Spartiate in the context of "Conspiracy of Cinadon"

The Perioeci or Perioikoi (Περίοικοι, /peˈri.oj.koj/) were the second-tier citizens of the polis of Sparta until c. 200 BC. They lived in several dozen cities within Spartan territories (mostly Laconia and Messenia), which were dependent on Sparta. The perioeci only had political rights in their own city, while the course of the Spartan state exclusively belonged to Spartan citizens, or Spartiates.

The name perioeci roughly means "those dwelling around/nearby", deriving from περί, peri, "around", and οἶκος, oîkos, "dwelling, house". Perioeci and Spartans were collectively called the Lakedaimonians.

The agoge (Ancient Greek: ἀγωγή, romanized: agōgḗ in Attic Greek, or ἀγωγά, agōgá in Doric Greek) was the training program prerequisite for Spartiate (citizen) status. Spartiate-class boys entered it at age seven, and would stop being a student of the agoge at age 21. It was considered violent by the standards of the day, and was sometimes fatal.

The agōgē was divided into three age groups, paides, paidiskoi, and hēbōntes, roughly corresponding to young boys (7–12), adolescents (12–20), and young men (20–30). The agōgē deliberately deprived boys of food, sleep, and shelter. It involved cultivating loyalty to Sparta through military training (e.g., pain tolerance), hunting, dancing, singing, and rhetoric. There seems to have been ritual beating. It was intensely competitive, and the boys were encouraged to use violence against each other; by Plutarch's account, this included sexual violence by hēbōntes against paides, while Xenophon says the relationships were widely but wrongly considered to be sexual. Participants were required to live in the open or in barracks, and were restricted from contact with birth families or wives.

Mothax (Ancient Greek: μόθαξ, mothax, pl.: μόθακες, mothakes) is a Doric Greek word meaning "stepbrother".

The term was used for a sociopolitical class in ancient Sparta, particularly during the Peloponnesian War (431–404 BC). The mothakes were primarily either offspring of Spartiate fathers and helot mothers or children of impoverished Spartiates. Mothakes were not able to contribute to the syssitia, the core civic daily institution for citizens, and thus were not allowed to maintain an "equal" status. They were, however, permitted to fight as troops along with perioeci.

The Gerousia (γερουσία) was the council of elders in ancient Sparta. Sometimes called Spartan senate in the literature, it was made up of the two Spartan kings, plus 28 Spartiates over the age of sixty, known as gerontes. The Gerousia was a prestigious body, holding extensive judicial and legislative powers, which shaped Sparta's policies.

Ancient Greeks considered that the Gerousia was created by the mythical Spartan lawgiver Lycurgus in his Great Rhetra, the constitution of Sparta.
