The Shunga dynasty was the fifth ruling dynasty of Magadha and controlled most of the northern Indian subcontinent from around 187 to 73 BCE. The dynasty was established by Pushyamitra, after taking the throne of Magadha from the Mauryas. The Shunga Empire's capital was Pataliputra, but later emperors such as Bhagabhadra also held court at Besnagar in eastern Malwa. This dynasty is also responsible for successfully fighting and resisting the Greeks in Shunga-Greek War.

Pushyamitra Shunga or Pushpamitra Shunga was the founder and the first ruler of the Shunga Empire which he established to succeed the Maurya Empire. His original name was Puṣpaka or Puṣpamitra and the confusion between Puṣyamitra and Puṣpamitra arose because of the erroneous readings of 'p' and 'y' in the manuscripts.
