Asii

The Asii, Osii, Ossii, Asoi, Asioi, Asini or Aseni were an ancient Indo-European of Central Asia, during the 2nd and 1st Centuries BCE. Known only from Classical Greek and Roman sources, they were one of the peoples held to be responsible for the downfall of the Greco-Bactrian Kingdom.

Modern scholars have attempted to identify the Asii with other peoples known from European and Chinese sources including the: Yuezhi, Tocharians, Issedones/ Wusun and/or Alans.
