Dynastic cycle (traditional Chinese: 朝代循環; simplified Chinese: 朝代循环; pinyin: Cháodài Xúnhuán) is an important political theory in the Chinese history. According to this theory, each dynasty in Chinese history, rises to a political, cultural, and economic peak and then, because of moral corruption, declines, loses the Mandate of Heaven, and falls, only to be replaced by a new dynasty. The cycle then repeats under a surface pattern of repetitive motifs.[1]
It sees a continuity in Chinese history from early times to the present by looking at the succession of empires or dynasties, implying that there is little basic development or change in social or economic structures.[2] John K. Fairbank expressed the doubts of many historians when he wrote that "the concept of the dynastic cycle... has been a major block to the understanding of the fundamental dynamics of Chinese history."[3]
The Ming dynasty, officially the Great Ming, was the ruling dynasty of China from 1368 to 1644 following the collapse of the Mongol-led Yuan dynasty. The Ming dynasty was the last imperial dynasty of China ruled by Han Chinese. The Song dynasty was an imperial dynasty of China that began in 960 and lasted until 1279. The dynasty was founded by Emperor Taizu of Song following his usurpation of the throne of the Later Zhou, ending the Five Dynasties and Ten Kingdoms period.
The fall of Ancient Rome started from about AD 190. The Roman Empire was attacked by tribes such as the Goths and the Vandals. Civil wars in parts of the empire further weakened the rule of Rome and respect for Roman law dwindled as a result.
