WORLD HISTORY

Detailed explanation-1: -Qin Shi Huangdi, the first Qin Emperor, was a brutal ruler who unified ancient China and laid the foundation for the Great Wall.

Detailed explanation-2: -Ying Zheng, the king of Qin unifies China and proclaims himself the First Emperor, as he is the first Chinese sovereign able to rule the whole country, thus ending the Warring States period. He is known by historians as Qin Shi Huang.

Detailed explanation-3: -Qin Shi Huang was the first Chinese sovereign to proclaim himself “Emperor", after unifying China in 221 BC. That year is therefore generally taken by historians to be the start of the “Qin dynasty” which lasted for fifteen years until 207 when it was cut short by civil wars.

Detailed explanation-4: -Qin Shi Huang began a militarily-driven expansionist policy. In 229 B.C., the Qin seized Zhao territory and continued until they seized all five Zhou states to create a unified Chinese empire in 221 B.C.

Detailed explanation-5: -Those harsh methods, combined with the huge tax levies needed to pay for the construction projects and wars, took their toll, and rebellion erupted after Shihuangdi’s death in 210 bce. In 207 the dynasty was overthrown and, after a short transitional period, was replaced by the Han dynasty (206 bce–220 ce).
