Answer:The Qin Dynasty established the first empire in China, starting with efforts in 230 B.C., during which the Qin leaders engulfed six Zhou Dynasty states. The empire existed only briefly from 221 to 206 B.C., but the Qin Dynasty had a lasting cultural impact on the dynasties that followed.
Capital of Qin Dynasty
The Qin region was located in modern-day Shaanxi province, north of the Zhou Dynasty territory - Qin served as a barrier between it and the less civilized states above it. The capital of the Qin Dynasty was Xianyang, which was extensively enlarged after Qin dominance was established.
Qin itself had been considered a backwards, barbarian state by the ruling Zhou Dynasty. This distinction had to do with its slow pace in embracing Chinese culture, for instance, lagging behind the Zhou in doing away with human sacrifice.
The ruling class of Qin nonetheless believed themselves to be legitimate heirs to the Zhou states, and through the centuries they strengthened their diplomatic and political standing through a variety of means, including marriage.
Shang Yang
It was during the rule of Duke Xiao from 361 to 338 B.C. that the groundwork was laid for conquest, primarily through the work of Shang Yang, an administrator from the state of Wey who was appointed Chancellor.
Shang Yang was a vigorous reformer, systematically reworking the social order of Qin society, eventually creating a massive, complicated bureaucratic state and advocating for the unification of Chinese states.
