Which greek city-state was known for it's democracy?

Athens pioneered democratic self-rule, but it was different from today's representative democracy. It was direct democracy where the adult male citizens met in fortnightly assembly and decided on issues of governance and politics - the council carried out its decisions.

Democracy comes from the Greek Words meaning 'people power'.

In today's representative democracy elected members of parliament direct governance, and are far less attuned to what their people really want until it comes time for new election promises in order to get re-elected.
