Quick questions on Spartan social structure: HSC Ancient History

The Spartiates were the citizen-warrior class. They called themselves "Homoioi" (the Equals or Peers), implying equality of status, training, and citizenship.

The Perioikoi ("dwellers around") were free non-citizens living in around 70 to 100 outlying poleis in Laconia and Messenia. They had local self-government within their own communities but were subject to Sparta in foreign and military affairs.

The Helots were state-owned serfs, the descendants of the conquered Laconian and (especially) Messenian populations enslaved after the Messenian Wars (c. 740-720 BC and c. 670-650 BC).

Plutarch (Lycurgus 28) records that the ephors declared war on the Helots each year on entering office, so that killing a Helot was not legally murder. The custom likely dates back to the late 7th century BC.

Young Spartiates near the end of the agoge underwent a phase in the Krypteia ("secret service"). They lived alone in the countryside, killing Helots judged to be strong or dangerous. Plutarch (Lycurgus 28) is the main source; Thucydides (4.80) describes a related episode in which 2,000 Helots were promised liberation, paraded around the temples wearing garlands, and then disappeared, "no one being able to say how."

Spartiates were discouraged from foreign travel, partly to prevent Helot rebellions in their absence.

Spartiates who failed the qualifications (often because of poverty and inability to maintain the syssition contribution). They retained personal freedom but lost citizenship.

Sons of Spartiate fathers and Helot mothers (or otherwise irregular status) who completed the agoge alongside Spartiate boys. Some, like Gylippus and Lysander, rose to military command despite their irregular origin.

Helots freed in return for military service, particularly during the Peloponnesian War. By the 4th century BC they were a substantial fighting force.

Spartiates who showed cowardice in battle and lost civic rights as a result.
