Mention by Panini
Simuka's successor Sātakarnī I was the sixth ruler of the Satavahana. He is said in the Puranas to have ruled for 56 years. Satakarni defeated the Sunga dynasty of North India by wrestling Western Malwa from them, and performed several Vedic sacrifices at huge cost, including the Horse Sacrifice. He also was in conflict with the Kalinga ruler Kharavela, who mentions him in the Hathigumpha inscription. According to the Yuga Purana he conquered Kalinga following the death of Kharavela. He extended Satavahana rule over Madhya Pradesh and pushed back the Sakas from Pataliputra (he is thought to be the Yuga Purana's "Shata", an abbreviation of the full name “Shri Sata” that occurs on coins from Ujjain), where he subsequently ruled for 10 years.
