The Shungas originated from Magadha, and controlled areas of the central and eastern Indian subcontinent from around 187 to 78 BCE. The dynasty was established by Pushyamitra Shunga, who overthrew the last Maurya emperor. Its capital was Pataliputra, but later emperors, such as Bhagabhadra, also held court at Vidisha, modern Besnagar in Eastern Malwa.

Pushyamitra Shunga ruled for 36 years and was succeeded by his son Agnimitra. There were ten Shunga rulers. However, after the death of Agnimitra, the empire rapidly disintegrated; inscriptions and coins indicate that much of northern and central India consisted of small kingdoms and city-states that were independent of any Shunga hegemony. The empire is noted for its numerous wars with both foreign and indigenous powers. They fought battles with the Mahameghavahana dynasty of Kalinga, Satavahana dynasty of Deccan, the Indo-Greeks, and possibly the Panchalas and Mitras of Mathura.

Art, education, philosophy, and other forms of learning flowered during this period including small terracotta images, larger stone sculptures, and architectural monuments such as the Stupa at Bharhut, and the renowned Great Stupa at Sanchi. The Shunga rulers helped to establish the tradition of royal sponsorship of learning and art. The script used by the empire was a variant of Brahmi and was used to write the Sanskrit language. The Shunga Empire played an imperative role in patronising Indian culture at a time when some of the most important developments in Hindu thought were taking place. This helped the empire flourish and gain power.
