context_page_description: The recorded military history of China extends from about 2200 BC to the present day. Although traditional Chinese Confucian philosophy favored peaceful political solutions and showed contempt for brute military force, the military was influential in most Chinese states. Chinese pioneered the use of crossbows, advanced metallurgical standardization for arms and armor, early gunpowder weapons, and other advanced weapons, but also adopted nomadic cavalry and Western military technology. China's armies also benefited from an advanced logistics system as well as a rich strategic tradition, beginning with Sun Tzu's The Art of War, that deeply influenced military thought.
context_section_description: In 221 BC, the Qin unified China and ushered in the Imperial Era of Chinese history. Although it only lasted 15 years, Qin established institutions that would last for millennia. Qin Shi Huan, titling himself as the "First Emperor", standardized writing systems, weights, coinage, and even the axle lengths of carts. To reduce the chance of rebellion, he made the private possession of weapons illegal. In order to increase the rapid deployment of troops, thousands of miles of roads were built, along with canals that allowed boats to travel long distances. For the rest of Chinese history, a centralized empire was the norm.
  During the Qin dynasty and its successor, the Han, the Chinese armies were faced with a new military threat, that of nomadic confederations such as the Xiongnu in the North. These nomads were fast horse archers who had a significant mobility advantage over the settled nations to the South. In order to counter this threat, the Chinese built the Great Wall as a barrier to these nomadic incursions, and also used diplomacy and bribes to preserve peace. Although the Qin general Meng Tian ousted the Xiong-nu from the Ordos region, they regained power under the rule of Maodun. Maodun conquered the Eastern Hu and drove the Yuezhi tribes west. He reclaimed the Ordos from the now crumbling Qin empire and defeated the first Han emperor Gao in battle. This led to a policy of appeasement until the reign of Wudi of Han, who decided to take a tougher stance. However, protecting the borders required a significant investment. Manning the stations of the Great Wall took about ten thousand men. To support them, fifty to sixty thousand soldier-farmers were moved to the frontiers in order to reduce the cost of transporting supplies. These drafted farmers were not good cavalry troops, so a professional army emerged on the frontiers. These consisted of northern Han mercenaries, convicts working for their freedom, and subjected "Southern" Xiong-nu living within Han territory. By 31 BC, the Han dynasty abolished universal military conscription that was passed down from the Warring States. In the South, China's territory was roughly doubled as the Chinese conquered much of what is now Southern China, and extended the frontier from the Yangtze to Vietnam.
  Armies during the Qin and Han dynasties largely inherited their institutions from the earlier Warring States Period, with the major exception that cavalry forces were becoming more and more important, due to the threat of the Xiongnu. Under Emperor Wu of Han, the Chinese launched a series of massive cavalry expeditions against the Xiongnu, defeating them and conquering much of what is now Northern China, Western China, Mongolia, Central Asia, and Korea. After these victories, Chinese armies were tasked with the goal of holding the new territories against incursions and revolts by peoples such as the Qiang, Xianbei and Xiongnu who had come under Chinese rule.
  The structure of the army also changed in this period. While the Qin had utilized a conscript army, by Eastern Han, the army was made up largely of volunteers and conscription could be avoided by paying a fee. Those who presented the government with supplies, horses, or slaves were also exempted from conscription.
