Soon even the plebeians were admitted to the right of voting also in the curies, and by that step the old burgess-body lost the right of meeting and of resolving at all.
The curial organization was virtually rooted out, in so far as it was based on the clan-organization and this latter was to be found in its purity exclusively among the old burgesses.

When the plebeians were admitted into the curies, they were certainly also allowed to constitute themselves -de jure- as--what in the earlier period they could only have been -de facto-( 10)--families and clans; but it is distinctly recorded by tradition and in itself also very conceivable, that only a portion of the plebeians proceeded so far as to constitute -gentes-, and thus the new curiate assembly, in opposition to its original character, included numerous members who belonged to no clan.
All the political prerogatives of the public assembly--as well the decision on appeals in criminal causes, which indeed were essentially political processes, as the nomination of magistrates and the adoption or rejection of laws--were transferred to, or were now acquired by, the assembled levy of those bound to military service; so that the centuries now received the rights, as they had previously borne the burdens, of citizens.

In this way the small initial movements made by the Servian constitution--such as, in particular, the handing over to the army the right of assenting to the declaration of an aggressive war( 11)--attained such a development that the curies were completely and for ever cast into the shade by the assembly of the centuries, and people became accustomed to regard the latter as the sovereign people.
In this assembly debate took place merely when the presiding magistrate chose himself to speak or bade others do so; of course in cases of appeal both parties had to be heard.

A simple majority of the centuries was decisive.
As in the curiate assembly those who were entitled to vote at all were on a footing of entire equality, and therefore after the admission of all the plebeians into the curies the result would have been a complete democracy, it may be easily conceived that the decision of political questions continued to be withheld from the curies; the centuriate assembly placed the preponderating influence, not in the hands of the nobles certainly, but in those of the possessors of property, and the important privilege of priority in voting, which often practically decided the election, placed it in the hands of the -equites- or, in other words, of the rich.
Senate The senate was not affected by the reform of the constitution in the same way as the community.

The previously existing college of elders not only continued exclusively patrician, but retained also its essential prerogatives--the right of appointing the interrex, and of confirming or rejecting the resolutions adopted by the community as constitutional or unconstitutional.
