Reign.
His predecessor was Madhava Varma I (c. 420 – c. 455). He is considered as the greatest ruler of the Vishnukundina dynasty. The Vishnukundina Empire reached its greatest territorial extent under him. He defeated Prithvishena II, the powerful Vakataka king. The daughter of Prithvishena II, Vakataka Mahadevi, was given in marriage to Madhava Varma II. 
This alliance gave them great power and made it easy for the Vishnukundinas to extend their influence to the east coast and vanquishing the petty chieftains lingering on in that area. Madhava Varma II led his arms against Ananda Gotrikas who were ruling over Guntur, Tenali and Ongole, probably enjoying subordinate position under the Pallavas of Kanchipuram.
He built Ramalingesvara Swamy temples at every place where he won a battle.
He occupied Kalinga and invaded the Pallavas of Kanchipuram in his 33rd regnal year. He wrote 'Janasraya'. he had an epithet- 'Trivara Nagara Bhavnagata Sundari Hridaya Nandana' ( The one who brought happiness to the beautiful maidens living in the buildings of the city of Trivara)
After occupying these areas from the Ananda Gotrikas, Madhava Varma II made Amarapura (modern Amaravati) his capital. Keeping in view the constant threat from the Pallavas, he created an out-post to check their activities and appointed his son, Deva Varma and after his death the grandson Madhava Varma III as its Viceroy.
Madhava Varma II next turned his attention against the Vengi kingdom which was under the Salankayanas. The Vengi region was annexed. The Godavari tract became part of the Vishnukundina territory. After these conquests the capital might have been shifted to Bezwada (Vijayawada), a more central location than Amarapura. These extensive conquests entitle him to the title of the lord of Dakshinapatha (southern country). After these various conquests Madhava Varma performed many Asvamedha, Rajasuya and other Vedic sacrifices.

Deva Varma was Madhava Varma’s son. Deva Varma was appointed as the viceroy of Amarapuri.
