Bindusara Maurya (r. c. 320–273 BCE) was the second emperor of the Maurya Empire. During his reign, the empire expanded southwards. He had two well-known sons, Susima and Ashoka, who were the viceroys of Taxila and Ujjain, respectively. The Greeks called him Amitrochates or Allitrochades – the Greek transliteration for the Sanskrit word Amitraghata "Slayer of enemies". He was also called Ajatashatru "Man with no enemies" in Sanskrit (not to be confused with Ajatashatru, son of Bimbisara, who ruled Haryanka Magadha from 491–461 BCE).
