Athenian Democracy was a system of government developed in ancient Athens around the 5th century BCE. It was characterized by direct participation of citizens in decision-making, where eligible male citizens could vote on laws and policies. This form of democracy allowed for public debates and assemblies, giving citizens a voice in their governance. In Athenian Democracy, key institutions included the Assembly, where citizens gathered to discuss and vote, and the Council of Five Hundred, which prepared the agenda for the Assembly. However, this system excluded women, slaves, and non-citizens, limiting participation to a small segment of the population.
