The evolution of captives from property to protected human beings

In short: In the early days of warfare, a captured soldier was often viewed as mere chattel—movable property to be enslaved or sold. It took centuries of legal philosophy and bloody conflict to establish the modern principle that prisoners are humans to be quarantined from combat, not discarded by the victor.

The treatment of captives has undergone a radical transformation in Western history. In early warfare, defeated enemies were frequently killed or enslaved, with women, children, and elders often disposed of as spoils. It was only during the time of Julius Caesar that certain captives might potentially become freedmen within the Roman Empire. During the Middle Ages, while enslavement declined, ransoming became a common practice.

The shift toward modern protections began in the 17th century. Philosophers like Hugo Grotius argued for exchange and ransom over enslavement in his 1625 work 'De jure belli ac pacis'. The era of mass enslavement concluded following the Treaty of Westphalia (1648), a landmark agreement that mandated freeing captives without requiring ransom. By the 18th century, Montesquieu proposed that a captor's only right was to prevent a prisoner from doing harm, moving the status of the captive from 'property' to someone merely removed from the fight.

Despite these philosophical shifts, observance remained inconsistent. The American Civil War (1861–1865) saw horrific conditions at Camp Sumter in Andersonville, Georgia. There, approximately 45,000 Union prisoners were held in a space so overcrowded that nearly 13,000—about 28%—died from scurvy, diarrhea, and dysentery. It took further international conferences in 1874, 1899, and 1907 to formalize rules of conduct, eventually leading to the Geneva Conventions which sought to ensure prisoners were humanely treated without loss of citizenship.

The consequences of failing these standards remain stark. During World War II, while some nations maintained Hague and Geneva standards, others engaged in genocidal severity. Approximately 2,000,000 out of roughly 5,700,000 Red Army troops seized by Germany lived; numerous others perished from hunger alone.
