the ethnic group now known as uyghur people was not known by that name before the 20th century. the uzbeks of yaqub beg were called "andijanis" or "kokandis", while the uyghurs in the tarim basin were known as "turki". uyghur immigrants from the tarim basin to ili were called "taranchi". the modern name "uyghur" was assigned to this ethnic group by the soviet union in 1921 at a conference in tashkent, with the name "uyghur" taken from the old uyghur khaganate. as a result, sources from the period of the dungan revolt make no mentions of uyghurs.
