Nanyue's first period of antagonism with the Han dynasty lasted from 183 BC to 179 BC, when trade was suspended and Zhao Tuo severed relations with the Han. During this period, Zhao Tuo openly referred to himself as Emperor and launched an attack against the Changsha Kingdom, a feudal state of the Han dynasty, and Han troops were sent to engage Nanyue. Nanyue's armies successfully halted the southern progress of the advance, winning the respect and then allegiance of the neighboring kingdoms of Minyue and Yelang.
