The An Lushan Rebellion took place in China during the Tang Dynasty, from December 16, 755 to February 17, 763. An Lushan, an ex-Tang general, declared himself emperor, establishing the rival Yan Dynasty in Northern China. The rebellion spanned the reign of three Tang emperors before it was quashed. During that time, the registered population declined by up to 36 million, though most of this was due to the breakdown of the census system during the war.
