Although the war for hegemony in the Spring and Autumn Period inevitably brought all kinds of tragedies, disasters and pains, it also produced objective effects conducive to historical progress.
supremacy wars
First, the war for hegemony accelerated the pace of reunifying China. In the wars of hegemony and annexation, big countries have opened their territories. The small country of Shandong was annexed by Qi, the small countries of Hebei and Shanxi by Jin, the small countries of Jianghuai and Hanshui by Chu, and the small country of northwest by Qin, which reduced hundreds of countries in the early Spring and Autumn Period to several big countries and realized local unification of the region. This trend of centralization has laid the foundation for the unification of the whole country and the establishment of centralization of authority.
Second, the hegemonic war has accelerated the replacement process of the old and new systems. The Spring and Autumn Period is a transitional stage in which the old and new systems alternate, and there is a struggle between the emerging feudal system and the declining slavery in society. The war of great powers for hegemony has hit and weakened the slave owners' aristocratic groups to varying degrees, cleared the obstacles on the way forward for the feudal landlord class, and promoted the development of new forces. This is especially true in the late Spring and Autumn Period.
Third, the war for hegemony has promoted national integration. During the Spring and Autumn Period, barbarians, barbarians, Rong and Di living in the surrounding areas constantly harassed the Central Plains. The overlord of the Central Plains also called for "resisting foreigners" to confront it. As a result, unprecedented ethnic migration and exchanges have emerged. Huaxia and other ethnic minorities interweave and live together, breaking the inherent geographical boundaries between ethnic groups and creating a very favorable premise for the exchange and integration of all ethnic groups, thus strengthening the economic and cultural ties between Huaxia and other ethnic groups. For example, Jiang Rong made an indelible contribution to the development of Jin after winning the "land of barbarians" given by Jin; The unique "Ronglu" (soybean) of Shanrong is also "distributed in the world" because of Qi Huangong's Shanrong. It is precisely because of the hard work, exchange of needed goods, mutual marriage and mutual influence of the people of all ethnic groups that the economic development and national integration of all ethnic groups have been effectively promoted.
In a word, the war for hegemony broke the dividing line between ethnic groups and gradually disappeared, forming several fusion centers, namely Chu in the south, Qi in the east, Jin and Yan in the north, and Thailand in the west. With the frequent contact, mutual learning and mutual promotion among ethnic groups, the social economy has achieved rapid development, and all ethnic groups have embarked on the track of feudalism.
