60th Anniversary Of Communist Party, Beijing, China

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:
The Arrow War (1856–1860) (2nd Opium War) saw another disastrous defeat for China. The subsequent passing of the humiliating Treaty of Tianjin in 1856 and the Beijing Conventions of 1860 opened up more of the country to foreign penetrations and more ports for their vessels. Hong Kong was ceded over to the British. Thus, the "unequal treaties system" was established. Heavy indemnities had to be paid by China, and more territory and control were taken over by the foreigners.
The weakening of the Qing regime, and the apparent humiliation of the unequal treaties in the eyes of the Chinese people had several consequences. One consequence was the Taiping Civil War, which lasted from 1851 to 1862. It was led by Hong Xiuquan, who was partly influenced by an idiosyncratic interpretation of Christianity. Hong believed himself to be the son of God and the younger brother of Jesus. Although the Qing forces were eventually victorious, the civil war was one of the bloodiest in human history, costing at least 20 million lives (more than the total number of fatalities in the World War I), with some estimates of up to two hundred million. Other costly rebellions followed the Taiping Rebellion, such as the Punti-Hakka Clan Wars (1855–67), Nien Rebellion (1851–1868), Muslim Rebellion (1862–77), Panthay Rebellion (1856–1873) and the Miao Rebellion (1854–73).
