The best-known Chalukya ruler was Pulakeshin II. We know about him from a prashasti, composed by his court poet Ravikirti. This tells us about his ancestors, who are traced back through four generations from father to son. Pulakeshin evidently got the kingdom from his uncle. According to Ravikirti, he led expeditions along both the west and the east coasts. Besides, he checked the advance of Harsha.
