It functioned as a legislative assembly, through which the plebeians (commoners) could pass laws, elect magistrates, and try judicial cases . The Plebeian Council was originally organized on the basis of the Curia . Thus, it was originally a "Plebeian Curiate Assembly". The Plebeian Council usually met in the well of the comitium and could only be convoked by the Tribune of the Plebs . The assembly elected the Tribunes of the Plebs and the plebeian aediles, and only the plebeians were allowed to vote . </P> <P> When the Roman Republic was founded in 509 BC, the Roman people were divided into a total of thirty curiae . The curiae were organized on the basis of the family, and thus the ethnic structure of early Rome . Each curia even had its own festivals, gods, and religious rites . The thirty curiae gathered into a legislative assembly known as the Comitia Curiata or Curiate Assembly . This assembly was created shortly after the legendary founding of the city in 753 BC, and it formally elected new Roman kings . During this time, plebeians had no political rights . Each plebeian family was dependent on a particular patrician family . Thus, each plebeian family belonged to the same curia as did its patrician patron . While the plebeians each belonged to a particular curia, only patricians could actually vote in the Curiate Assembly . </P>
