Zhao Tuo
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.
