The Athenian Assembly, known as the Ekklesia, was a central institution in ancient Athens where citizens gathered to discuss and make decisions on important political matters. All male citizens over the age of 18 could participate, allowing them to vote on laws, policies, and other civic issues. Meetings typically occurred on the Pnyx hill, where citizens could openly debate and express their opinions. The Assembly played a crucial role in the development of democracy in Athens, as it provided a platform for direct participation in governance. Decisions made by the Assembly could influence military actions, public finances, and the appointment of officials, reflecting the collective will of the citizenry.
