have been found in eastern Madhya Pradesh. However, Andrew Ollett argues that there is only one Satakarni, as the alleged first Satakarni is assigned ten years, and the second, fifty years by other scholars, but the only dated inscription of this king is Candankheda seal from his reign's year 30, around 60 BCE, and he ruled ca. 88-42 BCE. Art of Sanchi The Satavahanas contributed greatly to the embellishment of the Buddhist stupa of Sanchi. It was heavily repaired under King Satakarni II. The gateways and the balustrade were built after 70 BCE, and appear to have been commissioned by the Satavahanas. An inscription on the Southern Gateway records that it was the work of Satakarni II's royal architect Ananda. An inscription records the gift of one of the top architraves of the Southern Gateway by the artisans of the Satavahana Emperor Satakarni: First Western Satraps invasion under Nahapana Little is known about Apilaka's successors, except cryptic references to one Kuntala Satakarni. The next well-known ruler of the dynasty was Hāla, who composed Gaha Sattasai in Maharashtri Prakrit. Like Hala, his four successors also ruled for very short periods (a total of 12 years), indicating troubled times for the Satavahanas. Epigraphic and numismatic evidence suggests that the Satavahanas earlier controlled the northern Deccan Plateau, the northern Konkan coastal plains, and the mountain passes connecting these two regions. During 15-40 CE, their northern neighbours - the Western Kshatrapas - extended their influence into these regions. The Western Kshatrapa ruler Nahapana is known to have ruled the former Satavahana territory, as attested by the inscriptions of his governor and son-in-law, Rishabhadatta. First revival The Satavahana power was revived by Gautamiputra Satakarni, who is considered the greatest of the Satavahana rulers. Charles Higham dates his reign . S. Nagaraju dates it 106–130 CE, the new consensus is shared by Shailendra Bhandare, Akira Shimada, and Oskar von Hinuber, who regard Gautamiputra Satakarni's reign was ca. 60-85 CE, as it is evident from history that "Gautamiputra Saatakarni" in the year 78CE defeated Vikramaditya of Ujjain, which in turn was celebrated and named "Yug Aadi" means Beginning of New Era (New Year for Andhra, Karnataka, Maharashtra (Gudi padwa), Telangana states). Ever since these states people followed Saatavaahana calendar. Andrew Ollett considers it as 60-84 CE. The king defeated by him appears to have been the Western Kshatrapa ruler Nahapana, as suggested by Nahapana's coins overstuck with
