In recent decades, the Tang dynasty (618-907) has acquired a reputation
as the most 'cosmopolitan' period in Chinese history. The standard
narrative also claims that this cosmopolitan openness faded after the An
Lushan Rebellion of 755-763, to be replaced by xenophobic hostility
toward all things foreign. This Element reassesses the
cosmopolitanism-to-xenophobia narrative and presents a more
empirically-grounded and nuanced interpretation of the Tang empire's
foreign relations after 755.
