军权,历来是政权的核心,掌握军权是控制政权的关键。终晋之世,琅琊王氏未改变其在东晋政坛的门阀地位,但其显然经历了一个由琅琊王氏一门独大到先后为庾、桓、谢、太原王氏分享门阀政治特权的过程,即由“王与马,共天下”转变为与其他门阀与皇权共治天下,这种政治格局的转变与琅琊王氏对军权掌控力的强弱有密切关系。 The military power, which has always been the core of the government, is the key to controlling the government. After the end of Jin Dynasty, Langya Wang did not change its status as a gatekeeper in the Eastern Jin Dynasty. However, it apparently underwent a process of sharing the political privilege of the gatekeeper from Langya Wang to the succession , That is, from “the king and the horse, the world” into the world with other gatekeepers and the imperial power. The change of this political pattern is closely related to the strength of Wang Lang’s control of the military power.
