 Despite speculation that Knossos was destroyed by the volcanic eruption on Santorini, it is generally accepted that the cause was human violence following an invasion of Crete by Greeks from the Argolid, most probably Mycenaean.Knossos was still prosperous at the time of its destruction c. 1,370 with trade and art continuing to thrive.Explanations for its destruction are speculative, but a likely reason is that the Mycenaeans, now prospering on the mainland, decided to remove a rival power.
