Q. Chola dynasty founder Vijayalaya Chola captured the control of Thanjavur from which dynasty in the middle of the ninth century?
Answer: Mutharaiyar dynasty
Notes: A minor chiefly family known as the Muttaraiyar held power in the Kaveri delta. They were subordinate to the Pallava kings of Kanchipuram. Vijayalaya, who belonged to the ancient chiefly family of the Cholas from Uraiyur, captured the delta from the Muttaraiyar in the middle of the ninth century. He built the town of Thanjavur and a temple for goddess Nishumbhasudini there.
