History: Old China

Within its borders, the Northern Song Dynasty had a population of some 100 million people. The Song Dynasty was a culturally rich period for philosophy and the arts. Landscape art and portrait painting were brought to new levels of maturity and complexity after the Tang Dynasty, and social elites gathered to view art, share their own, and trade precious artworks. Philosophers such as Cheng Yi and Chu Hsi reinvigorated Confucianism with new commentary, infused Buddhist ideals, and emphasized a new organization of classic texts that brought about the core doctrine of Neo-Confucianism.
In 1271, the Mongol leader and fifth Khagan of the Mongol Empire Kublai Khan established the Yuan Dynasty, with the last remnant of the Song Dynasty falling to the Yuan in 1279. Before the Mongol invasion, Chinese dynasties reportedly had approximately 120 million inhabitants; after the conquest was completed in 1279, the 1300 census reported roughly 60 million people. A peasant named Zhu Yuanzhang overthrew the Mongols in 1368 and founded the Ming Dynasty. Ming Dynasty thinkers such as Wang Yangming would further critique and expand Neo-Confucianism with ideas of individualism and innate morality that would have tremendous impact on later Japanese thought. Chosun Korea also became a nominal vassal state of Ming China and adopted much of its Neo-Confucian bureaucratic structure.
Under the Ming Dynasty, China had another golden age, with one of the strongest navies in the world, a rich and prosperous economy and a flourishing of the arts and culture. It was during this period that Zheng He led explorations throughout the world, possibly reaching America. During the early Ming Dynasty China's capital was moved from Nanjing to Beijing. In 1644 Beijing was sacked by a coalition of rebel forces led by Li Zicheng, a minor Ming official turned leader of the peasant revolt. The last Ming Emperor Chongzhen committed suicide when the city fell. The Manchu Qing Dynasty then allied with Ming Dynasty general Wu Sangui and overthrew Li's short-lived Shun Dynasty, and subsequently seized control of Beijing, which became the new capital of the Qing dynasty.
The Qing Dynasty, which lasted until 1912, was the last dynasty in China. In the 19th century the Qing Dynasty adopted a defensive posture towards European imperialism, even though it engaged in imperialistic expansion into Central Asia. At this time China awoke to the significance of the rest of the world, the West in particular. As China opened up to foreign trade and missionary activity, opium produced by British India was forced onto Qing China. Two Opium Wars with Britain weakened the Emperor's control. European imperialism proved to be disastrous for China:
