Ancient Greece is credited with developing the concept of democracy, particularly during the 5th century BCE in the city-state of Athens. This early form of democracy was characterized by direct participation of citizens in decision-making processes, where they could vote on legislative and judicial matters. The Athenian model allowed free male citizens to engage in public life, although it excluded women, slaves, and non-citizens. This democratic system laid the groundwork for later democratic principles and institutions around the world, influencing political thought and governance through the ages.
