Highly recommend the Fall of Civilizations podcast episode on the Bronze Age Collapse to learn more about the Sea-Peoples (https://youtu.be/B965f8AcNbw?list=PLR7yrLMHm11XAuYuZMPHPn9Hz...) . They discuss how the Sea-Peoples may be a symptom and a cause of the bronze age collapse, and the whole episode is extremely engaging and educational. (As all the episodes of this podcast are, cannot recommend it enough)
I second this recommendation. This particular episode is unfortunately one of the shorter ones, but it is very good. The entire podcast (at 18 episodes as of today) is brilliant.
