The same inscription further mentions that the stúpa was given while the Kshatrapa Sudása son of the Mahákshatrapa Rájavula was ruling at Mathurá. The inference from the difference in the titles of the father and the son seems to be that Sudása was ruling in Mathurá as governor under his father who perhaps ruled in the neighbourhood of Delhi where many of his coins have been found. While the coins of Sudása have the legend in Nágarí only, Rájavula's coins are of two varieties, one with the legend in Baktro-Páli and the other with the legend in Nágarí, a fact tending to show that the father's territories stretched to the far north. Though Kharaosti is mentioned as a Yuvarája or prince heir-apparent in the time of his maternal uncle Sudása, the inscription shows he had four children. It is curious that while the inscription mentions Nandasiriká as the mother of Kharaosti Yuvarája, nothing is said about her husband. Perhaps he was dead or something had happened to make Nandasiriká live at her father's home. [Western Kshatrapas, A.D. 70-398.] Another inscription of Sudása found by General Cunningham at Mathurá is in old Nágarí character. Except that they have the distinctive and long continued Kshatrapa peculiarity of joining ya with other letters the characters of this inscription are of the same period as those of the inscriptions of the great Indo-Skythian or Kushán king Kanishka. This would seem to show that the conquest of Mathurá by Kanishka took place soon after the time of Kshatrapa Sudása. It therefore appears probable that Nahapána, the first Kshatrapa ruler of Gujarát and Káthiáváda, the letters of whose inscriptions are of exactly the same Kshatrapa type as those of Sudása, was a scion of the Kharaosti family, who, in this overthrow of kingdoms, went westwards conquering either on his own account or as a general sent by Kanishka. Nahapána's [65] advance seems to have lain through East Rájputána by Mandasor [66] in West Málwa along the easy route to Dohad as far as South Gujarát. From South Gujarát his power spread in two directions, by sea to Káthiáváda and from near Balsár by the Dáng passes to Násik and the Deccan, over almost the whole of which, judging from coins and inscriptions, he supplanted as overlord the great Ándhra kings of the Deccan. No evidence is available to show either that East Málwa with its capital at Ujjain or that North Gujarát formed part of his dominions. All the information we have regarding Nahapána is from his own silver coins and from the inscriptions of his son-in-law Ushavadáta at Násik and Kárle and of his minister Ayáma (Sk. Áryaman) at Junnar. Nahapána's coins are comparatively rare. The only published specimen is one obtained by Mr. Justice Newton. [67] Four others were also obtained by Dr. Bhagvánlál from Káthiáváda and Násik.
