Where did democracy originated in?

It is likely that History does not record the origin of Democracy. The Greeks and Romans were known to have elections yet the eligible voters of these societies were only a small percentage of the people.

Machiavelli in "Discourses on Livy" suggest that democracies have existed for as long as history was recorded.

John Lock in his "Second Trieste on Government" suggest that democracy may be the oldest form of government outside of a Patriarchy.
