The Greeks called him Amitrochates - the Greek word for the Sanskrit 'Amitraghata' (Slayer of Enemies).Bindusara's life hasn't been documented as well as his father Chandragupta or his son Ashoka. The philosopher Chanakya served as prime minister during his reign. During his rule, the citizens of Taxila revolted twice. The reason for the first revolt was the maladministration of Suseema, his eldest son. The reason for the second revolt is unknown, but it could not be suppressed by Bindusara due to his untimely death, but was later crushed by Ashoka.
