Nanyue (), was an ancient kingdom ruled by Chinese monarchs of the Zhao family that covered the modern Chinese subdivisions of Guangdong, Guangxi, Hainan, Hong Kong, Macau, southern Fujian and central to northern Vietnam. Nanyue was established by Zhao Tuo, then Commander of Nanhai of the Qin Empire, in 204 BC after the collapse of the Qin dynasty. At first, it consisted of the commanderies Nanhai, Guilin, and Xiang.

In 196 BC, Zhao Tuo paid obeisance to the Emperor Gaozu of Han, and Nanyue was referred to by the Han dynasty as a "foreign servant", i.e. a vassal state. Around 183 BC, relations between the Nanyue and the Han dynasty soured, and Zhao Tuo began to refer to himself as an emperor, suggesting an equal status between Nanyue and the Han dynasty. In 179 BC, relations between the Han and Nanyue improved, and Zhao Tuo once again made submission, this time to Emperor Wen of Han as a subject state. The submission was somewhat superficial, as Nanyue retained autonomy from the Han, and Zhao Tuo was referred to as "Emperor" throughout Nanyue until his death. In 113 BC, fourth-generation leader Zhao Xing sought to have Nanyue formally included as part of the Han Empire. His prime minister Lü Jia objected vehemently and subsequently killed Zhao Xing, installing his elder brother Zhao Jiande on the throne and forcing a confrontation with the Han dynasty. The next year, Emperor Wu of Han sent 100,000 troops to war against Nanyue. By the year's end, the army had destroyed Nanyue and established Han rule. The dynastic state lasted 93 years and had five generations of monarchs.

The existence of Nanyue allowed the Lingnan region to avoid the chaos and hardship surrounding the collapse of the Qin dynasty experienced by the northern, predominantly Han Chinese regions. The kingdom was founded by leaders originally from the Central Plain of China and were all of Han Chinese in origin. They were responsible for bringing Chinese-style bureaucracy and handicraft techniques to inhabitants of southern regions, as well as knowledge of the Chinese language and writing system. Nanyue rulers promoted a policy of "Harmonizing and Gathering the Hundred Yue tribes" (), and encouraged ethnic Han to immigrate from the Yellow River region to the south. Nanyue rulers were then not against the assimilation of Yue and Han cultures.

In Vietnam, the rulers of Nanyue are referred to as the Triệu dynasty. The name "Vietnam" (''Việt Nam'') is derived and reversed from ''Nam Việt'', the Vietnamese pronunciation of Nanyue.

History

A detailed history of Nanyue was written in ''Records of the Grand Historian'' by Han dynasty historian Sima Qian. It is mostly contained in section (''juan'') 113, (''Ordered Annals of Nanyue''). A similar record is also found in the ''Book of Han'' Volume 95: The Southwest Peoples, Two Yues, and Chaoxian.

Founding

Qin southward expansion (218 BC)

After Qin Shi Huang conquered the six other Chinese kingdoms of Han, Zhao, Wei, Chu, Yan, and Qi, he turned his attention to the Xiongnu tribes of the north and west and the Hundred Yue peoples of what is now southern China. Around 218 BC, the First Emperor dispatched General Tu Sui with an army of 500,000 Qin soldiers to divide into five companies and attack the Hundred Yue tribes of the Lingnan region. The first company gathered at Yuhan (Modern Yugan County in Jiangxi Province) and attacked the Minyue, defeating them and establishing the Minzhong Commandery. The second company fortified at Nanye (in modern Jiangxi Province's Nankang County), and was designed to put defensive pressure on the southern clans. The third company occupied Panyu. The fourth company garrisoned near the Jiuyi Mountains, and the fifth company garrisoned outside Tancheng (in the southwest part of modern Hunan Province's Jingzhou Miao and Dong Autonomous County). The First Emperor assigned official Shi Lu to oversee supply logistics. Shi first led a regiment of soldiers through the Ling Channel (which connected the Xiang River and the Li River), then navigated through the Yangtze River and Pearl River water systems ensure the safety of the Qin supply routes. The Qin attack of the Western Valley () Yue tribe went smoothly, and Western Valley chieftain Yi-Xu-Song was killed. However, the Western Valley Yue were unwilling to submit to the Qin and fled into the jungle where they selected a new leader to continue resisting the Chinese armies. Later, a night-time counterattack by the Western Valley Yue devastated the Qin troops, and General Tu Sui was killed in the fighting. The Qin suffered heavy losses, and the imperial court selected General Zhao Tuo to assume command of the Chinese army. In 214 BC, the First Emperor dispatched Ren Xiao and Zhao Tuo at the head of reinforcements to once again mount an attack. This time, the Western Valley Yue were completely defeated, and the Lingnan region was brought entirely under Chinese control. In the same year, the Qin court established the Nanhai, Guilin, and Xiang Commanderies, and Ren Xiao was made Lieutenant of Nanhai. Nanhai was further divided into Panyu, Longchuan, Boluo, and Jieyang counties (among several others), and Zhao Tuo was made magistrate of Longchuan.

