221–206 BCE
Qin unification and the First Emperor
A short-lived empire standardized writing and measures and left an extraordinary tomb.
Turning conquest into administration
Defeating six states did not ensure lasting rule. Qin linked commanderies and counties to appointed officials under the emperor, connecting taxation, supply and military authority with the center. This administrative approach outlasted the short dynasty.
Standardizing records, money and roads
Different weights and currencies complicated trade and collection. Standardization reduced conversion, while shared script aided official records. This did not make every spoken language identical overnight.
Standardized records aided administration, while book burning in 213 BCE reveals control over knowledge. Common formats and limits on permissible content were different effects of central power.
The legacy of a short dynasty
Roads and standards aided government, while walls and the imperial tomb demanded labor. Terracotta soldiers were one part of that project. Qin fell quickly, but administrative practices outlasted it, carrying different benefits and burdens.
Excavated figures form part of a larger mausoleum plan. The central chamber remains unexcavated; recorded mercury rivers are not directly observed structures. Different evidence informs figures and the overall plan.
