The inscriptions issued by the Chola kings are found from various parts of the old Madras state. They give evidences for the Cholas' attack on Kerala.
Attacks on south Kerala regions are mentioned in the inscriptions discovered from the temples at Cholapuram, Kanyakumari, Darsanam Koppu, Thirunanthikarai and Sucheendram.
The Thirallaisthanam inscription reveals the friendship between Aditya Cholan and Sthanuravi. Rajendra Chola's (AD 1012-1044) Thiruvalangad inscription has mentioned about the Chola attack on Vizhinjam. The Cholapuram inscription is about the retreat of Kulothunga Cholan to Kottattu.