The First Emperor died in 210 BC, and his son Zhao Huhai became the Second Emperor of Qin. The following year, soldiers Chen Sheng, Wu Guang, and others seized the opportunity to revolt against the Qin government. Insurrections spread throughout much of China (including those led by Xiang Yu and Liu Bang, who would later face off over the founding of the next dynasty) and the entire Yellow River region devolved into chaos. Soon after the first insurrections, Nanhai Lieutenant Ren Xiao became gravely ill and summoned Zhao Tuo to hear his dying instructions. Ren described the natural advantages of the southern region and described how a kingdom could be founded with the many Chinese settlers in the area to combat the warring groups in the Chinese north. He drafted a decree instating Zhao Tuo as the new Lieutenant of Nanhai, and died soon afterward.

After Ren's death, Zhao Tuo, sent orders to his troops in Hengpu Pass (north of modern Nanxiong, Guangdong Province), Yangshan Pass (northern Yangshan County), Huang Stream Pass (modern Yingde region, where the Lian River enters the North River), and other garrisons to fortify themselves against any northern troops. He also executed Qin officials still stationed in Nanhai and replaced them with his own trusted friends.

Conquest of Âu Lạc

The kingdom of Âu Lạc laid south of Nanyue in the early years of Nanyue's existence, with Âu Lạc located primarily in the Red River delta area, and Nanyue encompassing Nanhai, Guilin, and Xiang Commanderies. During the time when Nanyue and Âu Lạc co-existed, Âu Lạc acknowledged Nanyue's suzerainty, especially because of their mutual anti-Han sentiment. Zhao Tuo built up and reinforced his army, fearing an attack by the Han. However, when relations between the Han and Nanyue improved, in 179 BC Zhao Tuo marched southward and successfully annexed Âu Lạc.

Proclamation (204 BC)

In 206 BC the Qin dynasty ceased to exist, and the Yue peoples of Guilin and Xiang were largely independent once more. In 204 BC, Zhao Tuo founded the Kingdom of Nanyue, with Panyu as capital, and declared himself the Martial King of Nanyue (, Vietnamese: ''Nam Việt Vũ Vương'').

Nanyue under Zhao Tuo

Liu Bang, after years of war with his rivals, established the Han dynasty and reunified Central China in 202 BC. The fighting had left many areas of China depopulated and impoverished, and feudal lords continued to rebel while the Xiongnu made frequent incursions into northern Chinese territory. The precarious state of the empire therefore forced the Han court to treat Nanyue initially with utmost circumspection. In 196 BC, Liu Bang, now Emperor Gaozu, sent Lu Jia (陸賈, not to be confused with Lü Jia 呂嘉) to Nanyue in hopes of obtaining Zhao Tuo's allegiance. After arriving, Lu met with Zhao Tuo and is said to have found him dressed in Yue clothing and being greeted after their customs, which enraged him. A long exchange ensued, wherein Lu is said to have admonished Zhao Tuo, pointing out that he was Chinese, not Yue, and should have maintained the dress and decorum of the Chinese and not have forgotten the traditions of his ancestors. Lu lauded the strength of the Han court and warned against a kingdom as small as Nanyue daring to oppose it. He further threatened to kill Zhao's kinsmen in China proper and destroying their ancestral graveyards, as well as coercing the Yue into deposing Zhao himself. Following the threat, Zhao Tuo then decided to receive Emperor Gaozu's seal and submit to Han authority. Trade relations were established at the border between Nanyue and the Han kingdom of Changsha. Although formally a Han subject state, Nanyue seems to have retained a large measure of ''de facto'' autonomy.

