Suhungmung (r. 1497–1539), or Dihingia Roja was one of the most prominent Ahom Kings who ruled at the cusp of Assam's medieval history.

He also successfully defended his kingdom against Muslim invasions, first by a general called Bar Ujjir and another by Turbak Khan.

His general, Ton-kham, pursued the Muslims up to the Karatoya river,[1] the western boundary of the erstwhile Kamarupa Kingdom, the farthest west an Ahom military force had ventured in its entire six hundred years of rule.

Under Suhungmung the Ahom Kingdom acquired a vision of an extended polity and consolidated rule.

[3][better source needed] As he embarked on military expeditions he organized the first recorded survey of the adult population in 1510 to consolidate and reorganize the militia.

In 1522, the Ahoms fought back, re-occupied their lost territories and erected a fort at Dibrumukh (Dibrugarh).

Suhungmung then extended the Ahom Kingdom to the mouth of the Tiphao River, where a new fort was constructed.

Upon annexing the Chutia territories, the Ahoms came in contact with hill tribes like Miris, Abors, Mishmis and Daflas.

Suhungmung established the office of the Sadiyakhowa Gohain and gave charge to Phrasengmung Borgohain to look after the newly acquired Sadiya region.

The rest of the newly acquired territories were divided among the Buragohain and Borgohain, while new offices were created to administer the country more efficiently.

The first Muslim invasion of the Ahom Kingdom occurred in 1527, but it was defeated and pushed back to the Burai River.

Suhunmung met his death in 1539 as a result of a conspiracy hatched by his eldest son Suklenmung who was highly dissatisfied with his father's disgraceful act of marrying the daughter of a Sonari (goldsmith) and making her the Borkonwari (Seniormost Queen).
