Evidence record
Why did the Bronze Age collapse?
Every sentence on the exploration belongs to at least one claim below. Each says what kind of statement it is, what it rests on, what the evidence does not establish, and how far it was checked. Nothing here is a score, and none of it is a verdict on a belief or a theory.

What the question takes for granted
A historical and archaeological question with a climate strand. What ended and roughly when is well recorded; why is argued, and the evidence for each cause is of a different kind.
There was a single collapse to explain
Contested
The palace states of Greece, the Hittite empire and Ugarit did end within a few decades. Whether that is one collapse, marked by one horizon of destruction, is argued: a recent reassessment rejects most of the destructions proposed for about 1200 BC, and the Gordion team prefers to call the change a transformation.
A drought coincided with it
Established
Pollen records from Cyprus and Syria, isotope records from Israel and tree rings from central Anatolia all record dry conditions around 1200 BC. How dry, how uniform across the region, and how exactly timed are still being worked out.
The collapse has one cause
Contested
The question asks why, in the singular. None of the sources read offers one cause: drought, raiders, systems failure and internal conflict are all argued, and the climate papers themselves present climate as context or pressure rather than as the whole story.

- Review
- A judgement, not a fact. Reviewed for whether it is fairly put and follows from the checked claims. No source can confirm it.
