Archaic Greece was the period in Greek history lasting from the eighth century BC to the second Persian invasion of Greece in 480 BC, following the Greek Dark Ages and succeeded by the Classical period. The period began with a massive increase in the Greek population.
The Archaic period saw developments in Greek politics, economics, international relations, warfare, and culture.
Though in the early part of the Classical period the city of Athens was both culturally and politically dominant, it was not until the late sixth century that it became a leading power in Greece.
The earliest laws of Athens were established by Draco, Draco's law code aimed to replace private revenge as the first and only response of an individual to an offence committed against them.
Sparta's constitution took on the form it would have in the Classical period during the eighth century BC. The First Messenian War, saw the strengthening of the powers of the Gerousia against the assembly, and the enslavement of the Messenian population as Helots Around the same time, the ephors gained the powers to restrict the actions of the kings of Sparta.
From around 560 BC, Sparta began to build a series of alliances with other Greek states, which became the Peloponnesian League: by 550, cities such as Elis, Corinth, and Megara would be part of the alliance.
