Rajaraja is the right answer.  

933 A.D marked the beginning of the Chola rule in the island of Shri Lanka. During this time the king of the Chola dynasty was Rajaraja Chola. He sent his army to conquer the Anuradhapura Kingdom in the North of the Shri Lanka and combined it to the  Chola Empire. Though Rajaraja Chola made the northern part of the island its province, most of the island was consequently captured and consolidated as a region of the large empire of the Cholas during the reign of Rajendra Chola.
