Tocharians

The Tocharians or Tokharians ( or ) were Indo-European peoples inhabited the medieval oasis city-states on the northern edge of the Tarim Basin (modern Xinjiang, China) in ancient times. Their Tocharian languages, a branch of the Indo-European family, are known from manuscripts from the 6th to 8th centuries AD, after which they were supplanted by the Turkic language of the Uyghur Kingdom of Qocho who invaded Tarim Basin. These people were called "Tocharian" by late-19th century scholars who identified them with the Tókharoi described by ancient Greek sources as inhabiting Bactria. Although this identification is now generally considered mistaken, the name has become customary.

Some scholars have linked the Tocharians with the Afanasevo culture of eastern Siberia (c. 3500 – 2500 BC), the Tarim mummies (c. 1800 BC) and the Yuezhi of Chinese records, most of whom migrated from western Gansu to Bactria in the 2nd century BC and then later to the northwestern Indian subcontinent where they founded the Kushan Empire.
