During the Later Han (25–220 AD), the whole Tarim Basin again became a focus of rivalry between the Xiong-nu to the north and the Chinese to the east. In 74 AD, Chinese troops started to take control of the Tarim Basin with the conquest of Turfan. During the 1st century AD, Kucha resisted the Chinese invasion, and allied itself with the Xiong-nu and the Yuezhi against the Chinese general Ban Chao. Even the Kushan Empire of Kujula Kadphises sent an army to the Tarim Basin to support Kucha, but they retreated after minor encounters.
