Political power in Rome had traditionally rested with the aristocrats; now, it lay
increasingly with the families of the new commercial class. (a) Individuals
captured office not so much on the strength of their political philosophy and
policy but on the appeal of their personalities, charisma, and conquests. (b) The
attainment of high political office became the main goal of these families
because it meant prestige, power, and more wealth. (c) Rome began to be
dominated by men who were self-seeking, larger-than-life figures who won the
support of the masses through the distribution of free food, olive oil, and wine,
and the sponsoring of public entertainment. (d) Abundance that flowed to Rome
from the fertile fields of its provinces overseas – Carthage, Sicily, Sardinia, and
Numidia – allowed free distributions to the restless and unemployed urban
proletariat.
