Yunnan
Yunnan is an inland province in Southwestern China, spanning approximately and has a population of 47.2 million. The capital of the province is Kunming. The province borders the Chinese provinces of Guizhou, Sichuan, autonomous regions of Guangxi and Tibet, as well as Southeast Asian countries Myanmar, Vietnam, and Laos. Yunnan is China's fourth least developed province based on disposable income per capita in 2014.
Yunnan is situated in a mountainous area, with high elevations in the Northwest and low elevations in the Southeast. Most of the population lives in the eastern part of the province. In the west, the altitude can vary from the mountain peaks to river valleys as much as. Yunnan is rich in natural resources and has the largest diversity of plant life in China. Of the approximately 30,000 species of higher plants in China, Yunnan has perhaps 17,000 or more. Yunnan's reserves of aluminium, lead, zinc and tin are the largest in China, and there are also major reserves of copper and nickel. Historically, the southwestern Silk Road to Bhitargarh in Bangladesh passed through modern Yunnan.
Parts of Yunnan formed the Dian Kingdom during the 3rd and 2nd centuries BC. The Han dynasty conquered the Dian Kingdom in the late 2nd century BC, establishing the Yizhou Commandery in its place. During the chaos of the Three Kingdoms period, imperial Chinese authority in Yunnan weakened, and much of the region came under the control of the Cuanman. The area was later ruled by the Sino-Tibetan-speaking kingdom of Nanzhao from, followed by the Bai-ruled Dali Kingdom. After the Mongol conquest of the region in the 13th century, Yunnan was conquered and ruled by the Ming dynasty.
From the Yuan dynasty onward, the area was part of a central government-sponsored population movement towards the southwestern frontier, with two major waves of migrants arriving from Han-majority areas in northern and southeast China. As with other parts of China's southwest, Japanese occupation in the north during World War II forced another migration of Han people into the region. These two waves of migration contributed to Yunnan being one of the most ethnically diverse provinces of China, with ethnic minorities accounting for about 34 percent of its total population. Major ethnic groups include Yi, Bai, Hani, Zhuang, Dai, and Miao. Yunnan has also been identified as the birthplace of tea, and as the region of origin of the plant genus Cannabis.
Etymology
The name "Yunnan" first referred to a place when the Han dynasty created Yunnan County near modern Xiangyun. During the Tang dynasty, Emperor Xuanzong gave Piluoge, the chief of Nanzhao, the title of "King of Yunnan", because Nanzhao originated from Yunnan county. Gradually the king of Yunnan controlled more and more territory, and "Yunnan" became the common name of this area. Therefore, the Yuan dynasty created Yunnan Province after it occupied the Dali Kingdom.Han dynasty literature did not record the etymology of "Yunnan", and there are many theories about its origin. One common theory states that the name means "south of colorful clouds". Some annals in the Ming dynasty, for example Dian Lüe and Yunnan General Annals, support this. However, modern historian Tan Qixiang states that this theory is a superficial explanation of the literal meaning. Another common theory is that the name means "south of Yun Range" However, this has been disproven because the name "Yunling Mountains" first appeared in Tang dynasty literature, but the name "Yunnan" first appeared during the Han dynasty. Modern research gives more conjectures. You Zhong said "Yunnan" means "south of the mountain with clouds". Wu Guangfan said "Yunnan" might be a Loloish or Bai name.
History
Prehistory
The Yuanmou Man, a Homo erectus fossil unearthed by railway engineers in the 1960s, has been determined to be the oldest-known hominid fossil in China, dating back to an estimated 1.7 million years ago. By the Neolithic period, there were human settlements in the area of Lake Dian. These people used stone tools and constructed simple wooden structures.Dian Kingdom
Around the 3rd century BC, the central area of Yunnan around present day Kunming was known as Dian. The Chu general entered the region from the upper Yangtze River and set himself up as "King of Dian". He and his followers brought into Yunnan an influx of Chinese influence, the start of a long history of migration and cultural expansion.Qin and Han dynasties
In 221 BC, Qin Shi Huang unified China and extended his authority south. Commanderies and counties were established in Yunnan. An existing road in Sichuan – the "Five Foot Way" – was extended south to around present day Qujing, in eastern Yunnan. In 109 BC, the Han dynasty conquered Dian during its southern expeditions. Under orders from Emperor Wu, General was sent south to Yunnan, eventually establishing the Yizhou commandery. By this time, agricultural technology in Yunnan had improved markedly. The local people used bronze tools, plows and kept a variety of livestock, including cattle, horses, sheep, goats, pigs and dogs. Anthropologists have determined that these people were related to the people now known as the Tai. They lived in tribal congregations, sometimes led by exiled Chinese.During the Three Kingdoms, the territory of present-day Yunnan, western Guizhou and southern Sichuan was collectively called Nanzhong. The dissolution of Chinese central authority led to increased autonomy for Yunnan and more power for the local tribal structures. In AD 225, the famed statesman Zhuge Liang led three columns into Yunnan to pacify the tribes. His seven captures of Meng Huo, a local magnate, is mythologized in the Romance of the Three Kingdoms.
