Shortly after 300 AD, barbarian invaders from Inner Asia toppled China's Western Jin dynasty, leaving the country divided and at war for several centuries. Despite this, the empire gradually formed a unified imperial order. Medieval Chinese Warfare, 300-900 explores the military strategies, institutions and wars that reconstructed the Chinese empire that has survived into modern times.

Drawing on classical Chinese sources and the best modern scholarship from China and Japan, David A. Graff connects military affairs with political and social developments to show how China's history was shaped by war.
