It wasn't just Greece: Archaeologists find early democratic societies in the Americas

[Eric the Green]

Tribal societies worldwide were more "democratic" than the city-states and empires of early civilization, whose influence remained strong in its later phases. European Dark Age tribes were less autocratic than the royal states that came later. It seems according to the article that some societies in Mesoamerica were ruled by more than one autocrat; they may not have been democracies, but there was some ability to bring others into the ruling of society, and awareness of satisfying the needs of the people.
