| The patriarchal clan system in Spring and Autumn period presented a unique morphology and characteristics. On one hand there had been a lot of cases that the patriarch system was forsaken and damaged. Seen from this perspective, it wavered to some degree. On the other hand, the patriarchal clan system conception was universal and the clan still made an important role in social and political life at that time. Moreover, the relationship between Zongtong and Juntong was ambiguous, and the status and powers of monarch wasn’t on the same level compared with future generations. In addition, the ceremony disintegration, from the perspective of nobility transgression, could not summarize all the characteristics of the etiquette. In fact, the social elites understood the effect of etiquette very well. They even paid great attention to and made use of it to protect their own lives.For the widespread regicides during the Spring and Autumn period, there had been the "Regicide thirty-six" argument. Whether the number was regarded precise or not, the criteria was relatively stringent, which was obviously adverse for us to cognize the plentiful regicides. There were actually 79 incidents if we did some new statistical analysis. Based on the primary motivation that the various incidents occurred, they can be classified into six kinds:royal clan vying for throne, similar to royal clan vying for throne, ministers monopolizing power, personal enmity, supporting new monarch and being killed in war.The regicides occurred in almost all major nations during the Spring and Autumn period and their social and political background was different from each other. Royal clan vying for throne and ministers monopolizing power were the only two types in Jin while the personal enmity and bureaucrats grabbing power were prominent in Qi although there were the same most incidents in these two countries. More specifically, the different surname bureaucrats were powerful in both Jin and Qi, but Quwo usurping Yi’s throne caused some monarchs losing their lives in former state and the clan of Chen replacing the royal clan did the same in the latter. In addition, royal clan vying for throne was the only type in Chu, which was closely related to its regime’s never moving down. As for Lu, several monarchs had become victims of the three-Huan controlling the country. Moreover, the regicides were various in Song, Zheng and Wei, reflecting some aspects of political formation on that era.The regicides seriously damaged political ethics. However, the proportion ofKingslayers being suppressed was low, which was mainly determined by the practical political factors. Except for some fatuous monarchs, it’s still deeply taboo to regicide at that time. In addition, certain regicides had something to do with powers interference, and it often resulted in a substitution between the orthodox regime and unorthodox one. However, they tended to support the emperor when there was a civil strife in Zhou. The sharp contrast was also closely related to the reality of political environment. Avoid being killed by other royal clans, the new monarch usurping throne usually expulsed royal clans and appointed different surname talents. These measures had a great influence on the social and political change and even the development process of the Spring and Autumn period. |
