I'm notoriously concerned of your intentions of this website- what do you want with this information?
In Greek democracy, only male citizens above 18 had true power to vote and have say in government. Today, everybody in the country has that right. There are also some differences in the bodies of governing power, but I don't know too much about them, so I won't say anything because I wouldn't want to give you wrong information. :)
