【摘要】 东晋时期是士族集团与皇权相互依存的政治形态。到南朝时期,封建政治形态进入新的发展阶段,即以具有地域色彩的武力集团为支撑,结合仍具余威的士族集团以及地位上升的寒人势力等利益集团,在皇权主导下共同发挥作用的政治形态新阶段。论文将萧道成代宋作为切入点,以宋齐之际的政治形势发展演变为研究对象,试图对这段历史的发展逻辑窥以梗略。萧道成代宋和萧齐政权的支撑性力量是青徐集团。东晋末年刘裕攻灭南燕,青徐集团势力开始向江左政权靠拢。不过,刘宋前期,青徐势力因种种原因受到打击和压制,发展迟缓。泰始初年的皇权之争,给青徐势力提供全面介入刘宋政治的机会。随即宋明帝的误判直接导致了淮北地区的陷落,青徐集团再次丧失家园,向淮南江北进一步迁徙。青徐集团势力徙居淮南后重新聚合,很快找到萧道成作为依附合作对象,并趁机发展壮大,成为宋齐易代的主要政治军事力量。萧道成的崛起因于军功,实质而言,得益于刘宋统治集团的内部权力斗争,这为萧道成提供了政治军事发展机会。萧道成先在政争中支持明帝,转战三吴、淮北、江州,凭借优秀军事才能脱颖而出,得到镇戍淮阴的机会。他在淮阴吸纳、邀集流散于此的青徐势力,积累相当军事力量。泰始七年,萧道成进入建康中枢,随即平定刘休范与刘景素两场军事动乱,在刘宋中枢取得执政地位。同时,随着军事政治地位的增强和上升,萧道成代宋的政治野心也趁势而起。萧道成势力的坐大,引起了荆州刺史沈攸之和司徒袁粲的不安,他们先后发动政治军事行动反对萧道成,意图诛灭萧道成势力。昇明元年,萧道成利用自身政治军事优势在废立政变中执掌刘宋政治权柄,激化了与袁、沈之间的矛盾,随即展开权力斗争。萧道成在中央和国家方镇占据绝对优势和主动权,斗争以萧道成的胜利告终。萧道成代宋在一定程度上填补了长久以来高门士族与其他阶层之间的鸿沟,但这种有限的填补,并不足以改变当时社会形态。更多还原

【Abstract】 The polity in the Eastern Jin Dynasty is that the gentry group that have powerful social influence and the weak royal ruler that only have spirit charisma are interdependent on each other.With the change of historical conditions,the feudal polity entered into a new phase of development in the Southern Dynasty,a new phase of polity that various kinds of interest groups such as the gentry group passed from the Eastern Jin Dynasty that still reserved some influence in society and the interest group of the underprivileged people whose status were arose during the dynastic change period,etc,cooperated with each other under the rule of the emperor.Due to the different historical conditions as well as the different chances initiating dynastic change in the Southern Dynasty,each generation of the dynasty depended on different military groups,and formed different political development logics.Therefore,this thesis will make the replacement of the Song Dynasty by Xiao Daocheng as the breakthrough point,with the political situation development as the study object,and try to conclude the development logic of this historical periodThe supporting power of the replacement of the Song Dynasty by Xiao Daocheng and the regime of Xiao and Qi is Qing Xu interest group which arose at the end of the Eastern Jin Dynasty.After conquering the Southern Yan Dynasty,Liu Yu started to permeate his power into the Jiang Zuo regime(the regime in the south of the lower reaches of the Chang Jiang River).His power was suppressed in the early period of Liu Song regime because it was started late and had to confront many complex situations.During the period of the struggle for imperial power in the beginning of the Tai Shi era,the Qing Xu interest group entered into the Liu Song polity.However,the misjudgement of the emperor Song Ming led to the lose of the Huai Bei area directly.It lost it’s home again and had to move to another place again as well.But as one of the most powerful military groups,it’s members gathered together after the immigration to the Huai Nan area and made Xiao Daocheng who rose for his military achievements,basically benefited from the internal struggle of the Liu Song ruling group that provided great opportunities for the development of his military power and the rose of his political status,their collaborator and the rise of him.Xiao Daocheng supported the Ming emperor in the struggle for imperial power at the end of the Song Dynasty,fought in San Wu area,Huai Bei area and Jiang Zhou area,and got the chance to guard the Huai Yin area for his outstanding military abilities.He gathered the Qing Xu interest group members wandering there and accumulated his strong military power,so as to achieve the great success.In the seventh year of the Tai Shi era,he moved to Jian Kang and gradually established his position in the Liu Song regime after suppressed two political riots launched by Liu Xiufan and Liu Jiangsu separately.The strong power he developed in the court caused the disturbance of Shen Youzhi,header of the Jing Zhou area,and Yuan Can,a loyal officer to the emperor.Shen Youzhi wanted to grab power from Xiao Daocheng while Yuan Can wanted to reestablish the authority of the Liu Song royal family.At the first year of the Sheng Ming era,Xiao Daocheng took the ruling power from the fatuous emperor and established his regime with his military advantage,which sharpened the conflicts between Shen Youzhi and Yuan Can and led to their wrestles of power.Based on his abundant military and political power as well as his advantage in the Liu Song regime,Xiao Daocheng earned the initiative and eliminated all the obstacles on the way of imperial power.The replacement of the Song Dynasty by Xiao Daocheng reduced the long existed gap between the noble gentry class and other classes to some extent,but this limited change was not enough to change the abnormal social condition of that time.更多还原
