The Chola Dynasty (Tamil: சோழர் குலம், IPA: ['ʧoːɻə]) was a Tamil ynasty that ruled primarily in southern India until the 13th century. The dynasty originated in the fertile valley of the Kaveri River. Karikala Chola was the most famous among the early Chola kings, while Rajaraja Chola, Rajendra Chola I and Kulothunga Chola I were notable emperors of the medieval Cholas.
