what was the name for the powerful leaders elected by the plebeians
Plebeian Council The Concilium Plebis (English: Plebeian Council or Plebeian Assembly) was the principal assembly of the ancient Roman Republic. 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.
Representative democracy The Roman Republic was the first government in the western world to have a representative government, despite taking the form of a direct government in the Roman assemblies. The Roman model of governance inspired many political thinkers over the centuries,[7] and today's modern representative democracies imitate more the Roman than the Greek models because it was a state in which supreme power was held by the people and their elected representatives, and which had an elected or nominated leader.[8] Representative democracy is a form of democracy in which people vote for representatives who then vote on policy initiatives as opposed to a direct democracy, a form of democracy in which people vote on policy initiatives directly.[9] A European medieval tradition of selecting representatives from the various estates (classes, but not as we know them today) to advise/control monarchs led to relatively wide familiarity with representative systems inspired by Roman systems.
