The Dai people's struggle against imperialism and feudalism in modern times.

In the middle and late period of A.D. 1 century, Daguang Kingdom was squeezed by the Han Dynasty and forced to move its capital from east to west of Nujiang River, and the territory east of Nujiang River was occupied by the Han Dynasty. The Dai ancestors were divided into two parts by the Nujiang River. The Dai ancestors to the west of the Nujiang River were loyal to Daguang, and the Dai ancestors to the east of the Nujiang River became subjects of the Han Dynasty. In the following years, the Daguang regime, which moved westward, continued to expand southward, and once again rose and ruled the Irrawaddy River basin, which was called "Shan State" by the Han Dynasty. In order to avoid the further suppression of the Han Dynasty (Eastern Han Dynasty), Daguang (Shaanxi) chose to make friends with the Han Dynasty, and the Han Dynasty also made a friendly response, which strengthened the relations between the two countries.

At the beginning of the third century, Daguang Kingdom moved south of Wangcheng to Bagan (present-day Myanmar) in the middle reaches of Irrawaddy River to resist the invasion of Sui people. In the following hundreds of years, the influence of the Dai people spread southward, and many tribes in the Irrawaddy River basin were annexed by the Daguang (Shan) Kingdom.

In the middle of the 6th century, Daguang (Mountain) was captured by the troops of Qi State, and the Daguang (Mountain) regime collapsed. The Hunlu and Hunlai brothers in the north of Daguang (Mountain) organized the Dai army and civilians to resist the invasion of Qi in Mengmao (Ruili), and at the same time unified the Dai ministries and created another Dai regime-Guo Qian Zhan Bi Kingdom.

In the 7th century AD, the Dai people in the west of Nujiang River became stronger and stronger under the rule of Guo Zhanbi. After the Han forces withdrew from the Central Plains, the Dai people east of the Nujiang River also formed ten states, including Mengshe (Nanzhao) and Li Meng.

In the 8th century A.D., Mengshe (Nanzhao), a small Dai country in the south of Erhai Lake, annexed other small countries in Erhai Lake through war, and then annexed the former kingdom of Guo Zhan, west of Nujiang River, and the large and small tribes on Yunnan-Guizhou Plateau, and established a multi-ethnic country with Dai as the main body. Dai forces began to extend to every corner of Yunnan-Guizhou Plateau. The powerful Nanzhao combined the Tang Dynasty and the Tubo War for hundreds of years, which objectively promoted the development of Dai politics, military affairs, culture and other fields.

After the tenth century, the ancestors of the Dai people lost the Mengshe (Nanzhao) regime, and the ministries of the Dai people fell apart. The ancestors of the Dai people near Erhai Lake were ruled by the Dali State established by the Heman people (the ancestors of the Bai people). Dai ancestors far away from Erhai Lake are constantly harassed by foreigners, Dai people in the middle and lower reaches of Nujiang River and Irrawaddy River are constantly harassed by Burmese people, and Dai people in the middle and lower reaches of Lancang River are under Mongolian rule.

In the middle of 10 century, the Dai people in Irrawaddy River and Nujiang River valley, under the leadership of the former Chambi royal family, restored the State Chambi Kingdom (later Chambi Kingdom).

At the beginning of12nd century, the leader of the Dai nationality in Mengshe led the Dai army and civilians to fight against the Mongols, unified the Dai ministries in the Lancang River basin, and established the kingdom of Jinghong Meng Ling from Dali.

In the middle of13rd century, Mongolian troops invaded Dai areas, resulting in the occupied kingdom and Monroe kingdom being occupied by Mongolian troops one after another, which led to a large number of Dai people moving to the south and west, indirectly enhancing the strength of small Dai countries in the south and west. The kingdom ruled by Ahong has covered a large area of northeast India today; Lanna's ruling kingdom invaded northwest Thailand and northeast Myanmar, Sukhothai's ruling kingdom invaded central and northern Thailand, and the Dai people in northern Myanmar also controlled the Bagan kingdom established by the Burmese people and became the actual rulers in central and northern Myanmar.

In the14th century, the Dai people in Mengmao broke away from the Mongols and established Luquan Kingdom, and gradually gained advantages in the war with the Mongols, unifying the vast areas of western Yunnan, southwestern Yunnan and northwestern Myanmar. The Dai prince in Luang Prabang unified most of Laos today with the help of Khmer army. After the division of the Dai people who controlled the Bagan Kingdom, they were reunited and established the Awa Kingdom which ruled the central and northern parts of Myanmar. After the decline of Mongols, the Kingdom of Meng Ling also resumed its rule over southern Yunnan, northern Laos and northeastern Myanmar. The founding monarch of Lu Chuanguo thought of sweating.

From15th century to16th century, the Dai regime began to weaken. Han and Ming Dynasties sent troops to Luchuan Kingdom for three times, and Xu Dong Kingdom of Myanmar successively annexed Awa Kingdom, Lanna Kingdom, Lancang Kingdom, Meng Ling Kingdom and Ayutoye Kingdom of Dai nationality, and Ahong Kingdom began the process of localization.

From the middle of16th century to the middle of18th century, the Dai people in the north were completely controlled by the Han and Ming dynasties, and then by the Manchu dynasty. The great city kingdom in the south rose again from the kingdom of Xu Dong in Myanmar, and Lanna and Lancang became vassals of the great city kingdom.

In the middle and late period of18th century, the kingdom of Bombay invaded the kingdom of Ayutthaya, occupied Lanna and Lancang, and the southern Dai people were enslaved by the Burmese. 1767, general Peter Zheng Xin drove away the Burmese army and established the "annexed kingdom of Wu Li" in Wu Li. Lanna and Lancang also took the opportunity to leave Myanmar for independence. 1782, Pierre Chakri overthrew Wu Li's political power, established the "Kingdom of Siam" in Bangkok, and unified the Nandai regime of Wu Li, Lanna and Lancang.

/kloc-in the 0 ~ (th) century, the Ahong Kingdom of the Dai nationality was weakened by religious conflicts. 1822, the Burmese took the opportunity to send troops to capture the kingdom of Ahong. Two years later, the British drove away the Burmese and made Ahong Kingdom their colony. 1885, after Britain conquered the Burmese, it occupied the Dai area in northern Myanmar. 1893, the French occupied Lancang, the vassal state of Siam (at this time it was divided into Luang Prabang, Vientiane and champasak).

In the 20th century, after the outbreak of World War II, Siam, which attempted to unify the Dai areas, allied itself with Japan and sent troops to occupy the Dai areas in northern Myanmar. The former king of Luang Prabang in Lancang once declared the independence of the Dai people under the Federation of France, India and zhina with the help of the Japanese army, and established the kingdom of Laos. After World War II, the Dai people in northern Myanmar and the Burmese people in southern Myanmar jointly formed the "Union of Myanmar", and Sao Shwe Thaik, a noble from A Dai, became the first president of the Union of Myanmar. Dai people in the Yarlung Zangbo River valley (northeast India) were ruled by India after independence; People's Republic of China (PRC) ruled the Dai people in Meng Ling and Luchuan, and established Xishuangbanna Dai Autonomous Prefecture, Dehong Autonomous Prefecture and local autonomous governments at all levels. Because of the outbreak of the cold war in the world, Laos became a place where two camps wrestled, and 1975 became a socialist country; Siam, which has been renamed "Kingdom of Thailand", has become the most important ally of the United States, and the constitutional monarchy has been consolidated and developed.
