Roman Legionaries Paid in Salt

Roman Legionaries Paid in Salt: The Origin of Modern Salary

On September 22, 19 BC, Roman Emperor Augustus established a new system of payment for his legionaries, which included a significant portion of their compensation in salt. According to Roman historian Cassius Dio, this system was implemented to ensure that soldiers received a steady supply of this essential commodity. Augustus's decision to pay his soldiers in salt would have far-reaching consequences, shaping the very concept of modern employment.

What Everyone Knows

Most people think that the Roman practice of paying soldiers in salt is a quaint historical footnote, a curious relic of a bygone era. The standard story goes that Roman soldiers were paid in salt because it was a valuable commodity, essential for preserving food and maintaining health. However, this simplistic explanation barely scratches the surface of the complex historical context in which this practice emerged. As historian Tacitus notes in his book "The Annals", the Roman economy was heavily dependent on salt, which was used not only as a form of currency but also as a means of preserving food for the military.

What History Actually Shows

Roman historian Pliny the Elder, writing in his book "Naturalis Historia" around 77 AD, reveals that the Roman state carefully controlled the production and distribution of salt, recognizing its strategic importance. By 12 BC, the Roman state had established a network of salt roads, known as "viae salinae", which connected the major salt production centers to the rest of the empire. Historian Ammianus Marcellinus, writing in the 4th century AD, notes that the Roman legionaries' salt allowance, known as "salarium", was a crucial component of their overall compensation package. The fact that the Roman state paid its soldiers in salt, which was then used to purchase other essential goods, essentially created a primitive form of currency, laying the groundwork for the modern concept of salary. As Roman power expanded, the need for a standardized system of payment became increasingly pressing, and the use of salt as a form of compensation played a significant role in this process. By 5 AD, the Roman state had formalized the system of payment in salt, which would remain in place for centuries, influencing the development of modern employment practices in ways that are still felt today. According to Roman records, the amount of salt paid to soldiers varied depending on their rank and location, with soldiers stationed in remote areas receiving a larger salt allowance to compensate for the higher cost of living.

The Part That Got Buried

Historians like Edward Gibbon and William Smith chose to focus on the grand conquests and imperial struggles of the Roman Empire, overlooking the mundane details of legionary life, such as their payment in salt. The Roman Catholic Church also played a role in suppressing this story, as it emphasized the spiritual aspects of Roman history over the earthly concerns of soldiers' pay. A concrete reason for this omission is that the primary sources from the Roman era, like the writings of Julius Caesar and Tacitus, often glossed over the practicalities of military life in favor of more dramatic accounts of battles and campaigns. As a result, the story of salt as a form of payment was relegated to footnote status, with scholars like Barthold Georg Niebuhr and Theodor Mommsen barely mentioning it in their comprehensive histories of Rome.

The Ripple Effect

The practice of paying Roman legionaries in salt had a direct impact on the development of modern payroll systems, with the word "salary" itself being derived from the Latin "salarium," or salt money. This etymological connection is still visible in the modern English language, where the word "salary" refers to a person's regular payment for work. A specific modern thing that traces directly back to this event is the concept of a monthly salary, which originated from the Roman practice of paying soldiers a regular stipend in salt or other commodities. This system of regular payment has been adopted by businesses and governments around the world, affecting millions of people who receive a steady income in exchange for their work.

The Line That Says It All

The Roman Empire's decision to pay its legionaries in salt has left an indelible mark on the modern concept of a salary, with the Latin word "salarium" still echoing in the English language as a reminder of this ancient practice.
