In his Institutiones (161 AD), the Roman jurist Gaius wrote that:

Slavery is a human invention and not found in nature. Indeed, it was that other human invention, war, which provided the bulk of slaves, but they were also the bounty of piracy ... or the product of breeding. —Gaius, as translated and quoted by Nic Fields

The 1st-century BC Greek historian Dionysius of Halicarnassus indicates that the Roman institution of slavery began with the legendary founder Romulus giving Roman fathers the right to sell their own children into slavery, and kept growing with the expansion of the Roman state. Slave ownership was most widespread throughout the Roman citizenry from the Second Punic War (218–201 BC) to the 4th century AD. The Greek geographer Strabo (1st century AD) records how an enormous slave trade resulted from the collapse of the Seleucid Empire (100–63 BC).

The Twelve Tables, Rome's oldest legal code, have brief references to slavery, indicating that the institution was of long standing. In the tripartite division of law by the jurist Ulpian (2nd century AD), slavery was an aspect of the ius gentium, the customary international law held in common among all peoples (gentes). The "law of nations" was neither natural law, which existed in nature and governed animals as well as humans, nor civil law, which was the body of laws specific to a people. All human beings are born free (liberi) under natural law, but slavery was held to be a practice common to all nations, who might then have specific civil laws pertaining to slaves. In ancient warfare, the victor had the right under the ius gentium to enslave a defeated population; however, if a settlement had been reached through diplomatic negotiations or formal surrender, the people were by custom to be spared violence and enslavement. The ius gentium was not a legal code, and any force it had depended on "reasoned compliance with standards of international conduct."
