"The Rabatak inscription claims that in the year 1 Kanishka I's authority was proclaimed in India, in all the satrapies and in different cities like Koonadeano (Kundina), Ozeno (Ujjain), Kozambo (Kausambi), Zagedo (Saketa), Palabotro (Pataliputra) and Ziri-Tambo (Janjgir-Champa). These cities lay to the east and south of Mathura, up to which locality Wima had already carried his victorious arm. Therefore they must have been captured or subdued by Kanishka I himself." "Ancient Indian Inscriptions", S. R. Goyal, p. 93. See also the analysis of Sims-Williams and J.Cribb, who had a central role in the decipherment: "A new Bactrian inscription of Kanishka the Great", in "Silk Road Art and Archaeology" No4, 1995–1996.

(२००७), The history of Afghanistan, Westport: Greenwood Press, पृ:४६, आइएसबिएन9780313337987, "The Yuezhi people conquered Bactria in the second century B.C.E. and divided the country into five chiefdoms, one of which would become the Kushan Empire. Recognizing the importance of unification, these five tribes combined under the one dominate Kushan tribe, and the primary rulers descended from the Yuezhi."
