What happened 650 AD

The Etruscans were a dominant culture in Italy by 650 BC, surpassing other ancient Italic peoples such as the Ligures. Their influence may be seen beyond Etruria's confines in the Po River Valley and Latium, as well as in Campania and through their contact with the Greek colonies in Southern Italy (including Sicily).

In Sparta, the Messenian Wars resulted in the conquest of Messenia and the enserfment of the Messenians, beginning in the latter half of the 8th century BC. This was an unprecedented act in ancient Greece, which led to a social revolution in which the subjugated population of helots farmed and labored for Sparta, whilst every Spartan male citizen became a soldier of the Spartan Army permanently in arms. Rich and poor citizens alike were obliged to live and train as soldiers, equality which defused social conflict. These reforms, attributed to Lycurgus of Sparta, were probably complete by 650 BC.

This seems to have introduced tension to many city-states, as their aristocratic regimes were threatened by the new wealth of merchants ambitious for political power. From 650 BC onwards, the aristocracies had to fight to maintain themselves against populist tyrants. A growing population and a shortage of land also seem to have created internal strife between rich and poor in many city-states.
