Deportation was an institutionalised instrument of Hittite statecraft from the Old Kingdom to the collapse of the empire around 1180 BCE. The Telipinu Proclamation records that Mursili I carried the deportees and goods of Aleppo, and then of Babylon, back to Hattusa; the annals of Suppiluliuma I and Mursili II record the transfer of populations from Arzawa and other western Anatolian lands to the Hittite core. Transportees were designated NAM.RA / arnuwala-, a defined legal status rather than simple captivity, and were assigned to royal and temple estates, to depopulated farmland and to military settlements, with their labour serving to repair the chronic manpower shortage of the Hittite heartland. The numbers survive only in royal campaign narratives written to display the king's success; scholars accept the practice as systematic and large-scale while treating the specific totals, especially those above ten thousand, as unverifiable.
Hittite kings from Hattusili I and Mursili I to Suppiluliuma I and Mursili II moved captured civilian populations from Syria, Anatolia and the Aegean fringe to the Hittite homeland as agricultural and temple labour
Hittite royal annals record captives, the NAM.RA, by campaign rather than by population: Mursili II's ten-year annals alone claim tens of thousands from single campaigns, and Bronze Age Hatti's own population is guessed at roughly one to two million from settlement survey. There is no register, tax list or archaeological base from which the population of the conquered territories over 1600-1180 BCE could be reconstructed, so any percentage would be invented.
No death toll can be given. Hittite annals describe the destruction of towns and the killing of defenders but were principally concerned with the living population carried off, whose value lay in their labour; mortality in transit is not recorded.
The assignment of NAM.RA transportees to royal, temple and agricultural labour is documented in the Hittite royal annals and summarised in the general literature on the Hittites.
