Tribune of the Plebs
The Concilium Plebis (English: Plebeian Council, Plebeian Assembly, People's Assembly or Council of the Plebs) was the principal assembly of the common people of the ancient Roman Republic. It functioned as a legislative/judicial assembly, through which the plebeians (commoners) could pass legislation (called plebiscites), elect plebeian tribunes and plebeian aediles, and try judicial cases. The Plebeian Council was originally organized on the basis of the Curia but in 471 BC adopted an organizational system based on residential districts or tribes. The Plebeian Council usually met in the well of the Comitium and could only be convoked by the Tribune of the Plebs. The patricians were excluded from the Council.
