Named for its heartland of Qin, in modern - day Gansu and Shaanxi, the dynasty was founded by the Qin state and its founding emperor took the title Qin Shi Huang, the First Emperor of Qin . The strength of the Qin state was greatly increased by the "Legalist" reforms of Shang Yang in the fourth century BC, during the Warring States period . In the mid and late third century BC, the Qin state carried out a series of swift conquests, first ending the powerless Zhou dynasty, and eventually conquering the other six of the Seven Warring States . It is the shortest major dynasty in Chinese history, lasting only 15 years with two emperors, but the imperial system it inaugurated lasted, with interruptions and adaptation, until 1911 . </P> <P> The Qin sought to create an imperial state unified by structured political power and a stable economy able to support a large military . The central government moved to undercut aristocrats and landowners and have direct administrative control over the peasantry, who comprised the overwhelming majority of the population, and control over whom would grant the Qin a large labor force . This allowed ambitious projects, such as connecting walls on the northern border, forerunners of the Great Wall of China . Three hundred thousand peasants and convicts were forced to work on this project . The Qin introduced a range of reforms to unify their realm and promote commerce: standardized currency, weights and measures, and a uniform system of writing . The Qin's military used the most recent weaponry, transportation, and tactics, though the government was heavy - handed and bureaucratic . Yet scholars now argue that the dynasty was far from the monolithic tyranny portrayed by Han dynasty Confucians . There was indeed an attempt to restrict criticism and purge traces of old dynasties, but not the supposed burning of books and burying of scholars later alleged . Recently excavated Qin texts show a more pragmatic and eclectic approach than a reading of traditional accounts would suggest . Qin administration was by no means purely punitive, and was no harsher than was prevalent at the time . The Qin were not doctrinaire . Confucianism and its values coexisted with Legalism during the reign of the First Emperor . </P>
