General tag used to refer to all of Chinese history prior to the establishment of the Republic of China in 1912, assuming given periods or events do not have their own prominent tags (ala the Romance of the Three Kingdoms period, 184-280). May be used with Chinese mythology when referring to the Three Sovereigns and Five Emperors.
Generally speaking, Classical Chinese historiography divides Imperial Chinese history into alternating periods of warring states and times when most or all of the China proper (as defined as the 18 provinces of majority Han Chinese population) were controlled by a single dynasty.
