The Bronze Age Energy Crisis
28th August 2025
Civilisations seldom collapse because of a single drought, battle, or angry god. Such events dominate chronicles because they are spectacular, but they are more symptom than cause. What usually undoes a complex society is the loss of surplus energy—the margin that makes coordination across distance possible and that keeps interdependent parts working in sequence. When that margin narrows, systems fray first at the edges and then at the centre, until the framework that once held them together can no longer carry the weight of its own complexity.
The decline usually begins with smaller problems in daily life: first, deliveries arrive late; then they stop; then workshops fall idle for lack of fuel. In tightly coupled economies built on just-in-time logistics, one interruption can bring transport to a standstill and darken cities. The crisis is not only material—it touches institutions like law and bureaucracy, which also rely on steady flows of energy to function.
The Bronze Age Collapse, which occurred around 1200 BC, involved not only the fall of cities but the unravelling of an entire way of life, as palaces burned, trade networks across the Aegean and Near East dissolved, and populations fragmented into modest rural settlements. For centuries afterwards, much of the Eastern Mediterranean retained only a much smaller repertoire of skills and a more rudimentary set of institutions, which is why archaeologists have traditionally described the period as a “dark age.”
