Xi'an had many names in ancient times, and "Chang'an" was just the most famous and longest-lasting one among them. The name "Chang'an" is related to Liu Bang (256 BC - 195 BC), the founder of the Han Dynasty. It means "long-lasting peace and stability" and eternal peace in the world.
In the last years of the Qin Dynasty, Hu Hai, the second emperor of the Qin Dynasty, was debauched and immoral, leaving the people living in dire straits and making people all over the country panic. In 209 BC, the rebel army led by Chen Sheng and Wu Guang quickly rose up in Daze Township in Suzhou, Anhui, and dealt a heavy blow to the Qin Dynasty.
At this time, Liu Bang, who was the county magistrate of Peixian County in Xuzhou, Jiangsu Province, saw that the Qin Dynasty was over, so he gathered more than 3,000 people in Peixian County, organized an uprising team, and began to attack Qin Dynasty, and occupied Peixian County, and at the same time took refuge in Xiang Liang, who was more powerful than him and was also Xiang Yu's uncle, and was entrusted with important tasks.
Liu Bang's rebel army went all the way north and attacked Xianyang, the capital of Qin Dynasty. By 206 BC, Liu Bang's army invaded Guanzhong, Shaanxi. At this time, the prince of Qin Dynasty saw that the situation was over and surrendered to Liu Bang. The Qin Dynasty also perished immediately, and Liu Bang became the local emperor of Guanzhong.
At this time, Xiang Yu also became stronger, and a group of troops more powerful than Liu Bang gathered around him. When Xiang Yu saw Liu Bang getting stronger and stronger, he was worried that it would pose a threat to himself, so he decided to get rid of Liu Bang. Therefore, the famous "Hongmen Banquet" in history happened immediately. In the end, Liu Bang escaped from death at the Hongmen Banquet and fled to the Hanzhong area of ??Shaanxi Province, where he became the "King of Han". But both Xiang Yu and Liu Bang regarded each other as a thorn in the other's side, and they were both waiting for the opportunity to get rid of them.
Soon, the struggle between Chu and Han began. After a hard battle, Liu Bang became the final winner and unified the world.
After Liu Bang gained power, in 202 BC, he moved the capital from Yueyang in the north of the Wei River to Haojing in the south of the Wei River, and proclaimed himself emperor here. From then on, another A new dynasty, the Western Han Dynasty, followed. Liu Bang experienced the troubled life in the last years of the Qin Dynasty and fought with Xiang Yu for a long time before he gained the kingdom. It was not easy to gain the kingdom. Therefore, he hoped that his country could last forever and have long-term peace and stability. Therefore, he named the capital "Chang'an".
