Analysis of information sources in references of the Wikipedia article "Satavahana dynasty" in English language version.
The Sätavahanas are said to be supporters of Mahayana Buddhism and Brahmanism. A.K. Warder says that Mahāyānism was most prosperous and many stupas, monasteries and caves were built in the Sätavahana empire.
The use of Prakrit in Ashokan inscriptions and its continuance under the Satavahanas as the official language raised Maharashtri Prakrit from a common local dialect to the stature of a literary idiom. The most important work is Satasati or Gathasaptasati-an anthology of 700 erotic verses in Maharashtri Prakrit and in the Arya metre. Gunadhya's Brihatkatha (Great Romance) probably belonged to this period.
Arguments are put forth trying to prove differently that they were Sudras, Kshatriyas and Brahmins.
An inscription from Sthanakundür and coins with images of Skanda and bull, issued by Siri Satakani indicate that the early Satavahanas were devotees of Siva. Though, the early Satavāhana rulers were staunch devotees of Saivism, their religious edifices have not been traced so far in coastal Andhra Desa.
