Athens' rise to power during the Archaic Period shaped ancient Greece. From 800 to 480 BCE, key reforms by Solon and Cleisthenes laid the groundwork for democracy. The city-state system emerged, and Greek culture flourished through art, literature, and philosophy. Political and economic changes transformed Greek society. The development of coinage, expansion of trade, and military innovations like the hoplite phalanx strengthened city-states. Athens' victory over Persia at Marathon in 490 BCE cemented its growing influence in the region.
