Between 641 CE and 705 CE some kings, except Jayasimha I and Mangi Yuvaraja, ruled for very short durations. Then periods with weak rulers followed. At this time, the Rashtrakutas removed the Western Chalukyas of Badami. The weak rulers of Vengi had to face the Rashtrakutas. There was no Eastern Chalukya ruler who could fight against them. During the period of Gunaga Vijayaditya III, the Rashtrakuta emperor Amoghavarsha treated him as his ally (supporter). After Amoghavarsha's death, Vijayaditya made the state independent.
