Whenever any people or prince withdrew their obedience from their sovereign, they immediately accorded to them the title of allies of the Roman people, and thus rendered them sacred and inviolable; so that there was no king, however great he might be, who would for a moment be sure of his subjects, or even of his family. Although the title of Roman ally was a species of servitude, it was, nevertheless, very much sought after; for the possession of this title made it certain that the recipients of it would receive injuries from the Romans only, and there was ground for the hope that this class of injuries would be rendered less grievous than they would otherwise be. Thus, there was no service which nations and kings were not ready to perform, nor any humiliation which they did not submit to, in order to obtain this distinction.... These customs were not merely some particular facts which happened at hazard. They were permanently established principles, as may be readily seen; for the maxims which the Romans acted upon against the greatest powers were precisely those which they had employed in the beginning of their career against the small cities which surrounded them.... But nothing served Rome more effectually than the respect which she inspired among all nations. She immediately reduced kings to silence, and rendered them as dumb. With the latter, it was not a mere question of the degree of their power; their very persons were attacked. To risk a war with Rome was to expose themselves to captivity, to death, and to the infamy of a triumph. Thus it was that kings, who lived in pomp and luxury, did not dare to look with steady eyes upon the Roman people, and, losing courage, they hoped, by their patience and their obsequiousness, to obtain some postponement of the calamities with which they were menaced. The "Spirit of Laws" is probably to be considered the masterpiece of Montesquieu. It is our duty, however, to say that this work is quite differently estimated by different authorities. By some, it is praised in terms of the highest admiration, as a great achievement in wide and wise political or juridical philosophy. By others, it is dismissed very lightly, as the ambitious, or, rather, pretentious, effort of a superficial man, a showy mere sciolist.
