Yesin Timur, Kublai’s grandson, after the victory at Nhamo, leads his Mongol forces down the Irrawaddy River valley, captures the flourishing walled city of Pagan (from which King Narthihapate had fled south to Bassein) and establishes a puppet government.

Narthihapate decides, under the circumstances, to finally recognize Mongol suzerainty, but his son murders him soon after, in 1287.

The two-hundred and fifty-year-old Pagan Empire now disintegrates.

The kingdom is fractured into several small power centers as the Mongols do not fill the power vacuum in the searing heat of the Irrawaddy valley.

The Mongol army instead stays farther north in Tagaung (present-day northern Mandalay Region).
