Qin dynasty
Note: King Zhaoxiang of Qin (秦昭襄王) had already been ruling Qin for 51 years when Qin annihilated the Zhou dynasty; however the other six warring states were still independent regimes. Some Chinese historiographers thus used the next year (the 52nd year of King Zhaoxiang of Qin) as the official succession from the Zhou dynasty.
Manchukuo
The Qing dynasty, which replaced the Shun and Ming dynasties in China, was founded by Manchus from Manchuria (modern Northeast China). The Manchu emperors separated their homeland in Jilin and Heilongjiang from the Han Liaoning province with the Willow Palisade. This ethnic division continued until the Qing dynasty encouraged massive immigration of Han in the 19th century during Chuang Guandong to prevent the Russians from seizing the area from the Qing. After conquering the Ming, the Qing identified their state as "China" (中國, Zhongguo; "Central Realm") and referred to it as "Dulimbai Gurun" in Manchu. The Qing equated the lands of the Qing state (including present day Manchuria, Xinjiang, Mongolia, Tibet and other areas) as "China" in both the Chinese and Manchu languages, defining China as a multi-ethnic state, rejecting the idea that China only meant Han areas, proclaiming that both Han and non-Han peoples were part of "China", using "China" to refer to the Qing in official documents, international treaties, and foreign affairs, and the "Chinese language" (Dulimbai gurun i bithe) referred to Chinese, Manchu, and Mongol languages, and the term "Chinese people" (中國人 Zhongguo ren; Manchu: Dulimbai gurun i niyalma) referred to all Han, Manchus, and Mongol subjects of the Qing. The lands in Manchuria were explicitly stated by the Qing to belong to "China" (Zhongguo, Dulimbai gurun) in Qing edicts and in the Treaty of Nerchinsk.
