Rudra Singha subjugated the Kacharis and Jaintiyas. Who had become virtually independent during the period of the Mughal war in the 17th century."King Rudra Singha was extremely annoyed with the Governor of Bengal, Nawab Murshid Kuli Khan who used to send Khelats to Sargadeo Rudra Singh 'insinuating' thereby that the Ahom Monarch was subordinate to the government of Moghuls. Rudra Singh was 'therefore' keen on organising a formidable confederacy against the Moghuls whom he described as 'enemies of Hinduism'. He despatched his envoys to the Rajas of Morang, Bana-Vishnupur, Nadiya, Cooch Behar, Burdwan, Barahanagar and Tripura seeking their support and cooperation in the fight against the invaders."
