Not gonna lie, I AM using this for an assignment, so feel free to give sources rather than direct information (although direct information means less work for me :P). I'm looking specifically at the nearby area and influences that came from other civilisations at the time.
Feel free to vent anything you know about the subject!
Thanks
Not enough is known for us to draw firm conclusions. However, there are many competing hypotheses. Many of them are worth considering, analysing, and critiquing. The best one-stop critique of these hypotheses is in Robert Drews' 1993 book The End of the Bronze Age (Princeton), pp. 33-94.
Drews' own suggestion, laid out in the following 120-odd pages, is about as strong as the ones he critiques -- which is to say, not very, but still worth considering.
