In addition to this, modern study of monuments and inscriptions has recovered the names, and to a certain extent the records, of a succession of dynasties ruling in the Deccan; of these the most conspicuous are the Cholas, the Andhras or Satavahanas, the Chalukyas, the Rashtrakutas and the Yadavas of Devagiri (Deogiri).
Until about 27 B.C., when it was overthrown by an unknown king of the Andhra dynasty of the Satavahanas, whose power, originating in the deltas of the Godavari and Kistna rivers, by A.D.
Bombay originally consisted of seven islands (the Heptanesia of Ptolemy) and formed an outlying portion of the dominions of successive dynasties dominant in western India: Satavahanas, Mauryas, Chalukyas and Rashtrakutas.
On the death of Asoka in 231 B.C. the empire of the Mauryas broke up, and their heritage in the west fell to the Andhra dynasty of the Satavahanas of Paithan on the Godavari, a Dravidian family whose dominion by 200 B.C. stretched across the peninsula from the deltas of the Godavari and Kistna to Nasik and the Western Ghats.
40 the coast cities had been much enriched by trade with the Roman empire, which both the Satavahanas and the satraps did much to encourage; but after the fall of Palmyra (273) and the extinction of the main Kshaharata dynasty (c. 300) this commerce fell into decay.
