Minoan civilization expand their influence. It is likely that the original hierarchies of the local elites were replaced by monarchies, a precondition for the palaces. At the end of the MMII period (1700 BC) there was a large disturbance on Crete—probably an earthquake, but possibly an invasion from Anatolia. The palaces at Knossos, Phaistos, Malia and Kato Zakros were destroyed. At the beginning of the neopalatial period the population increased again, the palaces were rebuilt on a larger scale and new settlements were built across the island. This period (the 17th and 16th centuries BC, MM III-Neopalatial) was the apex of Minoan
Minoan civilization among the most well-supported examples known. Because their language has yet to be deciphered, it is unknown what kind of government was practiced by the Minoans, though the palaces and throne rooms indicate a form of hierarchy. A fresco of saffron-gatherers at Santorini is well-known. The Minoan trade in saffron, the stigma of a naturally-mutated crocus which originated in the Aegean basin, has left few material remains. According to Evans, the saffron (a sizable Minoan industry) was used for dye. Other archaeologists emphasize durable trade items: ceramics, copper, tin, gold and silver. The saffron may have had a religious significance.
