The development of democracy in ancient Athens was a gradual process that dismantled hereditary privilege in favor of citizen participation.12

Early Foundations

The foundations were laid by Solon in 594 BCE, who replaced the monopoly of the nobility with a system based on wealth. He established the Ecclesia (Assembly) as a sovereign body and created a Council of Four Hundred to prepare its agenda, providing a voice to lower-income classes.34

The Cleisthenic Reforms

Cleisthenes, regarded as the founder of Athenian democracy, transformed the system in 507 BCE by shifting the basis of political organization from kinship to locality. He reorganized citizens into 10 tribes based on residence in demes, effectively breaking the power of old aristocratic clans.124

Key institutions included:
* The Assembly: The heart of government, where citizens voted on policy.14
* The Council of Five Hundred: Composed of representatives chosen by lot, it set the Assembly's agenda.14
* The Popular Courts (dikasteria): Jurors chosen by lot held significant power to oversee magistrates and leaders.1

These reforms promoted isonomia, or equality of rights, ensuring broader participation in public life until the system was eventually curtailed by Macedonian influence and Roman conquest.12
