The Qin dynasty surfaced during China’s Warring States period. This era spanned 250 years—475 B.C. to 221 B.C. During the Warring States period, the city-state kingdoms of ancient China’s Spring and Autumn period consolidated into larger territories. The feudal states fought each other for power during this era characterized by advances in military technology as well as education, thanks to the influences of Confucian philosophers.
The Qin dynasty came to prominence as the new imperial dynasty (221-206/207 B.C.) after conquering rival kingdoms and when its first emperor, the absolute monarch Qin Shi Huang (Shi Huangdi or Shih Huang-ti) unified China.
