Today, the ancestors of the Yi and Bai nationalities are

Up to now, the ethnic origin of the Yi people is mainly the aboriginal theory and the Qiang border theory.

The arguments put forward by the aborigines are quite sufficient. It can be divided into two kinds: southwest nativism and Yunnan nativism. According to the theory of southwest aborigines, the Yi people have lived in the southwest of the motherland since ancient times, and after different stages of human development, they have become the Yi people today. This claim is based not only on China literature, but also on ancient Yi literature, myths and legends. According to the theory of Yunnan aborigines, Yunnan is the origin of Yi people.

Bian Qiang said that the ancient Qiang people who lived in Hehuang area in northwest China six or seven thousand years ago began to develop in all directions, and one of them swam to the southwest of the motherland. The early southern branch of the ancient Qiang people merged with the local indigenous tribes, and later Qiongfan in Xichang and Fan Dian in Yunnan were the ancestors of the Yi people.

3000 years ago, the Yi people were widely distributed in the southwest of China, that is, the so-called tribes such as Song Yue Yi, Wuyi, Kunming, Laojin, Momo and Pu, which often appeared in history books.

The Han Dynasty called it "Southwest Yi".

Since the Sui and Tang Dynasties, there have been two kinds of barbarians in the areas of Yi ancestors, and they have merged with other ethnic groups.

During the long-term formation and development of Yi ancestors, their activities once spread all over the central areas of Yunnan, Sichuan and Guizhou provinces and a part of Guangxi, and their core areas should be the vast areas adjacent to the three provinces.

Bai nationality:

More than 4,000 years ago, in the Neolithic Age, the ancestors of the Bai nationality thrived in the area centered on Cangshan Erhai Lake and Dianchi Lake, created the early rice culture on the platform by the river, and lived a nomadic life of farming, fishing and hunting. Roughly equivalent to the Warring States period, the first kingdom of the Bai nationality-Baizi Kingdom (also known as Baiguo) was formed. From the Spring and Autumn Period to the early Tang Dynasty, the foreign trade exchanges of Bai ancestors began to take shape. Huaxia civilization and ancient Indian civilization spread to Erhai Lake area one after another. Bai ancestors kept learning from them and initially formed a Bai culture with Sanskrit/Chinese characteristics. Kun, East (West) Hull people, Qulian imperial edict, Mengbi imperial edict, Yueyan imperial edict, Langqiong imperial edict, Shi Lang imperial edict and Mengshe imperial edict successively surrendered to the State of Bai Zi.

In the third year of Zhenguan in Tang Dynasty (AD 629), the white country was weak, and Zhang Qiuchan was located in Nuluo, and the main imperial edict was Meng Luxury. In 737 AD, the imperial envoys of the Tang Dynasty solemnly assisted Nanzhao in capturing Shihecheng (now Fengyi) and Shiqiao (now Shimonoseki), occupying Taihe and attacking Heman, and then continued to annex the imperial edicts. In the 26th year of Kaiyuan (738), with the support of the Tang Dynasty, Pirog merged five imperial edicts and became the king of Yunnan. He established political power based on Xi Erhai Lake (now Erhai Lake) and took his surname as the country name, which was called Dameng. The following year, he moved the capital to Taihe City (now Dali). The history of the Central Plains is called Nanzhao, and the Tubo is called Jiang Yu.

In 897, Zheng Maisi, an official of Qing Dynasty, ordered Deng Yang, a trusted minister of Montessori in Nanzhao, to kill Long Shun, the emperor of Nanzhao. In 902, after the death of Shun Huazhen, the son of Changshun, the son of Shun Huazhen was killed for eight months, and there were more than 800 relatives of the Mongols, and the Nanzhao of the Mongols perished. Zheng Maisi founded Dachang and Guo, calling himself the emperor. He died in 909, and the temple was named Sage. His posthumous title was the emperor Ming Sheng Wu Wen Wei Dehuan. His son Zheng Renmin succeeded to the throne.

In 928 AD, Gong Huidi Zheng Longqiu was killed by Yang Ganzhen, the minister of Dongchuan, and made Zhao Shanzheng, the official of Qingping (the prime minister), king, and changed his country name to "the country of Daxing" and Xingyuan. Zhao Shanzheng mourned for Condi, and his title was sacred. The country of Dachang perished. In 929, Yang Ganzhen succeeded Zhao Shanzheng, established the principle of justice, reformed the Yuan Dynasty and advocated saints. Brother Yang Zhao refers to Duan Siping as the emperor. In doubt, Yang Gan was really anxious to kill Duan Siping. During being hunted by Yang Ganzhen, Duan Siping was inspired by the divination of Xiushan Shrine and hid in the tribe sentenced by his uncle. Good officials are closely related to Duan Siping, and Duan Siping's younger brother Duan Siliang and his strategist Dong Jialuo are sent to protect them. In 930 AD, Yang Ganzhen's position was usurped by his younger brother Yang Zhao. After Yang Zhao acceded to the throne, he changed to Yuan Daming. Duan Siping borrowed thirty-seven barbarian soldiers from Dongwu to attack Yanggan Town in Shicheng, and took Dong Jialuo as his strategist to attack Dali in all directions. At that time, Yang Zhao and Chen Bing were under the bridge, but Duan Jun could not pass. Duan Siping had three dreams in his sleep that night: "People have no heads; Jade bottle has no ears; Second time around ",puzzled by this, his strategist Dong Jialuo pointed out that Duan Siping's dream is a big omen, because" you are a husband, and you have to go to the first day; Jade bottle goes to the ear to be king; If there is no suitable person in second time around, the morale of the army will be greatly boosted. On that day, Duan Jun found a woman engaged in yarn washing and guided Duan Jun to a place suitable for the army to cross the river. He said, "People come from the end of my river and horses come from Sansha. My country is called Dali. Duan Siping's army successfully crossed the river according to the instructions of the yarn washer. Yang Zhao committed suicide after losing the war. After learning the news of defeat, Yang Ganzhen abandoned the city and fled, and was captured by Duan Siping Army. When Duan Siping acceded to the throne, he established Dali, established Yuan Wende, and still made Dali his capital. Over 500 years.

Dali was destroyed by Mongolia in 1253. The Yuan Dynasty established Yunnan Province on the original Dali border. The Yuan Dynasty appointed Duan Xingzhi, the last surrendered Dali emperor, as the "General Manager of Dali" and succeeded him. General manager of Dali kingdom at the end of Yuan Dynasty passed down 1 1. In 138 1 year, the Ming army pacified Yunnan and cancelled Duan's hereditary privilege in Dali. During the Yuan, Ming and Qing Dynasties, the Bai nationality gradually formed an organic whole with the Central Plains in politics, economy and culture.
