The Extent of Slavery
Chattel slavery became widespread in Greece only after about 600 B.C. Eventually,
slaves became cheap enough that
people of moderate means could afford one or
two1. Nevertheless, even wealthy Greek landowners never acquired gangs of hundreds of
slaves like those who maintained Rome's water system under the Roman Empire or worked
large plantations in the southern United States before the American Civil War.
Maintaining a large number of slaves year around in ancient Greece would have been
uneconomical because the cultivation of the crops grown there called for short periods
of intense labor punctuated by long stretches of inactivity, during which slaves would
have to be fed even while they had no work to do.
By the fifth century B.C., however, the number of slaves in some city-states had grown
to as much as one-third of the total population. This percentage still means that most
labor was performed by small land-owners and their families themselves, sometimes hiring
free workers. The special system of
slavery in Sparta2 provides a rare exception to this situation.
