Did Chinese prisoners at the Battle of Talas really bring papermaking west?

Probably not, or at least not in the simple way the story says. A well-known account holds that Chinese prisoners captured at the Battle of Talas in 751 introduced papermaking to West Asia, but that account is disputed by several findings. It is recorded by the 11th-century historian al-Tha'alibi, who wrote that the prisoners introduced paper manufacturing to Samarkand. Yet the account is unlikely to be factual: paper was already in use throughout Central Asia by the 8th century, with fragments from the 4th and 5th centuries found at Turpan and Gaochang.

There are other reasons for doubt. No historic Chinese source records this transfer of technology through prisoners, and no contemporary Arabic accounts of it exist. A Chinese prisoner, Du Huan, who returned home, listed weavers, painters, goldsmiths and silversmiths among those taken, but no papermakers. According to the scholar Jonathan Bloom, paper was used in Samarkand, and probably produced there, several decades before the battle.

The story is useful as a symbol rather than a fact. The real journey of paper west was slower and moved along the Silk Road. First documented in China in the Han period, it reached Samarkand by 751, Baghdad by 793 and Egypt by 900, and by the 11th century it had reached Europe. The battle is real, but the neat explanation attached to it is not what the evidence shows.
