吴姓士族与刘宋建国

东晋末年，由于一系列历史条件的相互作用，使得出身寒微的刘裕和仕途坎坷的吴姓士族结成了同盟关系。吴姓士族对刘裕忠心耿耿，追随刘裕南征北战，参与了刘宋建国前几乎所有重大军事政治行动，为刘宋建国立下了汗马功劳，也得到了刘裕的器重和信任。刘宋建国后，虽然吴姓士族的地位有所提高，但刘宋皇室为取得侨姓高门的认同，大力笼络侨姓高门，吴姓士族的地位依然低下。

The Wu-Family and the Founding of the Liu-Song Dynasty

At the end of the Eastern Jin Dynasty,due to the interaction of a series of historical factors,Liu Yu, who had a poor family background,made alliance with the WuFamily who were not successful in the official career.The WuFamily were loyal to Liu.They campaigned with him all across the country,and had taken part in all important military and political events,which took place before the founding of the Liu Song Dynasty.Therefore,the Wufamily had contributed great service to the LiuSong Dynasty,and were regarded highly and trusted by Liu Yu. After the founding of the LiuSong Dynasty,the status of the Wu-Family was elevated.Yet,it was rather low.Because,the royal family of LiuSong,in order to get the identification of the noble Qiao Family,stressed great importance to win the support of the family.
