Who was the ruling member of the Sharabhapuriya dynasty in 575 CE?
A. M. Shastri estimates the reigns of the Sharabhapuriya rulers as follows: based on Sharabha's identification with the Sharabharaja mentioned in the 510 CE Eran inscription, he assigns Sharabha's reign to 475���500 CE (assuming a 25-year reign). Similarly, he assigns 25 years to the next two kings. Since Jayaraja's latest inscription is dated to 9th regnal year, Shastri assumes a 10-year reign for Jayaraja, and some subsequent kings.
 
 Sharabha (��arabha), c. 475���500 CE
 Narendra, c. 500���525 CE
 Prasanna, c. 525���550 CE
 Jayar��ja, c. 550���560 CE
 Sudevar��ja, c 560���570 CE
 Manamatra alias Durgar��ja, c. 570���580 CE
 Sudevar��ja, c. 570���580 CE
 Pravar��ja, c. 580���590 CE
 Alternative dates have been proposed by other historians. For example, D. C. Sircar estimated Sharabha's reign as 465���480 CE, while V. V. Mirashi estimated it as 460���480 CE.
Based on that paragraph, the ruler during 575 CE was Sudevar��ja, who ruled from c. 570���580 CE. Note that this may be an estimate, since all of the time periods listed have a "c." (short for "circa"), which indicates some uncertainty about the time ranges listed.
