In short
In 508 BCE, the Athenian statesman Cleisthenes dismantled the power of aristocratic clans and introduced democratic reforms that gave ordinary male citizens a voice in government. By reorganizing the city into new voting districts (demes) and establishing the Council of 500, he created the structural foundation for direct democracy. This shift from elite rule to citizen participation would define Athens for the next two centuries and influence Western political thought ever since.
How it unfolded.
The five-minute version
What actually happened.
Athens, was a prominent city-state (polis) of ancient Greece during the classical period, in the peninsula of Attica. Athens was a centre for the arts, learning, and philosophy, and is widely referred to as a cradle of Western civilization largely due to the impact of its cultural and political achievements during the 5th and 4th centuries BC. Athenian democracy was established in 508 BC and, with a few brief interruptions, remained in place for 180 years.
