Suhungmung, who reigned from 1497 to 1539, is the hinge on which the Ahom kingdom turns from a small upper-Assam principality into the dominant power of the Brahmaputra valley. He was the fourteenth king in the line of Sukaphaa, and by tradition the last of the dynasty’s progenitor kings, since every later Ahom sovereign descended from him. He is remembered by his Hindu title Swarganarayan and by the epithet Dihingia Raja, taken from Bakata on the Dihing river, which he made his capital. His long reign saw the annexation of a rival kingdom, the breaking of the first Muslim invasions from the west, a sweeping reform of the state, and the dynasty’s first turn toward Hindu kingship.
The great expansion
For three centuries the eastern frontier of the Ahoms had been contested with the Chutia kingdom based at Sadiya. Suhungmung brought that long rivalry to an end. He took the Chutia dependency of Habung around 1512, held off the counter-attacks that followed, and after recovering the lost ground annexed the rest of the Chutia state in 1523–24, its king and prince falling in the fighting. The conquest folded the Chutia territory, its skilled artisans, and its people into the Ahom system, and Suhungmung set a new frontier office over the region, the Sadiya-Khowa Gohain. It was the kingdom’s first great expansion beyond its original core and a model for how the Ahoms absorbed a neighbour rather than merely defeating it. The historian Yasmin Saikia has called the annexation the turning point in the political evolution of the Tai-Ahom.
He turned next against the Dimasa-Kachari kingdom to the south. Ahom armies marched in 1526, broke the Kacharis by 1531, and pursued them to their capital at Dimapur. Rather than annex the land outright Suhungmung installed a client prince, Detsung, whose later revolt was crushed, and the Kacharis abandoned Dimapur to found a new seat at Maibong. This was part of the long Ahom pressure that would push the Kacharis from one capital to the next over the following centuries. Closer to home he subdued the Baro-Bhuyan chiefs and relocated them, and put down more than one hill revolt. By the end of his reign the Ahom state commanded both the eastern and much of the central valley.
The first invasions from the west
Suhungmung’s reign also met the first serious invasions from the Bengal Sultanate and its commanders, thrusts up the valley that the Ahoms broke. An early raid in 1527 was thrown back to the Burai river. The hardest test was the invasion led by Turbak in 1532, a commander sent from Gaur by the Bengal Sultanate, who won the opening battles before the Ahoms turned the war. It was in this fighting that the warrior-widow Mula Gabharu fell, riding into battle to avenge her husband, an episode the buranjis preserve as one of the earliest celebrated stands by a woman in arms in the region’s history.
The tide turned in 1533. In the decisive battle near the Bharali river Turbak was killed, by tradition unhorsed by a spear and beheaded by the Ahom commander Kanseng Borpatra Gohain, and the buranjis hold that his head was buried at Charaideo. The Ahoms pursued his broken army westward to the Karatoya and reasserted that river as the frontier. The campaign brought them a haul of captured guns and cannon, and the buranjis record the first extensive use of firearms by the Ahoms in these battles. Some scholars hold that the kingdom had first come by the art of the cannon a few years earlier, in the conquest of the Chutias, from whom hand-cannon and heavy guns were taken at Sadiya, though the origin of the technology is debated. Captives taken from Gaur were settled in Assam as the first significant Muslim community there, the Garia, remembered later as skilled brass-workers.
Swarganarayan and the making of the state
Suhungmung was the first Ahom king to take a Hindu title, Swarganarayan, a small act with a long shadow. From it grew the style Swargadeo, “lord of the heavens,” the Assamese rendering of the Tai term Chao-Pha, by which every later Ahom king was known. The title signalled the dynasty’s gradual entry into the Sanskritic, Hindu world of the valley it now ruled, a process that over the next two centuries would draw the Tai kings and the Tai-Ahom people into the wider Assamese mainstream.
His deeper mark was on the machinery of the state. Around 1510 he ordered the first recorded census, a count of the adult men of the kingdom together with a survey of clans and crafts, the beginning of the manpower system on which Ahom armies and public works would rest for two centuries. He enlarged the council of ministers, creating the third of the great Gohains, the Borpatra Gohain, in 1527, and set new provincial offices over the frontiers he had won, among them the Sadiya-Khowa Gohain in the east and the Marangi-Khowa Gohain in the Dhansiri valley. The keeping of the buranjis and the routine of administration both grew more elaborate under him, the foundations a later administration would systematise.
Death and legacy
Suhungmung had four sons, and his household was not without scandal, for he raised the daughter of a goldsmith to be his senior queen. His reign ended in blood. In 1539 he was killed in his sleep by a servant, Ratiman, in a conspiracy that tradition links to his eldest son and successor, Suklenmung, who moved the capital to Garhgaon and consolidated what his father had won. Yet the manner of his death does nothing to diminish the reign. Suhungmung inherited a hill principality and left behind the leading state of the valley, its borders pushed out on every side and its first invaders thrown back, and the empire the Ahoms became, with the apex they reached a century and a half later at Saraighat and Rangpur, rests on the expansion he led.
