Treaty of Asurar Ali
The Treaty of Asurar Ali in early February 1639 was signed between the Mughal faujdar Allah Yar Khan and the Ahom general Momai Tamuli Borbarua. The treaty came at the end of a period of Mughal efforts to drive into the Ahom kingdom that began in 1615, and followed a decisive Ahom victory over the Mughals at Duimunisila in November 1638.
