The Manchu name is descended from the Jurchens, the rulers of the Jin dynasty (1115-1234). The name Manchu (M. Manju) was adopted in 1635 to designate the Jurchen people. The eastern tour of 1778 highlighted the Inner Asian dimension of the Qing state, a multiethnic polity that had roots in Inner Asia, an area that linked China proper to the Eurasian continent. The Qing rulers were Manchus, a non-Han ethnic group from northeast Asia who were ruling over a multiethnic Empire that included Manchus, Hans, Mongols, Tibetans, and Uyghurs. They descended from the Jurchens, the rulers of the Jin dynasty (1115-1234). The Qing dynasty was thus the last of a succession of non-Han dynasties that had ruled over imperial China for about half of its recorded history.
