In 1252 Möngke Khan placed his brother Kublai in charge of invading Dali. In 1253 Kublai's army crossed the Jinsha River and received the surrender of Duan Xingzhi, who presented to Möngke in 1256 maps of Yunnan. Duan Xingzhi of Dali was enfeoffed as Maharaja (摩诃罗嵯) by Kublai Khan, and the Duan imperial family continued to hold the title of Maharaja in Yunnan as vassals to the Mongols under the supervision of Borjigin imperial princes and Muslim governors. The Duan family reigned in Dali while the governors served in Kunming. After the Ming conquest of Yunnan, the members of the Duan clan were scattered in various distant areas of China by the Hongwu Emperor.
