During the rule of Krishna II, the empire faced a revolt from the Eastern Chalukyas and its size decreased to the area including most of the Western Deccan and Gujarat. Krishna II ended the independent status of the Gujarat branch and brought it under direct control from Manyakheta. Indra III recovered the dynasty's fortunes in central India by defeating the Paramara and then invaded the doab region of the Ganges and Jamuna rivers. He also defeated the dynasty's traditional enemies, the Pratiharas and the Palas, while maintaining his influence over Vengi. The effect of his victories in Kannauj lasted several years according to the 930 copper plate inscription of Emperor Govinda IV. After a succession of weak kings during whose reigns the empire lost control of territories in the north and east, Krishna III the last great ruler consolidated the empire so that it stretched from the Narmada River to Kaveri River and included the northern Tamil country (Tondaimandalam) while levying tribute on the king of Ceylon.
