own assemblies under their local chiefs called Gramakas. Their administrations were divided into executive, judicial, and military functions. Scholars differ over how best to describe these governments, and the vague, sporadic quality of the evidence allows for wide disagreements. Some emphasize the central role of the assemblies and thus tout them as democracies; other scholars focus on the upper-class domination of the leadership and possible control of the assembly and see an oligarchy or an aristocracy. Despite the assembly's obvious power, it has not yet been established whether the composition and participation were truly popular. The first main obstacle is the lack of evidence describing the popular power of the assembly. This is reflected in the Arthashastra, an ancient handbook for monarchs on how to rule efficiently. It contains a chapter on how to deal with the sangas, which includes injunctions on manipulating the noble leaders, yet it does not mention how to influence the mass of the citizens—a surprising omission if democratic bodies, not the aristocratic families, actively controlled the republican governments. Another issue is the persistence of the four-tiered Varna class system. The duties and privileges on the members of each particular caste—rigid enough to prohibit someone sharing a meal with those of another order—might have affected the roles members were expected to play in the state, regardless of the formality of the institutions. A central tenet of democracy is the notion of shared decision-making power. The absence of any concrete notion of citizen equality across these caste system boundaries leads many scholars to claim that the true nature of s and 's is not comparable to truly democratic institutions. Sparta Ancient Greece, in its early period, was a loose collection of independent city states called poleis. Many of these poleis were oligarchies. The most prominent Greek oligarchy, and the state with which democratic Athens is most often and most fruitfully compared, was Sparta. Yet Sparta, in its rejection of private wealth as a primary social differentiator, was a peculiar kind of oligarchy and some scholars note its resemblance to democracy. In Spartan government, the political power was divided between four bodies: two Spartan Kings (diarchy), gerousia (Council of Gerontes (Elders), including the two kings), the ephors (representatives of the citizens who oversaw the Kings) and the ecclesia (assembly of Spartans). The two kings served as the head of the government. They ruled simultaneously, but they came from
