By Ḏḥwty, Contributing Writer, Ancient Origins The ancient Greek city-state of Sparta had a social hierarchy that was different from many of its neighbors. The top of the social pyramid was occupied by the two kings, whose powers were checked by a ‘council of elders’. These elders were chosen from the next class, the Spartiates. Below this aristocratic class was a middle class which was called the Perioeci. The lowest class, which was also the largest, in Spartan society was held a group known as the Helots.
