京口集团与刘宋政治

The Jing Kou Group and Politics of the Liu Song Dynasty

东晋后期，京口集团中衰，刘裕以京口、晋陵地区的流民为基础，重振京口集团，并以其为主要的军事力量，内征外讨，完成了覆晋建宋的大业。京口集团亦成为刘家政权支撑性的政治、军事力量。刘家前期，京口集团的势力由中央扩散到重要的藩镇，参与重大的政治事件，其力量的兴衰极大地影响了当时的政治格局。随着京口重镇地位的丧失、流民来源的枯竭、京口主将的死亡、其他方镇的兴起，京口集团逐渐衰落。刘家后期，已很难寻觅京口集团的踪迹。

In the late period of the Eastern Jin Dynasty,the Jin Kou group declined half way. Liuyu,taking the refugees of the regions of Jin Ling as his ruling base,restored the power of Jing Kou group,and then with them as his main military pow- er went on a punitive expedition both domestically and externally,fulfiling the great mission of over whelming the Jin Dynasty and establishing the regime of Liu Song. The Jing kou group turn powerful powerful political and military military of the Liu Song Dy- nasty In the former period of Liu Song,the Jing Kou extended its power from the central region to some important vassal town,actively participating in the important political incidents. As a result,the rise and fall of its power caused a great in flu- ence on the then political pattern.With the decline of the key position of Jing Kou,the lack of the sources of the refugees,the death of the chief commanders and the rise of other local towns,the Jing Kou group gradually declined In the late period,it was very difficult to track down the trace of the Jing Kou group.
