Suremphaa, or Rajeswar Singha, the fourth son of Rudra Singha, became the king of the Ahom kingdom after the death of his brother King Pramatta Singha. Rudra Singha's third son, Mohanmala Gohain, was considered ineligible for kingship as his face was pitted with smallpox marks. According to the norm established after Sulikphaa Lora Roja, an Ahom prince had to be free from any physical disability, defects or deformities to become a king.

Sukhrungphaa or Swargadeo Rudra Singha was the 30th Ahom king, reigning from 1696 to 1714 A.D. His father Gadadhar Singha freed Assam from the Mughal disturbances and internal conspiracies, thereby Rudra Singha inherited a stable state and government and had the advantage of the solid foundations laid by his father. He devoted his time to transform Assam into a first-rate power in India. He stopped the persecution of the Neo-Vaisnava sect and built temples, several public works, and patronized art, literature, and culture. Rudra Singha is also famed for being the real father of Ahom architecture. He giving up the isolationist policy of his predecessors forged diplomatic ties with various states of that time and established extensive trade with Bengal.
