Show the answer
Bronze is copper plus roughly 10% tin — and because that ingredient is rare and never near the copper, arming a palace required a supply chain thousands of kilometres long.

A tenth of the recipe generates the whole geopolitics of an age. Change that one ingredient to something local and the Bronze Age’s entire structure of dependency evaporates, which is roughly what iron did.
