 Dark Ages, it was a period associated with the collapse of central authorities, a general depopulation, particularly of highly urban areas, the loss of literacy in Anatolia and the Aegean, and its restriction elsewhere, the disappearance of established patterns of long-distance international trade, increasingly vicious intra-elite struggles for power, and reduced options for the elite if not for the general mass of population.

There are various theories put forward to explain the situation of collapse, many of them compatible with each other.

Earthquakes

Amos Nur shows how earthquakes tend to occur in "sequences" or "storms" where a major earthquake above 6.5 on the Richter magnitude scale

 chariotry. This argument has been weakened of late with the finding that the shift to iron occurred after the collapse, not before. It now seems that the disruption of long distance trade, an aspect of "systems collapse", cut easy supplies of tin, making bronze impossible to make. Older implements were recycled and then iron substitutes were used.

On the other hand, technology cannot be so quickly dismissed as a factor. The invention of the technology of metallurgy is not generally regarded as a Paradigm Shift, in a class with the technologies of agriculture, city-building, industry and electronics. Yet metalworking had a profound impact on the course of mankind's development. Warfare on the scale with which we are familiar today was not possible when sharpened sticks and flint points and blades were the only weapons available. The first bronze swords and armor were surely regarded as "weapons of mass destruction" by the last inhabitants of stone age cities because of the carnage they made possible.

Still, the very nature of bronze, an alloy of copper and tin, forces at least a grudging equilbrium on man's violent nature. Deposits of copper ore and tin ore almost never occur in the same region. In order to make bronze, two cities a fair distance apart must maintain peaceful relations and trade raw materials with each other.

Iron metallurgy destroyed this equilibrium. Only one ore is required to make iron artifacts, and deposits of it are abundant. The only trick to smelting iron is the creation of hitherto unimaginably high temperatures, because the melting point of iron is hundreds of degrees higher than that of copper and tin. But once that information became well known, there was nothing to stop even the most uncivilized of the remaining Neolithic tribes from arming their warriors, proclaiming themselves "kingdoms," and attacking the cities. Even worse, the cities were no longer dependent on each other for complementary ores, and had no more reason to maintain peaceful relations.

The Iron Age may not have been the cause of the collapse of civilization in its first place of origin, but it is difficult to dismiss iron as a possible reason for its slow recovery.

 for 35 Greek, Turkish, and Middle Eastern weather stations, showed that a drought of the kinds that persisted from January 1972 would have affected all of the sites associated with the Late Bronze Age collapse. Drought could have easily precipitated or hastened socio-economic problems and led to wars. More recently Brian Fagan, has shown how the diversion of mid-winter storms from the Atlantic were diverted to travel north of the Pyrenees and the Alps, bringing wetter conditions to Central Europe, but drought to the Eastern Mediterranean, was associated with the Late Bronze Age collapse

 who shows how social declines in response to complexity often leads to a collapse that results in simpler forms of society.

In the specific context of the Middle East a variety of factors - including population rise, soil degradation, drought, cast bronze weapon and iron production technologies - conceivably could have combined to push the relative price of weaponry, compared to arable land, to a level that ultimately proved to be beyond the control of traditional warrior aristocracies.
