<P> The Qin dynasty ( Chinese : 秦 朝 ; pinyin : Qín Cháo ; Wade -- Giles : Ch'in Ch'ao ) was the first dynasty of Imperial China , lasting from 221 to 206 BC . 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>
