This is important stuff! The roots of democracy run deep, and wide — ancient history was not all ruled by pharoahs, emperors, and gilded billionaires.
An article describes research I never heard of that shows that there was in fact quite a continuum from pure democracy to pure autarchy in past history — and if we look carefully at clues left behind in the archaelogical record, we can get an idea of how democratic (0r not) various ancient societies actually were.
They come up with a scale of popular participation in government that runs from autocratic regimes to more collective or democratic regimes. In their causal model the internal or external origin of state revenues causes or determines the scores on the governance scale (see the diagram). In short, reliance on internal revenue sources leads to greater bureaucratization, greater popular control over rulers, and more provisioning of public goods. Rulers rely on their subjects for taxation, so they must treat them better. External revenue leads to the opposite pattern. Rulers get their revenue from elsewhere, so they have no incentive to treat their subjects well by providing public goods or giving them any say in governance.

Blanton and Fargher’s scale of rulership, which runs from autocratic to democratic or collective, is a major advance in understanding ancient states. Not all states were the same. Some rulers were despotic and seriously exploited their subjects, but other states had more collective forms of rule, which means that commoner subjects had some say in governance. They analyze the thirty polities in their sample on a host of variables, which are scored in various ways to produce three numerical scales: public goods provision; bureaucratization; and control of the ruler. The scores for these scales are summed to produce their governance scale, which runs from a low of 23.5 (Bakitara; Aceh, Nupe, and 12th century England are near the bottom) to a high of 52 (Classical Athens; also near the top: Republican Rome, Ming China and Lozi in Africa).
