The density of their connection can be learned from trade goods found in shipwrecks, from Egyptian hieroglyphs and wall paintings, and from countless well preserved clay-tablet letters written between the states. The tin required for all that bronze (tin was the equivalent of oil today) came from Afghanistan 1,800 miles to the east. It was one of history’s most globalized times.
In the 12th Century B.C. everything fell apart. For Cline the defining moment was the battle in 1177 B.C. (8th Year of Ramses III) when Egypt barely defeated a mysterious army of “Sea Peoples.” Who were they? Do they really explain the general collapse, as historians long assumed?
Cline thinks the failure was systemic, made of cascading calamities in a highly interdependent world. There were indeed invasions—they might have been soldiers, or refugees, or civil war, or all three. But the violence was probably set in motion by extensive drought and famine reported in tablet letters from the time. Voices in the letters: “There is famine in our house. We will all die of hunger.” “Our city is sacked. May you know it! May you know it!” In some regions there were also devastating earthquakes.
The interlinked collapses played out over a century as central administrations failed, elites disappeared, economies collapsed, and whole populations died back or moved elsewhere.
In the dark centuries that followed the end of the Bronze Age, romantic myths grew of how wondrous the world had once been. Homer sang of Achilles, Troy, and Odysseus. Those myths inspired the Classical Age that eventually emerged.
Cline wonders, could the equivalent of the Bronze Age collapse happen in our current Age?
