趙佗
Peace meant that Nanyue lost its imperial authority over the other Yue states. Its earlier empire had not been based on supremacy, but was instead a framework for a wartime military alliance opposed to the Han. The army Zhao Tuo had created to oppose the Han was now available to deploy against the Âu Lạc kingdom in modern-day northern Vietnam. This kingdom was conquered in 179–180 BC. Zhao Tuo divided his kingdom into two regions: Cửu Chân and Giao Chỉ. Giao Chỉ now encompasses most of northern Vietnam. He allowed each region to have representatives to the central government, thus his administration was quite relaxed and had a feeling of being decentralized. However, he remained in control. By the time Zhao Tuo died in 136 BC, he had ruled for more than 70 years and outlived his sons.
