establishing the Nurgan Regional Military Commission of 1409–1435. Starting in the 1580s, a Jianzhou Jurchen chieftain, Nurhaci (1558–1626), started to unify Jurchen tribes of the region. Over the next several decades, the Jurchen took control of most of Manchuria. In 1616 Nurhaci founded the Later Jin dynasty, which later became known as the Qing dynasty. The Qing defeated the Evenk-Daur federation led by the Evenki chief Bombogor and beheaded Bombogor in 1640, with Qing armies massacring and deporting Evenkis and absorbing the survivors into the Banners. Chinese cultural and religious influence such as Chinese New Year, the "Chinese god", motifs such as the dragon, spirals, and scrolls, agriculture, husbandry, methods of heating, and material goods such as iron cooking-pots, silk, and cotton spread among the Amur natives including the Udeghes, Ulchis, and Nanais. In 1644, after peasant rebels sacked the Ming dynasty's capital of Beijing, the Jurchens (now called Manchus) allied with Ming general Wu Sangui and seized control of Beijing, overthrowing the short-lived Shun dynasty (1644–1649) and establishing Qing-dynasty rule (1644–1912) over all of China. The Manchu conquest of China involved the deaths of over 25 million people. The Qing dynasty built the Willow Palisade – a system of ditches and embankments – during the later 17th century to restrict the movement of Han civilians into Jilin and Heilongjiang. Only bannermen, including Chinese bannermen, were allowed to settle in Jilin and Heilongjiang. After conquering the Ming, the Qing often identified their state as "China" (中國, Zhongguo; "Middle Kingdom"), and referred to it as Dulimbai Gurun ("Middle Kingdom") in Manchu. In the Qing shilu the lands of the Qing state (including Manchuria and present-day Xinjiang, Mongolia, and Tibet) are thus identified as "the Middle Kingdom" in both the Chinese and Manchu languages in roughly two-thirds of the cases, while the term refers to the traditional Chinese provinces populated by the Han in roughly one third of the cases. It was also common to use "China" (Zhongguo, Dulimbai gurun) to refer to the Qing in official documents, international treaties, and foreign affairs. In diplomatic documents, the term "Chinese language" (Dulimbai gurun i bithe) referred to the 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 Qing explicitly stated that the lands in Manchuria belonged to "China" (Zhongguo, Dulimbai gurun) in
