itorial and the other according to
property.

_a._ It must be recollected that the only existing political
organization was that of the Patricians into 3 tribes, 30 curiae, and 300
gentes; but Servius now divided the whole Roman territory into _Thirty
Tribes_, and, as this division was simply local, these tribes contained
Plebeians as well as Patricians. But, though the institution of the
Thirty Tribes gave the Plebeians a political organization, it conferred
upon them no political power, nor any right to take part in the
elections, or in the management of public affairs. At a later time the
tribes assembled in the forum for the transaction of business, and were
hence called _Comitia Tributa_. The Patricians were then excluded from
this assembly, which was summoned by the Tribunes of the Plebs, and was
entirely Plebeian.

_b._ The means by which Servius gave the Plebeians a share in the
government was by establishing a new Popular Assembly, in which
Patricians and Plebeians alike voted. It was so arranged that the
wealthiest persons, whether Patricians or Plebeians, possessed the chief
power. In order to ascertain the property of each citizen, Servius
instituted the _Census_, which was a register of Roman citizens and
their property. All Roman citizens possessing property to the amount of
12,500 asses and upward[7] were divided into five great _Classes_. The
First Class contained the richest citizens, the Second Class the next in
point of wealth, and so on. The whole arrangement was of a military
character. Each of the five Classes was divided into a certain number of
Centuries or Companies, half of which consisted of Seniores from the age
of 46 to 60, and half of Juniores from the age of 17 to 45. All the
Classes had to provide their own arms and armor, but the expense of the
equipment was in proportion to the wealth of each Class. The Five
_Classes_ formed the infantry. To these five Classes were added two
centuries of smiths and carpenters, and two of trumpeters and
horn-blowers. These four centuries voted with the Classes. Those persons
whose property did not amount to 12,500 asses were not included in the
Classes, and formed a single century.

At the head of the Classes were the Equites or cavalry. These consisted
of eighteen centuries, six being the old patrician Equites, as founded
by Romulus and augmented by Tarquinius Priscus, and the other twelve
being chosen from the chief plebeian families.[8]
