Bindusara () was the second Mauryan emperor of Magadha in Ancient India. The ancient Greco-Roman writers called him Amitrochates, a name likely derived from his Sanskrit title Amitraghāta ("slayer of enemies").
Bindusara was the son of the dynasty's founder Chandragupta and the father of its most famous ruler Ashoka. His life is not documented as well as the lives of these two emperors. Much of the information about him comes from legendary accounts written several hundred years after his death. Bindusara consolidated the empire created by his father.
The 16th century Tibetan Buddhist author Taranatha credits his administration with extensive territorial conquests in southern India, but some historians doubt the historical authenticity of this claim.
Background
Ancient and medieval sources have not documented Bindusara's life in detail. Much of the information about him comes from Jain legends focused on Chandragupta and the Buddhist legends focused on Ashoka. The Jain legends, such as Hemachandra's Parishishta-Parvan were written more than a thousand years after his death. Most of the Buddhist legends about Ashoka's early life also appear to have been composed by Buddhist writers who lived several hundred years after Ashoka's death, and are of little historical value. While these legends can be used to make several inferences about Bindusara's reign, they are not entirely reliable because of the close association between Ashoka and Buddhism.
Buddhist sources that provide information about Bindusara include Divyavadana (including Ashokavadana and Pamsupradanavadana), Dipavamsa, Mahavamsa, Vamsatthappakasini (also known as Mahvamsa Tika or "Mahavamsa commentary"), Samantapasadika, and the 16th century writings of Taranatha. According to the 12th century Jain writer Hemachandra's Parishishta-Parvan, the name of Bindusara's mother was Durdhara. Other Puranas give different names for Chandragupta's successor; these appear to be clerical errors. The Jain work Rajavali-Katha states that his birth name was Simhasena.
Both Buddhist and Jain texts mention a legend about how Bindusara got his name. Both accounts state that Chandragupta's minister Chanakya used to mix small doses of poison in the emperor's food to build his immunity against possible poisoning attempts. One day, Chandragupta, not knowing about the poison, shared his food with his pregnant wife. According to the Buddhist legends (Mahavamsa and Mahavamsa Tikka), the queen was seven days away from delivery at this time. Chanakya arrived just as the queen ate the poisoned morsel. Realizing that she was going to die, he decided to save the unborn child. He cut off the queen's head and cut open her belly with a sword to take out the foetus. Over the next seven days, he placed the foetus in the belly of a goat freshly killed each day. After seven days, Chandragupta's son was "born". He was named Bindusara, because his body was spotted with drops ("bindu") of goat's blood. The Jain text Parishishta-Parvan names the queen as Durdhara, and states that Chanakya entered the room the very moment she collapsed. To save the child, he cut open the dead queen's womb and took the baby out. By this time, a drop ("bindu") of poison had already reached the baby and touched its head. Therefore, Chanakya named him Bindusara, meaning "the strength of the drop".
Family
The prose version of Ashokavadana names three sons of Bindusara: Sushima, Ashoka and Vigatashoka. The mother of Ashoka and Vigatashoka was a woman named Subhadrangi, the daughter of a Brahmin of the Champa city. When she was born, an astrologer named Pingalwatsa predicted that one of her sons would be a king, and the other a religious man. When she grew up, her father took her to Bindusara's palace in Pataliputra. Bindusara's wives, jealous of her beauty, trained her as the royal barber. Once, when the Emperor was pleased with her hairdressing skills, she expressed her desire to be a queen. Bindusara was initially apprehensive about her low class, but made her the chief queen after learning about her Brahmin descent. The couple had two sons: Ashoka and Vigatashoka. Bindusara did not like Ashoka because his "limbs were hard to the touch".
Another legend in Divyavadana names Ashoka's mother as Janapada-kalyanibut according to scholar Ananda W. P. Guruge, this is not a name, but an epithet. According to the Vamsatthappakasini (Mahavamsa Tika), the name of Ashoka's mother was Dhamma. The Mahavamsa states that Bindusara had 101 sons from 16 women. The eldest of these was Sumana / Sushima, and the youngest was Tishya (or Tissa). Ashoka and Tishya were born to the same mother.
Reign
Historian Upinder Singh estimates that Bindusara ascended the throne around 297 BCE.
