Through the last two-plus decades of nominal Tang authority the landscape was overrun by autonomous warlord armies.1 Some aspired to replacing the Tang, while others had much more limited aims, perhaps best defined as simple predation.

In the north this era is marked by the so-called Five Dynasties that began with Zhu Wen, first “emperor” of the Later Liang 後梁 “dynasty” (r. 907–912) For the next several decades, until the holistic empire was more-or-less restored by the Song in the latter half of the tenth century,
