Rajaraja and Rajendra I were the most important Chola rulers. One of the most remarkable exploits in the reign of Rajendra I was the march across Kalinga to Bengal in which Chola armies crossed the river Ganga and defeated two local kings. This expedition, which was led by a Chola general, took place in 1022 CE and followed in reverse the same route which the great conqueror Samudragupta had followed. To commemorate this occasion, Rajendra I assumed the title of Gangaikonda Chola i.e. the Chola who conquered the Ganga. He also built a new capital near the mouth of river Krishna and called it Gangaikonda Cholapuram.
