Brief introduction to history
First of all, a brief history
Xi, Athens, Rome and Cairo are also called the four ancient capitals in the world. From BC 1 1 century to AD1century, there were 13 dynasties or regimes that established their capitals and regimes in Xi 'an, which lasted for more than 1 100 years.
From about 1 1 century BC to the end of 9th century AD, Ann was the political, economic and cultural center of ancient China for a long time, and was always under the jurisdiction of local administrative organs-Zhou, County, Fu, Lu, Province and Chang 'an and Xianning counties. In most dynasties, Xi 'an was subordinate to Jingzhao Prefecture (county), which was a county-level organizational system. In the Yuan Dynasty, Jingzhao was changed to Anxi Road (later changed to Fengyuan Road). In the second year of Hongwu in the Ming Dynasty (AD 1369), Fengyuan Road was abandoned and xi Anfu was established, hence the name An. 1928 was first established as a city in Xi, and 1948 was changed from a provincial city to a city under the jurisdiction of the Executive Yuan of the National Government.
After the founding of People's Republic of China (PRC), Xi 'an was once a city under the jurisdiction of the Shaanxi-Gansu-Ningxia Border Region, a city under the jurisdiction of the Northwest Administrative Region, a municipality directly under the Central Government and a city under separate state planning. Since 1954, Xi 'an has been the capital of Shaanxi Province, and now it is a sub-provincial city, with jurisdiction over nine districts and four counties. 198 1 year, UNESCO recognized Xi as a world famous historical city.
Second, the dynasty of Xi 'an with its capital.
In the history of China, 20 regimes once established their capitals in Xi 'an. But which of them should be called dynasty and whose capital should be regarded as Xi 'an is a controversial issue. This is the different understanding of the concepts of "Korea", "capital" and "capital", which leads to the different understanding of which dynasty's capital is in a certain place. At present, the official statement is 13 dynasty. There are four different opinions: 10, 1 1, 12, 14, 17. Among them, there are two versions of 14 dynasty and 17 dynasty.
10 Super Master
10 dynasty-in chronological order: western Zhou dynasty (363 BC), Qin dynasty (0/5 BC), western Han dynasty (2 10 BC), former Zhao dynasty (0/65438 BC) and former Qin dynasty (33 BC)
1 1 chaoshuo
1 1 dynasty-On the basis of 10 dynasty, Wang Mang established a new dynasty (before 15).
12 Super Master
12 dynasty-On the basis of 1 1 dynasty, the Western Jin Dynasty (Yu 4 years) was added.
13 Super Master
13 dynasty-On the basis of 12 dynasty, the Eastern Han Dynasty was added (6 years in Xian Di).
14 Super Master
14 dynasty-there are two situations: (1) adding Daxia dynasty on the basis of 13 dynasty; (2) Wu Zhou founded by Wu Zetian joined the 13 dynasty (15).
16 Super Master
16 dynasty-On the basis of 13 dynasty, the regime established by Liu Xuan was re-established, and the red eyebrow regime established by Fan Chong and Liu Pengzi and the Daqi regime established by Huang Chao were added.
17 Super Master
17 super-divided into two cases: (1) On the basis of 65438 super-1 case, add Dashun established by Wu Zhou, Daqi and Li Zicheng; (2) On the basis of the 13 dynasty, a new initial regime, the Chimei regime, was established, and He Daqi Dashun was established.
Third, the relationship between Xianyang and Chang 'an in history
Historically, Xi and Xianyang belong to the same city today. This can be seen from the relationship between Xianyang and Chang 'an in ancient times. Xi and Xianyang are the nearest cities in China, less than 20 kilometers. At the same time, Xianyang built the West Third Ring Road in Xi 'an, and the airport moved from Taoyuan in Xi 'an to Xianyang. In 2006, Xianyang area code was merged into Xi 'an, and 029 area code was used together with Xi 'an.
Qin dynasty
The capital is Xianyang. Epang Palace is located in a large area of Xi 'an today, and the Terracotta Warriors and Mausoleums are located in Xi 'an today. The ancestral temple of Qin was on the south bank of Weihe River, and Jing Ke stabbed the king of Qin, which happened in Qinzhangtai Palace (later the front hall of Han Weiyang Palace). Lin Xiangru, Lian Po and the king of Qin sat on the stage. The layout of palaces in Qin dynasty has not yet formed the layout of Miyagi, Imperial City and Three Great Halls. Xianyang City, Qin Dynasty spans the Weihe River north and south.
Han (HA)
The capital is Chang 'an. Chang 'an in Han Dynasty was founded on the site of Xianyang in Qin Dynasty. According to historical records, "Chang 'an in Han Dynasty is also the site of Xianyang in Qin Dynasty", Zhang Heng's Xijing Fu says that Chang 'an in the Western Han Dynasty "crossed the Zhou Dynasty to explore the Qin system", and Huang Tu's Preface to Three Fu also says: "Wu Zhao governs Xianyang and takes Han as its capital". "Old Tang Book Geography" said: "The capital is Xianyang, Qin and Chang 'an, Han. "After King Qin Huiwen, Xianyang continued to expand to the south, and built buildings such as Zhangtai, Xingle Palace, Ganquan Palace, Xin Palace, Epang Palace and Seven Temples in the south of Weihe River. After Liu Bang won the world, under the persuasion of Lou Jing and Sean, he built Chang 'an as his capital. Restoration of Xingle Palace in Qin Dynasty was changed to Changle Palace, and Weiyang Palace was built on the basis of Qin Zhangtai. That is to say, Chang 'an City in Han Dynasty was established on the basis of Xianyang, Qin Dou, indicating that the location of the capital was determined by Han Dynasty and Qin Dynasty. The Ques Palace in the Han Dynasty is located in Xi 'an Hancheng Reserve, north of the North Second Ring Road, and the mausoleum of Emperor Jingdi of the Han Dynasty is located in Xianyang.
College teachers
The capital is Chang 'an. Miyagi coincides with Xi 'an today, and the palace coincides with Xi 'an Ming City Wall today. Most of the imperial tombs in the Tang Dynasty, such as Zhaoling Ganling, are located in Xianyang City today. The eighteen tombs in the Tang Dynasty were all in the county under the jurisdiction of Jingzhao Prefecture, and Ganling was Fengtian County of Jingzhao Prefecture.
People's Republic of China (PRC)
Xi and Xianyang belong to the same city and were divided into two cities in 1950' s: Xi and Xianyang. Xi is the deputy provincial level, and Xianyang is the prefecture level.
