). The term
fanzhen literally means "buffer town", and refers to the system of settling troops in strategic locations along the empire's border areas, which during the Tang Dynasty came under the control of provincial military governors, or
jiedushi. As control of these
fanzhen devolved from central authority into the hands of the local leaders, they at times became powerful enough to threaten the imperial Chinese central government during the Tang Dynasty, (618–907 CE) particularly during and after the

s who had come to dominate the life of the Imperial Court. Xianzong died in 820 CE, possibly as a result of court intrigue, and his successors were unable to stop the dynasty's decline. The ambitions of the
jiedushi, in tandem with the corruption of the Imperial Court eunuchs who dominated the central civil administration and even attained high military command under the later Tang, contributed to the eventual disintegration of the Tang monarchy. A brief resurgence under emperors Wuzong and Xuānzong failed to halt the eventual decline of the dynasty, which collapsed following a further series of revolts that included the Wang Xianzhi and Huang Chao rebellions.
Parallels are evident between the rise of the fanzhen in Tang China and the rise of feudalism in medieval Europe following the decline of the Carolingian Empire.
