Significant Achievement:  Unified China

  The Qin came to power in 221 B.C. after conquering the warring states.  Throughout this dynasty, many changes  were made to unify China.  A Legalist form of government was implemented to rule the people.   The language and writing systems that had varied from area to area during the Warring States period were standardized.   This was done to improve communication across the country.  Currency, measurements, and axle lengths were also standardized.   Many public works projects were performed to improve travel, farming, and security.
