7 It is very welknown fact of history that the Gupla Emperor Candragupta-Vikramāditya conquered and ruled over Gujarat defeating the Saka ruler. But it is positively proved here with the help of the literary and archaeological evidences that the Candragupta, the second, had never conquered Gujarat and ruled over it. No epigraphical records have beco found from Gujarat to establish Candragupta's sway over Gujarat. The Guptas ruled over Gujarat only after 415 A.D. And it was Kumārgupta who ruled over Gujarat and none of his predecessors.
8 For the first time the geographical history of the Kshabarātas has been decided in this thesis and also comprehensively discussed the political geography of the Kardamahas alongwith the precise identification of the places mentioned in their inscriptions.
9 Examining the script and the execution of the coins of both Bhūmaka and Nahapāna, a new inference has been derived regarding the proper relationship between them and found that they were related as father and son respectively.
10 Nabapāna has used different royal titles for bimself in his inscriptions. It is clearly proved here that all those different titles are nothing but synonymous.
