Palatine, Aventine, Capitoline, Coelian, Quirinal, Viminal, and
Esquilian,--for, though new suburbs grew up beyond this wall, the legal

The inhabitants within the walls were divided into four "regions" or
districts--the Palatine, the Colline, the Esquiline, and the Suburran.
The subjected districts outside, which were inhabited by plebeians,
were divided into twenty-six other regions, thus forming thirty tribes
containing both plebeians and patricians. The census gave Servius a

information he separated the entire population into six classes,
comprising one hundred and ninety-three subdivisions or "centuries,"
thus introducing a new principle, and placing wealth at the bottom of
social distinctions, instead of birth. This naturally pleased the
plebeians, but was not approved by the citizens of high pedigree, who
thus lost some of their prestige. The newly formed centuries together
constituted the _Comitia Centuriata_ (gathering of the centuries),
or National Assembly, which met for business on the Campus Martius,
somewhat after the manner of a New England "Town Meeting." In these
conclaves they elected certain magistrates, gave sanction to
legislative acts, and decided upon war or peace. This Comitia formed
