公元前21世纪,禹的儿子启以暴力形式夺取伯益的部落联盟首领职位,建立起一整套奴隶制国家机器,夏朝成立。我国从此进入了阶级社会。奴隶制国家一旦建立,首先是设置国家机构,组织人员为国家服务,以实现奴隶主阶级的统治。脱离生产,以公职活动为特征的职业官吏群应运而生。 In the 21st century BC, Yu’s son Kai-shek took the form of violence to capture the head of the Burkina tribal alliance and established a whole series of slavery machineries. The Xia Dynasty was founded. Since then, our country has entered a class society. Once slavery countries are established, the first is to set up state agencies and organize personnel to serve the country so as to bring about the rule of slave owners. From the production, occupational official activities characterized by occupational officials came into being.
