Raghunātha Sēthupati II (Kilavan Sēthupati) (1671AD. to 1710 AD.)

Kilavan Sēthupati was the greatest ruler among the Marava kings. He was helpful to Chokkanātha Nāyak. The Nāyak king conferred him a title Para Rāja kēsari (Lion to alien kings). He annexed some territories of Madurai Kingdom. He opposed the spread of Christian missionary activities.

Kilavan Sēthupati liberated the Marava country from the control of Madurai Nāyak. After defeating Rāņi Maňgammāļ's army, he declared independent Marava country in 1707. He shifted his head quarters from Pughalūr to Rāmnāď. Kilavan Sēthupati established the Nalcottal pāļayam (later Sivaganga) and appointed Udaya Thēvar as Governor. He served well for the development of Hinduism.

He endowed villages to a temple at Thiruvadanai and Kalaiyar Koil. He constructed a fort around the Rāmanāthapuram, the capital city. He constructed a dam across the Vaigai River. His rule was marked as the golden age of the Maravas. Kilavan Sēthupati was succeeded by Bhavani Shankarathēvar and Thandathēvar.

After Kilavan Sēthupati the kingdom was divided into two and new Sivaganga Kingdom emerged. During the later period of Sēthupati's rule, Rāmnāď was reduced to a zamin level. Then it was brought under the control of the British rulers. Finally it became a part of the Indian Union. Among the later Sēthupatis, Bāskara Sēthupati was an exceptionally enlightened zamindar. He was educated in English. He honored Swami Vivēkānanda who attended the parliament of Religion at Chicago. The social life under Sēthupati's rule was good.
