From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
A democratic opposition indeed could not fail with such a government to emerge; but at the time of the first Punic war it was still quite powerless. At a later period, partly under the influence of the defeats which were sustained, its political influence appears on the increase, and that far more rapidly than the influence of the similar party at the same period in Rome; the popular assemblies began to give the ultimate decision in political questions, and broke down the omnipotence of the Carthaginian oligarchy.
After the termination of the Hannibalic war it was even enacted, on the proposal of Hannibal, that no member of the council of a Hundred could hold office for two consecutive years; and thereby a complete democracy was introduced, which certainly was under existing circumstances the only means of saving Carthage, if there was still time to do so. This opposition was swayed by a strong patriotic and reforming enthusiasm; but the fact cannot withal be overlooked, that it rested on a corrupt and rotten basis.
The body of citizens in Carthage, which is compared by well-informed Greeks to the people of Alexandria, was so disorderly that to that extent it had well deserved to be powerless; and it might well be asked, what good could arise from revolutions, where, as in Carthage, the boys helped to make them.
