Maurya empire and Satavahana dynasty

The Maurya Empire was a geographically extensive Iron Age historical power in South Asia with its power base in Magadha. Founded by Chandragupta Maurya around c. 320 BCE, it existed in loose-knit fashion until 185 BCE. The primary sources for the written records of the Mauryan times are partial records of the lost history of Megasthenes in Roman texts of several centuries later, and the Edicts of Ashoka. Archaeologically, the period of Mauryan rule in South Asia falls into the era of Northern Black Polished Ware (NBPW).

The Satavahanas (; Sādavāhana or Sātavāhana, IAST: Sātavāhana), also referred to as the Andhras (also Andhra-bhṛtyas or Andhra-jatiyas) in the Puranas, were an ancient Indian dynasty. Most modern scholars believe that the Satavahana rule began in the late 2nd century BCE and lasted until the early 3rd century CE, although some assign the beginning of their rule to as early as the 3rd century BCE based on the Puranas, but uncorroborated by archaeological evidence. The Satavahana kingdom mainly comprised the present-day Andhra Pradesh, Telangana, and Maharashtra. At different times, their rule extended to parts of modern Gujarat, Madhya Pradesh, and Karnataka. The dynasty had different capital cities at different times, including Pratishthana (Paithan) and Amaravati (Dharanikota).
