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
Cypro-Minoan syllabary decipherment. Currently, the total number of signs on formal Cypro-Minoan inscriptions (approx. 2,500) compares unfavorably with the number known from the undeciphered Linear A documents (over 7,000) and the number available in Linear B when it was deciphered (approx. 30,000). Furthermore, different languages may have been represented by the same Cypro-Minoan subsystem, and without the discovery of bilingual texts or many more texts in each subsystem, decipherment is extremely unlikely. According to Thomas G. Palaima, ""all" past and current schemes of decipherment of Cypro-Minoan are improbable". Silvia Ferrara also believes this to be the case, as she concluded in her