Territorial conquests

The 16th century Tibetan Buddhist author Taranatha states that Chanakya, one of Bindusara's "great lords", destroyed the nobles and kings of 16 towns and made him master of all the territory between the western and the eastern seas (Arabian Sea and the Bay of Bengal). According to some historians, this implies conquest of Deccan by Bindusara, while others believe that this only refers to suppression of revolts.
Sailendra Nath Sen notes that the Mauryan empire already extended from the western sea (beside Saurashtra) to the eastern sea (beside Bengal) during Chandragupta's reign. Besides, Ashoka's inscriptions found in southern India do not mention anything about Bindusara's conquest of Deccan (southern India). Based on this, Sen concludes that Bindusara did not extend the Mauryan empire, but managed to retain the territories he inherited from Chandragupta.
K. Krishna Reddy, on the other hand, argues that Ashoka's inscriptions would have boasted about his conquest of southern India, had he captured Deccan. Reddy, therefore, believes that the Mauryan empire extended up to Mysore during Bindusara's reign. According to him, the southernmost kingdoms were not a part of the Mauryan empire, but probably acknowledged its suzerainty.
Alain Daniélou believes that Bindusara inherited an empire that included the Deccan region, and made no territorial additions to the empire. Daniélou, however, believes that Bindusara brought the southern territories of the Cheras, the Cholas and the Satyaputras under nominal Mauryan control, although he could not overcome their armies. His theory is based on the fact that the ancient Tamil literature alludes to Vamba Moriyar (Mauryan conquest), although it does not provide any details about the Mauryan expeditions. According to Daniélou, Bindusara's main achievement was organization and consolidation of the empire he inherited from Chandragupta.
Takshashila revolt
The Mahavamsa suggests that Bindusara appointed his son Ashoka as the viceroy of Ujjayini. Ashokavadana states that Bindusara sent Ashoka to lay siege to Takshashila. The Emperor refused to provide any weapons or chariots for Ashoka's expedition. The devatas (deities) then miraculously brought him soldiers and weapons. When his army reached Takshashila, the residents of the city approached him. They told him that they only opposed Bindusara's oppressive ministers; they had no problem with the Emperor or the prince. Ashoka then entered the city without opposition, and the devatas declared that he would rule the entire earth one day. Shortly before Bindusara's death, there was a second revolt in Takshashila. This time, Sushima was sent to quell the rebellion, but he failed in the task. However, the Parishishta-Parvan states that Chanakya continued to be Bindusara's prime minister. It mentions a legend about Chanakya's death: Chanakya asked the emperor to appoint a man named Subandhu as one of his ministers. However, Subandhu wanted to become a higher minister and grew jealous of Chanakya. So, he told Bindusara that Chanakya had cut open the belly of his mother. After confirming the story with the nurses, Bindusara started hating Chanakya. As a result, Chanakya, who was already a very old man by this time, retired and decided to starve himself to death. Meanwhile, Bindusara learned of the detailed circumstances of his birth, and implored Chanakya to resume his ministerial duties. When Chanakya refused to oblige, the Emperor ordered Subandhu to pacify him. Subandhu, while pretending to appease Chanakya, burned him to death. Shortly after this, Subandhu himself had to retire and become a monk due to Chanakya's curse.
Ashokavadana suggests that Bindusara had 500 royal councillors. It names two officials – Khallataka and Radhagupta – who helped his son Ashoka became the emperor after his death. Deimachos seems to have written a treatise entitled "On Piety" (Peri Eusebeias). The 3rd century Greek writer Athenaeus, in his Deipnosophistae, mentions an incident that he learned from Hegesander's writings: Bindusara requested Antiochus to send him sweet wine, dried figs and a sophist. Antiochus replied that he would send the wine and the figs, but the Greek laws forbade him to sell a sophist. Bindusara's request for a sophist probably reflects his intention to learn about the Greek philosophy.
Diodorus states that the king of Palibothra (Pataliputra, the Mauryan capital) welcomed a Greek author, Iambulus. This king is usually identified as Bindusara. Pliny states that the Ptolemaic king Philadelphus sent an envoy named Dionysius to India. According to Sailendra Nath Sen, this appears to have happened during Bindusara's reign.
