The Dehong Dai and Jingpo Autonomous Prefecture is an autonomous prefecture in western Yunnan province, China. It is bordered by Baoshan to the east and Myanmar's Kachin State to the west. Its titular ethnic minorities are the Dai and Jingpo, who make up 28 and 11 percent of the prefecture's population, respectively.

Narathihapate was the last king of the Pagan Empire who reigned from 1256 to 1287. The king is known in Burmese history as the "Taruk-Pyay Min" for his flight from Pagan (Bagan) to Lower Burma in 1285 during the first Mongol invasion (1277–87) of the kingdom. He eventually submitted to Kublai Khan, founder of the Yuan dynasty in January 1287 in exchange for a Mongol withdrawal from northern Burma. But when the king was assassinated six months later by his son Thihathu, the Viceroy of Prome, the 250-year-old Pagan Empire broke apart into multiple petty states. The political fragmentation of the Irrawaddy valley and its periphery would last for another 250 years until the mid-16th century.
