For most of its 3,500 years of history, China led the world in agriculture, crafts, and science, then fell behind in the 19th century when the Industrial Revolution gave the West clear superiority in military and economic affairs. In the first half of the 20th century, China continued to suffer from major famines, civil unrest, military defeat, and foreign occupation. After World War II, the Communists under MAO Zedong established a dictatorship that, while ensuring China's autonomy, imposed strict controls over all aspects of life and cost the lives of tens of millions of people.
Political controls remain tight at the same time economic controls have been weakening.
Dynastic Period China is the oldest continuous major world civilization, with records dating back about 3,500 years. Successive dynasties developed a system of bureaucratic control which gave the agrarian-based Chinese an advantage over neighboring nomadic and hill cultures. Chinese civilization was further strengthened by the development of a Confucian state ideology and a common written language that bridged the gaps among the country's many local languages and dialects. At great expense in blood and treasure, the Manchus over the next half century gained control of many border areas, including Xinjiang, Yunnan, Tibet, Mongolia, and Taiwan. The success of the early Qing period was based on the combination of Manchu martial prowess and traditional Chinese bureaucratic skills.
