Helots in the context of "Gylippus"

Slavery was a widely accepted practice in ancient Greece, as it was in contemporaneous societies. The principal use of slaves was in agriculture, but they were also used in stone quarries or mines, as domestic servants, or even as a public utility, as with the demosioi of Athens.

Modern historiographical practice distinguishes between chattel slavery slavery (where the slave was regarded as a piece of property, as opposed to a member of human society) and land-bonded groups such as the penestae of Thessaly or the Spartan helots, who were more like medieval serfs (an enhancement to real estate). The chattel slave is an individual deprived of liberty and forced to submit to an owner, who may buy, sell, or lease them like any other chattel.

Epaminondas (/ɪˌpæmɪˈnɒndəs/; Ancient Greek: Ἐπαμεινώνδας, romanized: Epameinōndas; 419/411–362 BC) was a Greek general and statesman of the 4th century BC who transformed the Ancient Greek city-state of Thebes, leading it out of Spartan subjugation into a pre-eminent position in Greek politics called the Theban Hegemony. In the process, he broke Spartan military power with his victory at Leuctra and liberated the Messenian helots, a group of Peloponnesian Greeks who had been enslaved under Spartan rule for some 230 years following their defeat in the Second Messenian War ending in 600 BC. Epaminondas reshaped the political map of Greece, fragmented old alliances, created new ones, and supervised the construction of entire cities. He was also militarily influential and invented and implemented several important battlefield tactics, such as the oblique order.

Xenophon, the historian and contemporary, is the main source for Epaminondas's military prowess, and Xenophon describes his admiration for him in his major work Hellenica (book VII, chap. 5, 19). Accordingly, in later centuries the Roman orator Cicero called him "the first man of Greece", and in more recent times Michel de Montaigne judged him one of the three "worthiest and most excellent men" who had ever lived. The changes Epaminondas wrought on the Greek political order did not long outlive him, as the cycle of shifting hegemonies and alliances continued unabated. A mere twenty-seven years after his death, a recalcitrant Thebes was obliterated by Alexander the Great. Thus Epaminondas—who had been praised in his time as an idealist and liberator—is today largely remembered for a decade (371 BC to 362 BC) of campaigning that established a decade long Theban hegemony but also sapped the strength of the great city-states and paved the way for Macedonian hegemony.

The Crypteia, also referred to as Krypteia or Krupteia (Greek: κρυπτεία krupteía from κρυπτός kruptós, "hidden, secret"; members were κρύπται kryptai), was an ancient Spartan state institution. The kryptai either principally sought out and killed helots across Laconia and Messenia as part of a policy of terrorising and intimidating the enslaved population, or they principally did a form of military training, or they principally endured hardships as an initiation ordeal, or the Crypteia served a combination of all these purposes, possibly varying over time. The Krypteia was an element of the Spartan state's child-rearing system for upper-class males.

Modern historians often translate "Krypteia" as "secret police" or "secret service", but its precise structure is debated.

A slave rebellion is an armed uprising by slaves, as a way of fighting for their freedom. Rebellions of slaves have occurred in nearly all societies that practice slavery or have practiced slavery in the past. A desire for freedom and the dream of successful rebellion is often the greatest object of song, art, and culture amongst the enslaved population. These events, however, are often violently opposed and suppressed by slaveholders.

Ancient Sparta had a special type of serf called helots who were often treated harshly, leading them to rebel. According to Herodotus (IX, 28–29), helots were seven times as numerous as Spartans. Every autumn, according to Plutarch (Life of Lycurgus, 28, 3–7), the Spartan ephors would pro forma declare war on the helot population so that any Spartan citizen could kill a helot without fear of blood or guilt in order to keep them in line (crypteia). In the Roman Empire, though the heterogeneous nature of the slave population worked against a strong sense of solidarity, slave revolts did occur and were severely punished. The most famous slave rebellion in Europe was led by Spartacus in Roman Italy, the Third Servile War. This war resulted in the 6,000 surviving rebel slaves being crucified along the main roads leading into Rome. This was the third in a series of unrelated Servile Wars fought by slaves against the Romans.

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 464 BC Spartan earthquake occurred along the Sparta fault in the year 464 BC destroying much of what was Sparta and many other city-states in ancient Greece. Historical sources suggest that the death toll may have been as high as 20,000, although modern scholars suggest that this figure is likely an exaggeration. The earthquake gave Spartan helots an opportunity to revolt against their aristocratic rulers, and the Spartan Pericleidas was sent to the Athenians to seek their aid. Their immediate dismissal upon arrival is said to have been a key event that led up to the First Peloponnesian War.
