Rudrasimha I

Rudrasimha I was a Western Kshatrapa ruler, who reigned from 178 to 197 CE. He was son of Rudradaman I, grandson of Jayadaman, and grand-grandson of Chashtana.

From the reigns of Jivadaman and Rudrasimha I, the date of minting of each coin, reckoned in the Saka era, is usually written on the obverse behind the king's head in Brahmi numerals, allowing for a quite precise datation of the rule of each king. This is a rather uncommon case in Indian numismatics. Some, such as the numismat R.C Senior considered that these dates might correspond to the much earlier Azes era instead.

Rudrasimha I is also known for an inscription in Sanskrit at Gunda, north Kathiawar, mentioning "the digging of a well for the welfare of society by Senapati Bapaka's son, Rudrabhuti Abhira", and dated to Saka era 103 (181 CE). The inscription also gives a detailed genealogy of the kings up to Rudrasimha:

"Hail ! On the [auspicious] fifth tithi of the bright fortnight of Vaisakha during the auspicious period of the constellation of Rohini, in the year one hundred and three — 100 3 — (during the reign) of the king, the Kshatrapa Lord Rudrasiha (Rudrasimha), the son of the king, the Maha-Kshatrapa Lord Rudradaman (and) son’s son of the king, the Kshatrapa Lord Jayadaman, (and) grandson’s son of the king, the Maha-Kshatrapa Lord Chashtana, the well was caused to be dug and embanked by the general (senapati) Rudrabuthi, the sonof the general (senapati) Bapaka, the Abhira, at the village (grama) of Rasopadra, for the welfare and comfort of all living beings."
