For almost 300 years from 1004 CE, the Kongu Cholas ruled autonomously. Chola monarch Raja Raja's general named, Kalimurka Vikrama was the founder of the dynasty and bore the title Konattar. The rulers of the 'Konattar' line adopted Chola titles and surnames. They came from the Konadu region (Pudukkottai) and ruled as a branch of Tanjore Cholas but were named as Kongu Cholas. The Kongu country came under the control of Vikarama Chola and Rajadhiraja, the two Kongu rulers who served as the later contemporaries of the Imperial Chola king Rajendra I and Kulottunga I, who ruled between 1070 CE and 1120 CE. Vikrama Chola III was the last ruler of the Kongu Chola line. During his time major parts of the Kongu region were under the Pandyas.
