Bindusara inherited a large empire that consisted of what is now, Northern, Central and Eastern parts of India along with parts of Afghanistan and Baluchistan. Bindusara extended this empire to the southern part of India, as far as what is now known as Karnataka. He brought sixteen states under the Mauryan Empire and thus conquered almost all of the Indian peninsula (he is said to have conquered the 'land between the two seas' - the peninsular region between the Bay of Bengal and the Arabian Sea). Bindusara didn't conquer the friendly Dravidian kingdoms of the Cholas, ruled by King Ilamcetcenni, the Pandyas, and Cheras. Apart from these southern states, Kalinga (the modern Orissa) was the only kingdom in India that didn't form the part of Bindusara's empire. It was later conquered by his son Ashoka, who served as the viceroy of Ujjaini during his father's reign.
Bindusara's life has not been documented as well as that of his father Chandragupta or of his son Ashoka. Chanakya continued to serve as prime minister during his reign. According to the mediaeval Tibetan scholar Taranatha who visited India, Chanakya helped Bindusara "to destroy the nobles and kings of the sixteen kingdoms and thus to become absolute master of the territory between the eastern and western oceans." 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 Bindusara could not suppress it in his lifetime. It was crushed by Ashoka after Bindusara's death.
Ambassadors from the Seleucid Empire (such as Deimachus) and Egypt visited his courts. He maintained good relations with the Hellenic World.
Unlike his father Chandragupta (who was a follower of Hinduism and Jainism), he believed in the Ajivika sect (an ancient Indian sect that also had the Brahmin Chanakya as a follower). Bindusara's guru Pingalavatsa (alias Janasana) was a Brahmin of the Ajivika sect. Bindusara's wife, Queen Subhadrangi (alias Queen Aggamahesi) was a Brahmin also of the Ajivika sect from Champa (present Bhagalpur district). It is notable that Chanakya,the acharya Emperor Chandragupt was also an Ajivika. Bindusara is accredited with giving several grants to Brahmin monestaries (Brahmana-bhatto)
