Wars against Kadavas Sundara Pandyan besieged the city fortress of Sendamangalam and fought with the Kadava king Kopperunchingan II. However he restored Kopperunchingan to his throne and gave him his country back. He also conquered Magadai and Kongu countries during his campaigns against Kadavas and Hoysalas Invasion of Sri Lanka Responding to an appeal for help from a minister in Sri Lanka, Jatavarman Sundara Pandyan intervened in 1258 and made Chandrabhanu of Tambralinga, a Savakan usurper of the Jaffna kingdom submit to Pandyan rule and annually offer precious jewels and elephants in tribute. A second attempt by Chandrabhanu to invade the south of the island from the north prompted the Prince Jatavarman Veera Pandyan I, brother and lieutenant of Sundara Pandyan I to intervene again in 1262-1264 on Sundara Pandyan I's behalf.

Pandyan forces killed the Telugu ruler Vijaya Gandagopala and captured Kanchipuram in 1258. This bought them in conflict with the Kakatiyas under Ganapati II. Sundara Pandiyan I defeated a Telugu army at Mudugur in the current Nellore district and performed a virabisheka to commemorate the end of his campaign. However Ganapathi II later defeated Kopperunchingan II who was by then a Pandyan ally and recaptured territories up to Kanchipuram. The Kadava Pallava Kopperinjungan II was followed by very weak successors and Sundara Pandyan annexed Kanchi, Nellore and Visayavadai (modern Vijayawada) regions to the Pandyan Kingdom.