Cuan Kingdom
In the 4th century, northern China was largely overrun by nomadic tribes from the north. In the 320s, the Cuan clan migrated into Yunnan. Cuan Chen named himself king and held authority from Lake Dian, then known as Kunchuan. Henceforth the Cuan clan ruled eastern Yunnan for over four hundred years.International trade flowed through Yunnan. An ancient overland pre-Tang trade route from Yunnan Province passed through Irrawaddy in Burma to reach Bengal. Yunnan was inhabited by so-called barbarians not fully under the control of the Tang government and the route, though ancient, was not used much in pre-Tang times, and Chinese attempts to control the route were disrupted by the rise of Nanzhao.
Nanzhao period
Yunnan was settled by several local tribes, clans, and cultures before the 8th century. Around Lake Erhai, namely, the Dali area, there emerged six zhao: Mengzi, Yuexi, Langqiong, Dengdan, Shilling, and Mengshe. Zhao was an indigenous non-Chinese language term meaning "king" or "kingdom." Among the six regimes Mengshe was located south of the other five; therefore given the new, larger context, it was called Nanzhao.By the 730s Nanzhao had succeeded in bringing the Erhai Lake–area under its authority. In 738, the western Yunnan was united by Piluoge, the fourth king of Nanzhao, who was confirmed by the imperial court of the Tang dynasty as king of Yunnan. Ruling from Dali, the thirteen kings of Nanzhao ruled over more than two centuries and played a vital role in the dynamic relationship between the Tang dynasty and the Tibetan Empire as a buffer state.
By the 750s, Nanzhao had conquered Yunnan and became a potential rival to Tang China. The following period saw several conflicts between Tang China and Nanzhao. In 750, Nanzhao attacked and captured Yaozhou, the largest Tang settlement in Yunnan. In 751, Xianyu Zhongtong, the regional commander of Jiannan, led a Tang campaign against Nanzhao. The king of Nanzhao, Geluofeng, regarded the previous incident as a personal affair and wrote to Xianyu to seek peace. However, Xianyu Zhongtong detained the Nanzhao envoys and turned down the appeal. Confronted with Tang armies, Nanzhao immediately turned its allegiance to the Tibetan Empire. The Tubo and Nanzhao agreed to be "fraternal states"; Geluofeng was given the titles zanpuzhong. The Nanzhao-Tubo alliance ensured a disastrous defeat for Xianyu's expedition, with the Tang general's army of 80,000 men being reduced to a quarter of its original size.
Tang China did not give up after one failure. In 753, another expedition was prepared, but this was also defeated by Nanzhao. In 754, the Tang organized an army of more than 100,000 troops that advanced to the Dali plain, resulting in only another slaughter. By the end of the eighth century, Tang was no longer a major threat to Nanzhao.

Nanzhao's expansion lasted for several decades. In 829, Nanzhao suddenly plundered Sichuan and entered Chengdu. When it retreated, hundreds of Sichuan people, including skilled artisans, were taken to Yunnan. In 832, the Nanzhao army captured the capital of the Pyu kingdom in modern upper Burma. Nanzhao also attacked the Khmer peoples of Zhenla. Generally speaking, Nanzhao was then the most powerful kingdom in mainland Southeast Asia, and played an extremely active role in multistate interactions.
In 859, Nanzhao captured Bozhou, and this event exacerbated the Nanzhao-Tang clashes. When the Tang governor of Annam took Bozhou back in the following year, Nanzhao, with the help of native peoples, occupied Hanoi as the Tang army moved to Bozhou. When the Tang forces returned, Nanzhao troops retreated from Hanoi but attacked and plundered Yongzhou. In the winter of 862, Nanzhao, allying with local groups, led an army of over 50,000 men to invade Annam again. It is reported that the Tang forces lost over 150,000 soldiers in the two Annam battles. The autumn of 866 saw Tang victory in Hanoi and soon all of the Nanzhao forces were driven away. But Tang China had lost its ability to attack Nanzhao.
While Nanzhao was being defeated in Annam, it still occasionally attacked Sichuan. In 869, Shilong, the eighth king and the first empire of Nanzhao, invaded Sichuan. In 874, Nanzhao attacked Sichuan again.
In 902, Zheng Maisi, the Qingpingguan of Nanzhao, murdered the infant king of Nanzhao, and established a new kingdom called Dachanghe. Nanzhao, a once-powerful empire, disappeared. In 928, Yang Ganzhen usurped the Dachanghe king and established Zhao Shanzheng, a qingpingguan as emperor of Datianxing. In 929, Yang Qianzhen abolished Zhao Shanzheng and established himself as Emperor of Dayining.
