times, once between Saka Era 100 and 103 (178-181 CE), before the rule of Rudrasimha I, and once between Saka Era 119 and 120 (197-198 CE). Rudrasimha I (180-197) [[File:Western Satrap Coin of Rudrasimha I .jpg|thumb|250px|Coin of the Western Kshatrapa ruler Rudrasimha I (178–197). Obv: Bust of Rudrasimha, with corrupted Greek legend "..OHIIOIH.." (Indo-Greek style). Rev: Three-arched hill or Chaitya, with river, crescent and sun, within Prakrit legend in Brahmi script: An inscription of Rudrasimha I (178-197) was recently found at Setkhedi in Shajapur district, dated to 107 Saka Era, that is 185 CE, confirming the expansion of the Western Satraps to the east at that date. There is also an earlier inscription related to Saka rule in Ujjain, as well as a later one, the Kanakerha inscription, related to Saka rule in the area of Vidisha, Sanchi and Eran in the early 4th century. Great Satrap Rupiamma (2nd century CE) A memorial pillar with an inscription in the name of "Mahakshatrapa Kumara Rupiamma" has been recovered in Pauni in the central region of Vidharba, and is dated to the 2nd century CE. Although this Great Satrap is not otherwise known from coinage, this memorial pillar is thought to mark the southern extent of the conquests of the Western Satraps, much beyond the traditionally held boundary of the Narmada River. The use of the word "Kumara" may also mean that Rupiamma was the son of a Great Satrap, rather than holding the title himself. Loss of southern territories to the Satavahanas (end of 2nd century CE) The south Indian ruler Yajna Sri Satakarni (170-199 CE) of the Satavahana dynasty defeated the Western Satraps in the late 2nd century CE, thereby reconquering their southern regions in western and central India, which led to the decline of the Western Satraps. Yajna Sri Satakarni left inscriptions in Nasik Caves, Kanheri and Guntur, testifying to the renewed extent of Satavahana territory. There are two inscriptions of Yajna Sri Satakarni at Kanheri, in cave No. 81, and in the Chaitya cave No. 3. In the Nasik Caves, there is one inscription of Sri Yajna Satakarni, in the 7th year of his reign. There is a possibility, however, that the areas of Poona and Nasik had remained in the hands of the Satavahanas since the time of Gautamiputra Satakarni after his victory over Nahapana, as there are no epigraphical records of the Kardamakas in this area.
