During the Archaic Age in Athens from 800 to 600 BC, Athens experienced significant changes including influences from other civilizations, migration due to population growth, and the rise of city-states. Power began to shift from noble families to commoners as the importance of hoplites grew and Solon and later Cleisthenes implemented reforms granting more rights to commoners and establishing democracy. However, citizenship excluded women, slaves, and foreigners, and Athens relied on slavery for its economy and workforce. The democracy gave all citizens a direct role in political decisions through the Assembly. The Peloponnesian Wars from 431 to 404 BC marked the end of Athens' golden age as it was defeated by Sparta.
