THE RISE OF ROME 75 political rights. But before the expulsion of the kings the Commons had also acquired the right of meeting in the Assembly or Comitia called ' Centuriata.' This was constituted primarily for military purposes, and was formed in groups in such a way as to give a great preponderance of voting power to the wealthier classes. When the republic was established, the powers of the king were transferred, as we patres have already seen, to elected magistrates. The and Plebs. citizens assembled in the Comitia Centuriata were the electors, but they could only choose between candidates from Patrician families. Plebeians, however wealthy they might be, were inferior to the nobles, and marriages between the two classes were not recognised.

Outside the city there were sixteen districts and sixteen tribes. Now the Commons had grievances of two kinds : political and social. They had practically no voice in government, and they were absolutely precluded from entering the ranks of the Patricians and sharing their privileges. Hence, at The a very early stage, there took place what was Tribunate, called a Secession of the Plebeians, who threatened to withdraw from the state altogether unless concessions were made to them.
