Montesquieu

If the natu­ral pro­perty of small sta­tes is to be gover­ned as repu­blics, that of medium sta­tes is to be sub­ject to a monarch, and that of large empi­res to be domi­na­ted by a des­pot, it fol­lows that, to pre­serve the prin­ci­ples of the esta­bli­shed govern­ment, the state must be main­tai­ned at the size it already had, and that such a state will change in spi­rit to the degree that its bor­ders are contrac­ted or exten­ded.
