The Roman constitution then, as gradually developed by the necessities and crises that arose, which I have not space to mention, was a wonderful monument of human wisdom. The nobility were very powerful from their wealth and influence, but the people were not ground down. There were no oppressive laws to reduce them to practical slavery; what rights they gained they retained. They constantly extorted new privileges, until they were sufficiently powerful to be courted by demagogues. It was the demagogues, generally aristocratic ones, like Catiline and Caesar, who subverted the liberties of the people by buying votes. But for nearly five hundred years not a man arose whom the Roman people feared, and the proud symbol "SPQR," on the standards of the armies of the republic, bore the name of the Roman Senate and People to the ends of the earth. When, however, the senate came to be made up of men whom the great generals selected; when the tribunes played into the hands of the very men they were created to oppose; when the high-priest of a people, originally religious, was chosen politically and without regard to moral or religious consideration; when aristocratic nobles left their own ranks to steal the few offices which the people controlled,--then the constitution, under which the Romans had advanced to the conquest of the world, became subverted, and the empire was a consolidated despotism. Under the emperors there was no constitution, since they combined in their own persons all the great offices of state, and controlled the senate, the army, the tribunals of the law, the distant provinces, the city itself, and regulated taxes and imposed burdens as they pleased. The senate lost its independence, the courts their justice, the army its spirit, and the people their hopes. And yet the old forms remained; the senate met as in the days of the Gracchi, and there were consuls and praetors as before.
