Around 220 BC
Having unified the warring states, Chin became emperor of a unified China in 221 B.C. His rule as emperor had lasted for 12 years when he died at the age of 49. When he died, his body was covered by fish to disguise the odor and to delay news until his body arrived back home -- according to legend. China Unified: With the defeat of the other six warring states, Qin Shi Huang had unified northern China. His army would continue to expand the Qin Empire's southern boundaries throughout his lifetime, driving as far south as what is now Vietnam. The king of Qin became the Emperor of Qin China. As emperor, Qin Shi Huang reorganized the bureaucracy, abolishing the existing nobility and replacing them with his appointed officials. He also built a network of roads, with the capital of Xianyang at the hub. The baby, born in Hanan, was named Ying Zheng. The prince believed the baby was his own. Ying Zheng became king of the Qin state in 246 BCE, upon the death of his supposed father. He ruled as Qin Shi Huang, and unified China for the first time. Qin Shi Huang (then known as Ying Zheng) became the King of Qin at the age of 13 but did not assume control until he was 22. He was the one responsible for unifying china. Qin Shi Huang assumed autocratic control, introducing a new currency, and by creating a unified system of weights and measures, writing and currency. Confidence votes 2. On January 1, 1912 the Republic of China was created that unified mainland China and then in 1949 united Taiwan and other islands off the mainland. Qin Shi Huang (or Shi Huangdi) was the First Emperor of a unified China, who ruled from 246 BCE to 210 BCE. In his 35-year reign, he managed to create magnificent and enormous construction projects. He also caused both incredible cultural and intellectual growth, and much destruction within China. Until Qin Shi Huang became the first emperor around 220 BC and unified China under a centralised system, there was no such thing as a Chinese national architecture. Under Qin Shi Huang’s rule large and impressively decorated structures were built.
