arose out of the fights between the plebs and the populus.
The new constitution, attributed to rex Servius Tullius and following the Grecian model, more especially that of Solon, created a new public assembly including or excluding all the members of populus and plebs according to whether they rendered military service or not. The whole population, subject to enlistment, was divided into six classes according to wealth. The lowest limitis in the five highest classes were: I., 100,000 ass; II., 75,000; III., 50,000; IV., 25,000; V., 11,000; which according to Bureau de la Malle is equal to about $3,155, $2,333, $1,555, $800, and $388. The sixth class, the proletarians, consisted of those who possessed less and were exempt from military service and taxes.

To this were added 18 centuriae of horsemen composed of the most wealthy. Hence, there were 193 centuriae, giving a lowest majority vote of 97. Now the horsemen and the first class alone had together 98 votes. Being in the majority, they had only to agree, and they could pass any resolution without asking the consent of the other classes.

The curiae and the gentes composing them now were degraded to mere private and religious congregations, analogous to their Attic prototypes, and as such they vegetated on for a long time. But the assembly of curiae soon became obsolete. In order to drive also the three old tribes out
