Tranquility was restored temporarily by a marriage between Vijayaditya II's son, Vishnuvardhana V, and the Ratta princess Shilamahadevi, a sister of Karka of the Gujarat Rashtrakuta branch. However, Vishnuvardhana V attacked the northern Kalachuri feudatory of the Rashtrakutas in Tripuri, central India, and captured Elichpur near Nasik. Amoghavarsha I killed Vishnuvardhana V in 846 but continued a friendly relationship with the next Eastern Chalukya ruler Gunaga Vijayaditya III, and suppressed the recalcitrant Alupas of South Canara under prince Vimaladitya in 870. Likewise, Amoghavarsha I maintained friendly interactions with the Pallava who were busy keeping the Pandyas at bay. The Pallavas had marital ties with the Rashtrakutas as well. Nandivarman was married to a Ratta princess, Sankha, and their son was also called "Nripathunga". This has prompted historians to suggest that the Pallava king must have married Nrupatunga Amoghavarsha I's daughter.
