of Indo-European speakers such as the Tocharians and Saka people. Jade from Khotan had been traded into China for a long time before the founding of the city, as indicated by items made of jade from Khotan found in tombs from the Shang (Yin) and Zhou dynasties. The jade trade is thought to have been facilitated by the Yuezhi. Foundation legend There are four versions of the legend of the founding of Khotan. These may be found in accounts given by the Chinese pilgrim Xuanzang and in Tibetan translations of Khotanese documents. All four versions suggest that the city was founded around the third century BC by a group of Indians during the reign of Ashoka. According to one version, the nobles of a tribe in ancient Taxila, who traced their ancestry to the deity Vaiśravaṇa, were said to have blinded Kunãla, a son of Ashoka. In punishment they were banished by the Mauryan emperor to the north of the Himalayas, where they settled in Khotan and elected one of their members as king. However war then ensued with another group from China whose leader then took over as king, and the two colonies merged. In a different version, it was Kunãla himself who was exiled and founded Khotan. The legend suggests that Khotan was settled by people from northwest India and China, and may explain the division of Khotan into an eastern and western city since the Han dynasty. Others however argued that the legend of the founding of Khotan is a fiction as it ignores the Iranian population, and that its purpose was to explain the Indian and Chinese influences that were present in Khotan in the 7th century AD. By Xuanzang's account, it was believed that the royal power had been transmitted unbroken since the founding of Khotan, and evidence indicates that the kings of Khotan had used an Iranian-based word as their title since at least the 3rd century AD, suggesting that they may be speakers of an Iranian language. In the 1900s, Aurel Stein discovered Prakrit documents written in Kharoṣṭhī in Niya, and together with the founding legend of Khotan, Stein proposed that these people in the Tarim Basin were Indian immigrants from Taxila who conquered and colonized Khotan. The use of Prakrit however may be a legacy of the influence of the Kushan Empire. There were also Greek influences in early Khotan, based on
