[6] The Nashik prashasti inscription of Gautamiputra's mother Gautami Balashri, dated to the 20th year after his death, records his achievements.

The Nashik inscription dated to the 18th year of Gautamiputra's reign states that he reaffirmed a grant of land to Buddhist monks living at the Triraśmi peak.

3 of the Pandavleni Caves in Nashik: Gautamiputra Satakarni (…) who crushed down the pride and conceit of the Kshatriyas; who destroyed the Sakas (Western Satraps), Yavanas (Indo-Greeks) and Pahlavas (Indo-Parthians),[13] who rooted out the Khakharata family (the Kshaharata family of Nahapana); who restored the glory of the Satavahana race.A satrap named Chastana founded the Kardamaka dynasty after Nahapana's death.

The inscription relating the marriage between Rudradaman's daughter and Vashishtiputra Satakarni appears in a cave at Kanheri: Of the queen ... of the illustrious Satakarni Vasishthiputra, descended from the race of Karddamaka kings, (and) daughter of the Mahakshatrapa Ru(dra)....... .........of the confidential minister Sateraka, a water-cistern, the meritorious gift.The Satavahanas and the Western Satraps remained at war however, and Rudradaman I defeated the Satavahanas twice in these conflicts, only sparing the life of Vashishtiputra Satakarni due to their family alliance: Rudradaman (...) who obtained good report because he, in spite of having twice in fair fight completely defeated Satakarni, the lord of Dakshinapatha, on account of the nearness of their connection did not destroy him.Rudradaman regained all the previous territories held by Nahapana, probably with the exception of the southern areas of Poona and Nasik (epigraphical remains in these two areas at that time are exclusively Satavahana):[16] In later years, Yajna Sri Satakarni of the Šātavāhana dynasty emerged as a formidable figure, extending his influence over the southern territories of the Western Satraps.

However, following his demise, the vast realm underwent fragmentation, giving rise to numerous independent principalities, likely still under the sway of the Šātavāhana legacy.
