In the early 12th century the Tungusic Jurchen people (the ancestors of the later Manchu people) originally lived in the forests in the eastern borderlands of the Liao Empire, and were Liao's tributaries, overthrew the Liao and formed the Jin dynasty (1115–1234). They went on to control parts of Northern China and Mongolia after a series of successful military campaigns. Most of the surviving Khitan either assimilated into the bulk of the Han Chinese and Jurchen population, or moved to Central Asia. However, according to DNA tests conducted by Liu Fengzhu of the Nationalities Research Institute of the Chinese Academy of Social Sciences, the Daur people, still living in northern Manchuria (northeast China 东北), are also descendants of the Khitans.
