“Wu * Jin * Liu Song * Qi * Liang * Chen
The Six Dynasties Period can be compared to Europe’s Dark Ages as it stands between the two great cultural blocks of the Han (contemporary to the Roman Empire) and the Tang (about the time the Islamic Empire emerged). The first half of this period is sometimes known as the Three Kingdoms Period and the date can vary according to eastern and western divisions between the states, but, give or take a year or two, the Wu ruled from 22-285, the Jin from 265 to 420, Liu Song from 420 to 479, the Qi from 479 to 502, Liang 502 to 557 and the Chen from 557 to 589.”
