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]
