The Vishnukundina Empire was an Indian imperial power controlling the Deccan, Orissa and parts of South India during the 5th and 6th centuries, carving land out from the Vakataka Empire. It played an important role in the history of the Deccan during the 5th and 6th centuries.
By 514, the Vakatakas were reduced to the areas of present-day Telangana area. The area north of the Godavari, Kalinga, became independent. The area south of the Krishna River fell to the Pallavas. The Vishnukundin reign came to an end with the conquest of the eastern Deccan by the Chalukya, Pulakeshin II. Pulakeshin appointed his brother Kubja Vishnuvardhana as Viceroy to rule over the conquered lands. Eventually Vishnuvardhana declared his independence and started the Eastern Chalukya dynasty.
