Suteuphaa (reigned 1648–1663), also known as Dihingia Raja, was a king of the Ahom kingdom in medieval Assam. He ascended to the throne after the death of his father, King Susenghphaa (Pratap Singha). His reign was marked by significant political instability and continuous conflict with the Mughal Empire, which was the dominant power in northern India at the time.
During Suteuphaa's rule, the Ahom kingdom faced increasing pressure from Mughal incursions. A key event of his reign was the loss of Guwahati to the Mughals, a strategic fort and a gateway to western Assam. This defeat was a major setback for the Ahom kingdom and signified a period of fluctuating control over the region between the Ahoms and the Mughals. Despite his efforts, Suteuphaa was unable to decisively turn the tide against the powerful Mughal forces.
He was succeeded by his son, Sutamla, who later adopted the Hindu name Jayadhwaj Singha and continued the struggle against the Mughals. Suteuphaa's reign is often viewed as a challenging period that highlighted the vulnerabilities of the Ahom kingdom in the face of external threats, leading to a subsequent shift in Ahom military and diplomatic strategies.
