The treaties signed in 1648 concluded nearly a century of religious warfare by enshrining the principle of cuius regio,&nbsp;eius religio (“whose realm, his religion”). The Congress of Vienna reinstated the principle of the balance of power, based on the belief that all parties shared a common interest transcending their respective ambitions, and re-established the Concert of Nations, which for two generations stopped territorial and ideological revisionism of the type seen from 1789 to 1815.
1648年签订的条约通过信奉“谁的王国，他的宗教”（cuius regio,eius religio）原则结束了近一百年的宗教战争。维也纳会议恢复了实力平衡原则，其观念基础是所有各方拥有超越各自野心的共同利益，并重新建立了国联（Concert of Nations）。国联在两代人的时间里阻止了1789—1815年间领土和思想修正主义。相反，《凡尔赛和约》显得太严厉而无法遵循，同时又太软弱而无法强制执行，反而为二战铺平了道路。
