What was slavery like in ancient Greece?

During war, victorious Greek armies often enslaved captured civilians, especially women and children.

After the Athenian siege of Melos in 416 BCE, for instance, they executed the male defenders and sold the rest of the population.

Similar practices often occurred in other campaigns, though large-scale enslavements like those at Melos were less consistently documented.

For example, Athens lost Amphipolis in 422 BCE, but primary sources do not confirm the mass enslavement of the city's population.

As campaigns advanced, commanders acquired people who became war spoils, which merchants then sold in markets across the Aegean.

By the 2nd century BCE, Delos had developed into a major slave market, where traders likely moved thousands of people each year with little oversight.

According to Strabo, as many as 10,000 slaves could be sold in a single day at Delos, though this number likely reflects an overstatement used for effect rather than an exact headcount.

Occasionally, pirates raided towns near the Black Sea or eastern Aegean, and they captured individuals who were then sold to buyers in Ephesus, Rhodes, or Corinth.

Their victims ranged from isolated villagers to wealthy merchants, and slave traders often separated families before they transported them south.

In many cases, captives never returned to their homelands, since owners cared more about their labour potential than about their personal identity. 

Earlier in the Archaic period, debt bondage had also helped to increase the use of slavery.

Before 594 BCE, some Athenian citizens who had failed to repay loans faced enslavement, which often led to exile or sale abroad.

After Solon had introduced his reforms, particularly the seisachtheia laws, the practice ended for citizens, and non-Greeks and those born to enslaved mothers still stayed vulnerable.

By law, a child inherited the status of its mother, regardless of who fathered it.

Across cities and rural estates, slaves performed labour that supported both private households and public projects and services.

In wealthier homes, domestic slaves were known as oiketai, and they cleaned, cooked, carried water, watched children, and attended their masters in daily rituals.

Some developed trusted positions, such as the role of paidagogos, in which they accompanied boys to school and supervised behaviour.

The banker Pasion began life as a slave and earned manumission and eventually citizenship due to his exceptional service in such roles.

However, owners retained full authority, and even trusted slaves could be sold, punished, or separated from their families at short notice.

On agricultural estates, slaves generally lived under harsher conditions. Many worked outdoors from sunrise to sunset, and they managed olive groves and vineyards, and they also carried out additional labour in the grain fields under the direction of overseers.

Their output fed urban centres and generated wealth for absentee landlords, who relied on their forced labour but rarely interacted with them.

After harvests, owners might lease surplus slaves to neighbours or shift them to construction projects.

Within cities, workshop slaves operated as artisans, metalworkers, shoemakers, and potters.

Skilled slaves often increased the wealth of their masters by producing goods for sale, and in some cases, they paid a portion of their earnings to buy limited independence.

Some accumulated savings over time, known in Roman terms as a peculium, which allowed them to negotiate manumission, though only if their owner agreed.

While this arrangement lacked legal protection in Greek law, informal recognition gave them a limited degree of economic independence.

Athenian citizens such as Nicias leased hundreds of slaves to the state-run mines at Laurion, where workers endured cramped shafts filled with poisonous gases and faced frequent collapses. Many probably never left the mines alive. 

In Sparta, the helot system created a separate class of unfree labourers drawn mainly from conquered Messenian populations.

Unlike chattel slaves, helots belonged to the state, not individuals, and worked the land and supplied a portion of their harvest to Spartan citizens.

Estimates suggest that helots may have outnumbered citizens by as many as seven to one, and this situation created constant anxiety among the ruling elite.

The ruling class often enforced obedience through public humiliation in special ceremonies and random violence.

As part of their military training, young Spartans participated in the krypteia, where they patrolled the countryside and killed suspected troublemakers among the helot population.

Following a major earthquake in 464 BCE, helots revolted, and the Spartans responded with severe crackdowns to prevent further uprisings.

Under Greek law, slaves held no rights as individuals. They could not marry legally, own property, enter contracts, or speak in court without being tortured first.

Athenian legal procedure set out this practice clearly in law, and it required torture for any slave testimony admitted in court.

Owners had full control and could impose punishments, extract confessions, or sell slaves at will.

However, Athenian law penalised the murder of slaves in order to maintain public order rather than to protect the victim.

Occasionally, owners freed loyal or skilled slaves by symbolic sale to a god at a sanctuary.

At Delphi, for example, manumission inscriptions recorded such transactions, which granted limited freedom under religious protection.

One such inscription was IG VII 409, and it details the manumission of a female slave who had to continue working for her former master during specific festivals.

Freed individuals often agreed to continue working for their former masters for a set number of years or during festivals, and many stayed socially tied to them long after.

Even after manumission, few freed slaves became citizens. Most joined the class of metics, resident foreigners who paid taxes and could trade legally but had no access to political rights.

In Classical Athens, the number of metics may have exceeded 10,000. Some established small businesses or worked as agents of their former owners, especially in trades that required trusted contacts or specialised knowledge.

Among Greek intellectuals, few questioned the existence of slavery, though some discussed its moral basis.

In Politics, Aristotle argued that slavery benefited those "born to be ruled," especially non-Greeks whom he described as lacking the rational capacity for self-governance.

He wrote that "from the hour of their birth, some are marked out for subjection, others for rule," claiming that natural inequality made slavery necessary and beneficial, provided the master exercised authority with moderation.

By contrast, dramatists such as Euripides sometimes used slave characters to show the double standards or cruelty of their masters.

In tragedies, slaves occasionally offered the most reasoned observations, while comedies featured clever servants who mocked authority and reversed expectations.

Even so, those portrayals stayed fictional, and real-world slaves continued to live under severe restrictions.

Across the Greek world, economic life and political power largely relied on unfree labour.

Public works, such as road building and temple maintenance, together with large-scale naval operations, regularly used slaves who were owned by the state.

In Athens, public slaves who were known as dēmosioi included scribes, clerks, mint workers, and Scythian Archers who policed the city.

Households often depended on them for daily survival, and the elite also valued them as status symbols.

Religious festivals included roles for sacred slaves who performed temple duties, sang hymns, or carried ceremonial objects.

The average cost of a slave in Classical Athens ranged from 200 to 300 drachmas, and prices rose according to age, skill, or physical condition.
