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.