After the death of Liu Bang in 195 BC, the government was put in the hands of his wife, Empress Lü Zhi, who served as Empress Dowager over their son Emperor Hui of Han and then Emperor Hui's sons Liu Gong and Liu Hong. Enraged, Empress Lü sent men to Zhao Tuo's hometown of Zhending (modern Zhengding County in Hebei Province) who killed much of Zhao's extended family and desecrated the ancestral graveyard there. Zhao Tuo believed that Wu Chen, the Prince of Changsha, had made false accusations against him to get Empress Dowager Lü to block the trade between the states and to prepare to conquer the Nanyue to merge into his principality of Changsha. In revenge, he then declared himself the emperor of Nanyue and attacked the principality of Changsha and captured some neighboring towns under Han domain. Lü sent general Zhou Zao to punish Zhao Tuo. However, in the hot and humid climate of the south, an epidemic broke out quickly amongst the soldiers, and the weakened army was unable to cross the mountains, forcing them to withdraw which ended in Nanyue victory, but the military conflict did not stop until the Empress died. Zhao Tuo then annexed the neighboring state of Minyue in the east as subject kingdom. The kingdom of Yelang and Tongshi (通什) also submitted to Nanyue rule.

In 179 BC, Liu Heng ascended the throne as Emperor of the Han. He reversed many of the previous policies of Empress Lü and took a conciliatory attitude toward Zhao Tuo and the Kingdom of Nanyue. He ordered officials to revisit Zhending, garrison the town, and make offerings to Zhao Tuo's ancestors regularly. His prime minister Chen Ping suggested sending Lu Jia to Nanyue as they were familiar with each other. Lu arrived once more in Panyu and delivered a letter from the Emperor emphasizing that Empress Lü's policies were what had caused the hostility between Nanyue and the Han court and brought suffering to the border citizens. Zhao Tuo decided to submit to the Han once again, withdrawing his title of "emperor" and reverting to "king", and Nanyue became Han's subject state. However, most of the changes were superficial, and Zhao Tuo continued to be referred to as "emperor" throughout Nanyue.

Zhao Mo

In 137 BC, Zhao Tuo died, having lived over one hundred years. Because of his great age, his son, the Crown Prince Zhao Shi, had preceded him in death, and therefore Zhao Tuo's grandson Zhao Mo became king of Nanyue. In 135 BC, the king of neighboring Minyue launched an attack on the towns along the two nations' borders. Because Zhao Mo hadn't yet consolidated his rule, he was forced to implore Emperor Wu of Han to send troops to Nanyue's aid against what he called "the rebels of Minyue". The Emperor lauded Zhao Mo for his vassal loyalty and sent Wang Hui, an official governing ethnic minorities, and agricultural official Han Anguo at the head of an army with orders to separate and attack Minyue from two directions, one from Yuzhang Commandery, and the other from Kuaiji Commandery. Before they reached Minyue, however, the Minyue king was assassinated by his younger brother Yu Shan, who promptly surrendered.

The Emperor sent court emissary Yan Zhu to the Nanyue capital to give an official report of Minyue's surrender to Zhao Mo, who had Yan return his gratitude to the Emperor along with a promise that Zhao would come visit the Imperial Court in Chang'an, and even sent his son Zhao Yingqi to return with Yan to the Chinese capital. Before the king could ever leave for Chang'an himself, one of his ministers strenuously advised against going for fear that Emperor Wu would find some pretext to prevent him from returning, thus leading to the destruction of Nanyue. King Zhao Mo thereupon feigned illness and never travelled to the Han capital.

Immediately following Minyue's surrender to the Han army, Wang Hui had dispatched a man named Tang
