The democratic government of Athens rested on three main institutions, and a few others of lesser importance. The three pillars of democracy were: the Assembly of the Demos, the Council of 500, and the People’s Court. These were supplemented by the Council of the Areopagus, the Archons, and the Generals. Actual legislation involved both the Assembly and the Council, and ad hoc boards of “Lawmakers.”
In the Assembly each male citizen of Athens could speak, regardless of his station…
Under the Democracy of Aristotle’s time (after 330 BCE), young men were enrolled on this list when they were 18 years old , then spent two years as military cadets, or ephebes, after which they were members of the citizen body (i.e. Freemen became voting citizens at age 20)…
In the 5th century we can estimate the adult male population of Athens, and thus the number of men eligible to participate in an Assembly, to have been 40,000 - 60,000, and in the 4th century, 20,000 - 30,000…
Thucydides makes the statement that during the Peloponnesian War (431 - 404 BCE) there were usually only 5000 people at a meeting…
Citizens were paid for attending the Assembly, to ensure that even the poor could afford to take time from their work to participate in their own government…
Most voting in the Assembly was by a show of hands, although some votes were conducted by secret ballot. Even the most serious of matters were often decided by show of hands, such as the impeachment and condemnation of generals and the approval of formal laws…
The Council of 500 represented the full-time government of Athens. It consisted of 500 citizens, 50 from each of the ten tribes, who served for one year. The Council could issue decrees on its own, regarding certain matters, but its main function was to prepare the agenda for meetings of the Assembly…
Aristotle lists service on the Council among those offices chosen by lot . He elsewhere says that in a democratic city, the Council was the most important board of magistrates Through most of the 5th and 4th centures BCE, citizens were paid for their participation in the Council, and each citizen could serve on the Council twice in his lifetime…
A citizen had to be 30 years old to serve as a Councilor. For the sake of argument, we might assume that the average citizen would then have an active political life of 30 years, until he was 60. During that time, there would need to be approximately 10,000 chairmen, each controlling the state seal and the treasuries, and presiding over the presidents of the Council for a day and a night . Since no one could serve as chairman twice, this office would have to go to 10,000 different Athenians. It follows, then, that approximately one half of all Athenian citizens would, at some point during their lives, have the privilege and responsibility of holding this office, arguably the closest equivalent to a Chief Executive in the Athenian democracy…
Council of the Areopagus… was primarily the court with jurisdiction over cases of homicide and certain other serious crimes. After an Athenian had served as one of the nine archons, his conduct in office was investigated, and if he passed that investigation he became a member of the Areopagus; tenure was for life…
Of almost equal importance to the Assembly and Council, and probably of greater importance (if not greater prestige) than the Areopagus was the People’s Court, the Heliaea and other courts where juries of citizens would listen to cases, would vote on the guilt or innocence of their fellow citizens, and vote on punishments for those found guilty…
Athenians who served on juries received one-half drachma a day, or three obols, for their service…
There was no property requirement for service; any citizen who did not owe any debts to the treasury, was at least thirty years old, and had not lost his citizenship through any legal action could serve as a juror…
Juries varied in size from 501 jurors in lesser cases, up to 1500 for the most important matters…
