New Institutions and Limited Government
He proclaimed himself Qin emperor, Qin Shi Huangdi, and ruthlessly eliminated his remaining opposition to establish a highly centralized state. Under his leadership a massive road building program was instituted, and the first sections of the Great Wall were built using massive convict labor forces. Convict laborers were plentiful, as even small crimes were punished with extreme severity. Qin Shi Huangdi survived numerous assassination attempts, but most likely had a hand in his own demise. Taoist tradition held that with the proper magical preparations, one could brew the Elixir of Life, a drink which bestowed immortality, and Qin Shi Huangdi abused himself mightily following the instructions of virtually any alchemist who promised to help him cheat death.
When he finally died, his son followed in his equally harsh footsteps. While the sword had brought the Qin to the height of power, it also undid them. A troop of farmers reporting for military service was caught in mountains by winter storms. Rather than report late, where they would have been executed, they became one of the many bands of outlaws that had multiplied in the mountains. But this band was led by an intelligent leader named Liu Bang. He gradually became the focus of anti-Qin sentiment and launched an all out civil war.
He would eventually win, and like all historical accounts it's difficult to determine what happened in the civil war from those records. However, Han Dynasty historians would write that the Qin won every battle of the war except the last. However, their incompetent, harsh rulership alienated their subordinates battle by battle until Liu Bang had gathered all the nobility to his banner. The Qin emperor was murdered and his palace burned down by his few remaining courtiers. Despite being a commoner – in fact he cultivated his common origins in his propaganda – Liu Bang invoked the Mandate of Heaven and was able to declare himself emperor. He took the name Han Gaozu, inaugurating the Han dynasty in 202 BC. These pivotal first two dynasties live on linguistically. The Qin gave their name to the land, China, and the Chinese still call themselves the Han people.
The stories of the civil war show the importance that the teachings of Kung Fu Tzu had taken on; Confucianism decried power for power's sake and taught that moral rulers would naturally command the obedience of their subjects; that people would flock to be ruled by a just ruler in exactly the way Liu Bang's propaganda depict the Qin's vassals switching sides as they fell out of favor with the emperor. The extent to which this was put into practice was always a tense issue, however, the Han emperors surrounded themselves with many men who believed staunchly in the literal truth of it, arguing that the emperor did not need armies to fight the barbarians beyond the Great Wall, but only needed to show them just rulership and they would fall into line. They never won that argument, and the Han emperors were engaged in almost continual wars beyond their borders.
However, just as Cyrus the Great ruled by something more than raw power, the Han emperors acknowledged that they were bound by moral precepts to rule justly. The use of Confucian propaganda and the promotion of many Confucian scholars are demonstrations of the new philosophy's importance at the pinnacle of Chinese power. The Han emperors also used their official power and resources to make many popular Confucian principles into cornerstones of Chinese culture. None pleased the new scholars more then when Han Wu Di, greatest of the Han emperors, created the first Chinese university in 124 BC. The university taught the values and the liberal arts education preferred by the Confucians who filled the ranks of a massive bureaucracy that ran China according to the emperor's wishes.
However, Han Wu Di is best known as a warrior. For hundreds of years, the powerful barbarian tribe known as the Xiongnu had raided China ravaging the northwest and carrying off all the loot they could. On the more practical advice of his anti-Confucian ministers in 120 BC, Han Wu Di began to wage a war of unprecedented scale against them. The barbarian Xiongnu were horseriding nomads of Central Asia, difficult even to engage much less defeat, but Han Wu Di was convinced that only a determined aggressive campaign would secure China's borders. In the end, he was right, though he did not live to see it. The Xiongnu wars would rage almost a hundred years (120 - 36 BC) when large portions of the Xiongnu began breaking away from their homeland. The power of the Chinese army was so great that they decided anywhere else would be better, and they headed west looking for safer pastures. It would be 100 AD before the last Xiongnu were chased out, but these wars were finally successful in driving out the Xiongnu once and for all.
It was one of the most fateful wars of the Ancient Era. It secured the borders of China, but caused intractable problems in other regions as the Xiongnu were not finished in the pages of history. Their steady westward drive (fleeing the Chinese) disrupted other barbarians whom they conquered creating a tidal wave of barbarians steadily rolling west. These were the tribes who crashed into the Roman empire after 250 AD. Then circa 400 AD, the Xiongnu themselves burst into Europe intent on destroying everything in their path. Their leader was called Attila, and the Romans called them the Huns. And while the Huns themselves were unsuccessful in destroying the empire, they ravaged Europe and became the stuff of Roman nightmares. Worse, the waves of Goths, Vandals, Suevi, Alans, etc., etc. which the Han armies had indirectly set in motion proved too much for Rome, precipitating the collapse of Western Europe.
