    My understanding (not a historian, don’t quote me on this) is that one of the big explanations for the collapse was particularly bad famine that affected the entire region. It led rural people to migrate into relatively-more-prosperous cities, often by boat (hence “sea people”), but this migration led to increased strain on city infrastructure, especially since the cities were facing the famine as well.
