Chinese Communist evaluations of China's foreign conquest dynasties, like those of earlier Chinese historians, have been hostile, at least on the most vulgar level of historical writing. This comes as no surprise, for the conquest dynasties occupied all or part of China by military force and often governed badly. For the Chinese Communist historians these conquerors carry the additional onus of being feudalists, or worse, feudalists who allowed the feudal economy to stagnate. This attitude is particularly marked in the treatment of the more recent foreign dynasties, the Khitan Liao dynasty (916–1124), the Jurchen Chin dynasty (1115–1234), the Tangut Hsi Hsia dynasty (1032–1227), the Manchu Ch'ing dynasty (1644–1911) and the one discussed here, the Mongol Yüan dynasty (1220–1367).
