Vishnuvardhana IV

Vishnuvardhana IV was the tenth king of the Eastern Chalukyas, which ruled the region of Vengi. He reigned from 772 AD to 808 AD. He had martial ties with the imperial Rashtrakutas. The Rashtrakuta emperor Dhruva Dharavarsha gave his daughter, Silabhattarika, in marriage to Vishnuvardhana IV to forge an alliance with the Western Ganga Dynasty after defeating and humbling him in 784. His predecessor was Vijayaditya I (755 – 772 AD) and was succeeded by Vijayaditya II (808 – 847 AD).
