68 in Bactria and the departure of the Sacae for India a chief of the Kushans, one of the tribes of the Yüeh-chi, gained supremacy over the entire group (about  25–81?) and established a kingdom which became known by the name of his tribe. This king, Kujula Kadphises, rapidly expanded his power over Gandhara, Arachosia, and Kabul at the expense of either Gondopharnes or Pacores. Perhaps the Parthian conquests to which the Chinese sources refer are those of the Kushans in the Indo-Scythian kingdoms; possibly they may indicate attacks on Parthia proper. The second of the Kushan rulers, V'ima Kadphises, ended his reign not long before the accession of Kanishka, whose date has been so long a subject of discussion ( 125?).
