Period: 321 BCE- 185 BCE | Capital: Patliputra |
Chandragupta Maurya (321 BCE-297 BCE) | – Parishishtaparvan, written by Hemachandra, identifies Chandragupta as the grandson of the chief of the peacock tamers clan (mayura-poshakas). – He was the chief architect of the Mauryan empire and built a vast empire, which included Bihar, Nepal, western and north-western India, and the Deccan. – War with Seleucus: The Mauryans annexed several areas in the Hindu Kush region in 305 BC. These regions were governed by satraps (governors) appointed by Alexander during his campaign. This move prompted Seleucus to campaign against Chandragupta to secure the eastern border of his empire. – Treaty with Seleucus Nicator (303 BCE): According to the terms of this treaty, Seleucus ceded Chandragupta the territories of Arachosia (the Kandahar area of south-east Afghanistan), Gedrosia (south Baluchistan), and Paropomisadai (area between Afghanistan and the Indian subcontinent). Alongside the treaty, the general rights of intermarriage between the Greeks and the Indians were also acknowledged. – Greek historians Megasthenes and Dionysius resided at the Mauryan court. – Religion: Chandragupta gave up his throne and became a disciple of Jain teacher Bhadrabahu. |
Bindusara (297 BCE-273 BCE) | – The Mahabhashya refers to Chandragupta’s successor as Amitraghata (a slayer of enemies). He is also referred to as “Amitrochates” in Greek sources. – Conquest: He brought sixteen states under the Mauryan Empire and thus conquered almost all of the Indian peninsula. He conquered ‘the land between the two seas’, i.e., the Arabian Sea and the Bay of Bengal. He continued the empire’s expansion well into the Deccan, stopping around the region of Karnataka. – Deimachus was the Seleucid emperor Antiochus I’s ambassador at Bindusara’s court. – Religion: He joined the Ajivika sect. |

Reason for invading Kalinga: Kalinga was a glorious and prosperous region that valued freedom and was talented in the arts. Kalinga had some important ports as well as a strong navy. After witnessing so much loss of life during the war, Ashoka abandoned violence and established peace and harmony in his kingdom. – Religion: Proponent of Buddhism; Organised 3rd Buddhist Council at Pataliputra. – Dhamma: The word ‘Dhamma’ is the Prakrit form of the Sanskrit word ‘Dharma’.

Shatadhanvan (195 BCE – 187 BCE) | – According to Puranas, Shatadhanvan succeeded Devavarman Maurya. – The empire lost some of its territories because of invasions from outside and neighbouring kingdoms during his reign |
Brihadratha (187 BCE – 185 BCE) | – Brihadratha was the last Mauryan emperor. – According to some sources, he was assassinated by his Brahman commander-in-chief, Pushyamitra Shunga, who went on to establish the Shunga Empire. |
