Answer 2

It was an experiment which failed. A weakness was it was direct democracy - popular assemblies which made all the decisions were easibly swayed by demagogues and made unwise and often destructive decisions. Athens was pushed into war by self-interest groups, and the resulting 27-year war wrecked Greece. It was followed by other wars which let the Macedonians take control, and their kingdoms replaced democratic city-states.

Answer 3

After Pericles' death in Athens the citizens, already at war, were swayed by orators into wild adventurism and bad decisions, resulting in their defeat and being stripped of their empire. Lesser forms of democracy were introduced ,and eventually it became a formality.
