This map shows the greatest extent of the Chola empire during 1030 under Rajendra Chola I: territories are shown in blue, and subordinates and areas of influence are shown in pink.
The map is corrected to show are of influence and direct control in Sri Lanka. Correction was based on the work of Spencer, G. (1976). The Politics of Plunder: The Cholas in Eleventh-Century Ceylon. The Journal of Asian Studies, 35(3), 405-419. doi:10.2307/2053272.
The correction about the Chola influence in Malay areas is based on https://archive.org/details/earlykingdomsofi0000muno/page/118/mode/2up

The influence added the area of Lamuri based on Tanjore inscription. Andaman is deleted leaving only Nicobar (information on Tanjore inscription).
