Suhungmung (reign 1497–1539) (Swarganarayan, Dihingia Raja) (
Assamese: স্বৰ্গদেউ চুহুংমুং), was one of the most important
Ahom kings, who ruled at the cusp of Assam's medieval history. His reign broke from the early Ahom rule and established a multi-ethnic polity in his kingdom. Under him the
Ahom Kingdom expanded greatly for the first time since
Sukaphaa, at the cost of the
Sutiya and the
Kachari kingdoms. He also successfully defended his kingdom against the first Muslim invasions under Turbak Khan. During his time, the
Khen dynasty collapsed and the
Koch dynasty ascended in the
Kamata kingdom. His general, Tonkham, pursued the Muslims up to the
Karatoya river, the western boundary of the erstwhile
Kamarupa Kingdom, the farthest west an Ahom king had ventured in its entire six hundred years of rule.
