1177: The Year Civilization Collapsed, Eric Cline
The Bronze Age Collapse has historically been one of the great mysteries of history. While we know that several societies in the Aegean and Eastern Mediterranean collapsed or fell on hard times during, roughly, the 12th century BCE, the causes are a source for speculation and debate even today. This book is a good, well-written and up-to-date account of both the collapse and the leadup. Interesting seeing how all the societies from Egypt up through the Levant and Asia Minor to Crete and Mycenean Greece were connected economically and diplomatically in an early form of globalization and then how that all fell apart in the collapse. I am reading the 2021 edition which was updated with new data supporting the core hypothesis, that a massive drought in the Mediterranean and Near East was a major factor. Good book if you're into ancient history or just how civilizations rise and fall.
(And even Cline concedes that the date in the title is mostly his publisher's doing. The collapse actually happened over a period of decades, not in a single year.)
