The Tribal Assembly (Latin: Comitia (Populi) Tributa) was an assembly consisting of all Roman citizens convened by tribes (tribus).
In the Roman Republic, citizens did not elect legislative representatives. Instead, they voted themselves on legislative matters in the popular assemblies (the Comitia Centuriata, the Comitia Tributa, and the plebeian council). Bills were proposed by magistrates and the citizens only exercised their right to vote.
