Slavery, Prosperity, and Inequality in Roman Pompeii

Abstract Historians of premodern economies, in contrast to modern ones, have only infrequently contemplated the economic contribution of slavery. Here, I suggest that quantitative and statistical tools allow us to evaluate the place of slavery in an early economy, using Roman Pompeii as a case study. At the time of its destruction in 79 ce, Pompeii appears prosperous, having benefitted from the economic development thought to have characterized the Roman world. Recent discoveries, meanwhile, shed new light on the conditions of working classes and slaves throughout the city. These narratives can be seen to form two sides to the same coin, as Pompeii’s prosperity was created in large part thanks to slave labour. The connection is supported by constructing a probabilistic model, which suggests some 6 million sesterces (HS) flowed every year to Pompeii’s masters through their exploitation of slaves. Slave owning probably formed the largest single income source for the urban economy. This scale of income is shown to be consistent with recent reconstructions of wealth and income inequality in the city. The results not only speak to slavery’s profound importance to Pompeii’s prosperity, but they encourage a recentring of labour and slavery in Roman economic history.
