Context: The Qin dynasty was the first dynasty of Imperial China, lasting from 221 to 206 BC. Named for its heartland of Qin, in modern-day Gansu and Shaanxi, the dynasty was formed after the conquest of six other states by the Qin state, and its founding emperor named Qin Shi Huang, the First Emperor of Qin. The strength of the Qin state was greatly increased by the Legalist reforms of Shang Yang in the fourth century BC, during the Warring States period. In the mid and late third century BC, the Qin accomplished a series of swift conquests, first ending the powerless Zhou dynasty, and eventually conquering the other six of the Seven Warring States to gain control over the whole of China. It is also the shortest dynasty in Chinese history, lasting only 15 years with two emperors., Ziying (died January 206BC) was the third and last emperor of the Qin dynasty. He ruled over a fragmented Qin Empire for 46 days from mid-October to early December in 207BC., The Zhou dynasty was a Chinese dynasty that followed the Shang dynasty and preceded the Qin dynasty. Although the Zhou dynasty lasted longer than any other dynasty in Chinese history, the actual political and military control of China by the dynasty, surnamed Ji, lasted only until 771 BC, a period known as the Western Zhou., Qin Shi Huang (18 February 25910 September 210) was the founder of the Qin dynasty and was the first emperor of a unified China. He was born Ying Zheng or Zhao Zheng, a prince of the state of Qin. He became the King Zheng of Qin when he was thirteen, then China's first emperor when he was 38 after the Qin had conquered all of the other Warring States and unified all of China in 221 BC. Rather than maintain the title of "king" borne by the previous Shang and Zhou rulers, he ruled as the First Emperor of the Qin dynasty from 220 to 210 BC. His self-invented title "emperor" (""), as indicated by his use of the word "First", would continue to be borne by Chinese rulers for the next two millennia., The Warring States period was an era in ancient Chinese history following the Spring and Autumn period and concluding with the Qin wars of conquest that saw the annexation of all other contender states, which ultimately led to the Qin state's victory in 221 BC as the first unified Chinese empire known as the Qin dynasty. Although different scholars point toward different dates ranging from 481 BC to 403 BC as the true beginning of the Warring States, Sima Qian's choice of 475 BC is generally the most often cited and popularly accepted one. The Warring States era also overlaps with the second half of the Eastern Zhou dynasty, though the Chinese sovereign, known as the king of Zhou, ruled merely as a figurehead and served as a backdrop against the machinations of the warring states., The Second Emperor of Qin (229  October 207 BCE) was the son of Qin Shi Huang and the second emperor of China's Qin dynasty. He ruled from 210 to 207 BCE., Zhao Gao ( Simplified Chinese  , died 207 BC ) was a Chinese politician of the Qin dynasty . Allegedly a eunuch , he served as a close aide to all three emperors of the Qin dynasty -- Qin Shi Huang , Qin Er Shi and Ziying -- and was regarded as having played an instrumental role in the downfall of the dynasty . Zhao Gao started his career under Qin Shi Huang as a zhongche fuling (  ) , an official in charge of managing the palace horse - drawn carriages . During this period of time , he also served as an attendant to Huhai , Qin Shi Huang 's youngest son , and tutored him in the laws of the Qin Empire . In 210 BC , after Qin Shi Huang died in Shaqiu (  ; south of present - day Dapingtai Village , Guangzong County , Hebei ) , Zhao Gao and Li Si , the Chancellor , secretly changed the emperor 's final edict , which named Fusu , the crown prince , the heir to the throne . In the falsified edict , Fusu was ordered to commit suicide while Huhai was named the new emperor . After Huhai was enthroned as Qin Er Shi , he promoted Zhao Gao to langzhongling (  ) , an official post whose duties included managing the daily activities in the imperial palace . Zhao Gao , who was highly trusted by Qin Er Shi , instigated the emperor to exterminate his own siblings to consolidate power , and used the opportunity to eliminate his political opponents such as Meng Tian and Meng Yi . He also framed Li Si for treason and had Li and his entire family executed , after which he replaced Li as the Chancellor and monopolised state power . In 207 BC , when rebellions broke out in the lands east of Hangu Pass , Zhao Gao became worried that Qin Er Shi would blame him , so he launched a coup in Wangyi Palace (  ; in Xianyang , near present - day Xi'an , Shaanxi ) and assassinated the emperor . Following Qin Er Shi 's death , Zhao Gao installed Ziying , Fusu 's son , on the throne . Ziying sent Han Tan (  ) , a eunuch , to assassinate Zhao Gao ., Shaanxi, formerly romanized as Shensi, is a province of the People's Republic of China. Officially part of the Northwest China region, it lies in central China, bordering the provinces of Shanxi (NE, E), Henan (E), Hubei (SE), Chongqing (S), Sichuan (SW), Gansu (W), Ningxia (NW), and Inner Mongolia (N). It covers an area of over with about 37 million people. Xi'anwhich includes the sites of the former Chinese capitals Fenghao and Chang'anis the provincial capital. Xianyang, which served as the Qin capital, is located nearby. The other prefecture-level cities into which the province is divided are Ankang, Baoji, Hanzhong, Shangluo, Tongchuan, Weinan, Yan'an and Yulin., Shang Yang (390338 BCE, born Wei Yang in the State of Wei) was an important Chinese statesman of the State of Qin during the Warring States period. His policies laid the foundation that enabled Qin to conquer all of China, uniting the country for the first time and ushering in the Qin dynasty. He and his followers contributed to the Book of Lord Shang strain of what has modernly been termed Chinese Legalism., Subject: zhao gao, Relation: date_of_death, Options: (A) 15 (B) 18 (C) 206 (D) 207 (E) 207 bce (F) 210 (G) 221 (H) 229 (I) 338 (J) 37 (K) 38 (L) 390 (M) 403 (N) 46 (O) 475 (P) 771
