TELANGANA SATAVAHANA FOUNDED AT KOTILINGALA

The Sātavāhana was a Telugu dynasty which ruled from Dharanikota or Amaravati in coastal Andhra Pradesh and later from Junnar (Pune), Prathisthan (Paithan) in Maharashtra and Kotilingala (Karimnagar) in Andhra Pradesh over Southern and Central India from around 230 BCE onward. Although there is some controversy about when the dynasty came to an end, the most liberal estimates suggest that it lasted about 450 years, until around 220 CE. The Satavahanas are credited for establishing peace in the country, resisting the onslaught of foreigners after the decline of Mauryan empire.

Next come the Andarae, a still more powerful race, which possesses numerous villages, and thirty towns defended by walls and towers, and which supplies its king with an army of 100,000 infantry, 2,000 cavalry, and 1,000 elephants.

The Sātavāhanas ruled a large and powerful empire that withstood the onslaughts from Central Asia. Aside from their military power, their commercialism and naval activity is evidenced by establishment of Indian colonies in southeast Asia.
