A prisoner of war (POW) is a person who is held captive by a belligerent power during or immediately after an armed conflict. The earliest recorded usage of the phrase "prisoner of war" dates back to 1610. Belligerents hold prisoners of war in custody for a range of legitimate and illegitimate reasons, such as isolating them from the enemy combatants still in the field (releasing and repatriating them in an orderly manner after hostilities), demonstrating military victory, punishing them, prosecuting them for war crimes, exploiting them for their labour, recruiting or even conscripting them as their own combatants, collecting military and political intelligence from them, or indoctrinating them in new political or religious beliefs. Ancient times For most of human history, depending on the culture of the victors, enemy fighters on the losing side in a battle who had surrendered and been taken as prisoners of war could expect to be either slaughtered or enslaved. Early Roman gladiators could be prisoners of war, categorised according to their ethnic roots as Samnites, Thracians, and Gauls (Galli). Homer's Iliad describes Greek and Trojan soldiers offering rewards of wealth to opposing forces who have defeated them on the battlefield in exchange for mercy, but their offers are not always accepted; see Lycaon for example. Typically, victors made little distinction between enemy combatants and enemy civilians, although they were more likely to spare women and children. Sometimes the purpose of a battle, if not of a war, was to capture women, a practice known as raptio; the Rape of the Sabines involved, according to tradition, a large mass-abduction by the founders of Rome. Typically women had no rights, and were held legally as chattels. In the fourth century AD, Bishop Acacius of Amida, touched by the plight of Persian prisoners captured in a recent war with the Roman Empire, who were held in his town under appalling conditions and destined for a life of slavery, took the initiative in ransoming them by selling his church's precious gold and silver vessels and letting them return to their country. For this he was eventually canonized. Middle Ages and Renaissance According to legend, during Childeric's siege and blockade of Paris in 464 the nun Geneviève (later canonised as the city's patron saint) pleaded with the Frankish king for the welfare of prisoners of war and met with a favourable response. Later, Clovis I () liberated captives after
