point about the timescale. Calling it the Bronze Age Collapse around 1200 BCE encourages us to imagine a synchronized event. In reality, the transformations varied enormously in date, severity, and character, and some continued for generations or centuries.

It also makes your technology argument more plausible as a process rather than an event. If bronze-based economic and political arrangements were gradually becoming less advantageous while iron technology was spreading, you wouldn't expect a single archaeological moment when somebody announced, "The Bronze Age is cancelled." You'd expect regional systems to unravel at different speeds, with some places experiencing destruction and depopulation while others simply reorganized.

The Greeks then provide the spectacular example that became the shorthand for the whole phenomenon. "Collapse" may tell us as much about the peculiar trajectory of Greece—and about the survival of the Greek memory of that trajectory—as it does about what happened everywhere around the Mediterranean.
