↑ “ Servius Tullius created his classes, guided by an aristocratic principle. Titus of Libya and Dionysius of Halicarnassus tell us how he concentrated the right to vote in the hands of the first citizens of the state. He divided the Roman people into one hundred and ninety-three centuries, forming six classes. Having placed the wealthy in a relatively smaller number in the first centuries, and the less wealthy in a comparatively larger number in the next centuries, he threw the whole mass of poor people into one last century. And since the centuries had only one vote each, it turned out that the right to vote belonged not so much to individuals as to influence and wealth. "// Montesquieu " On the spirit of laws "
