クジュラ・カドフィセス
In the 1st century BC, the "Guishuang" (Ch: 貴霜) gained prominence over the other Yuezhi tribes, and welded them into a tight confederation under "yabgu" (Commander) Kujula Kadphises. The name "Guishuang" was adopted in the West and modified into "Kushan" to designate the confederation, although the Chinese continued to call them "Yuezhi".
