The Shang, found in 1600 BC, was China's first fully historical dynasty. It was a Bronze Age culture. Iron replaced bronze around 600 BC. Successive dynasties developed a system of bureaucratic control that 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. Whenever China was conquered by nomadic tribes, as it was by the Mongols in the 13th century, the conquerors sooner or later adopted the ways of the "higher" Chinese civilization and staffed the bureaucracy with Chinese.

When the Chinese discovered [[gunpowder]] they had no intention of using it as a weapon. Instead, it was developed in the Tang dynasty as a formula for immortality by religious Daoist alchemists.  It was discovered to be a powerful explosive, and when lit, gunpowder in a bamboo stick made a colorful explosion. This loud explosion was used to chase away evil spirits and to celebrate weddings, victories in battles, and religious ceremonies. However, contrary to popular belief, the first depiction of gunpowder in pictorial form shows it in military use. Similarly, it is also known that before the arrival of Westerners in China, Chinese troops were equipped with firearms.
