Citizens' assemblies of the Roman Republic

The legislative assemblies of the Roman Republic were political institutions in the ancient Roman Republic. According to the contemporary historian Polybius, it was the people (and thus the assemblies) who had the final say regarding the election of magistrates, the enactment of Roman laws, the carrying out of capital punishment, the declaration of war and peace, and the creation (or dissolution) of alliances. Under the Constitution of the Roman Republic, the people (and thus the assemblies) held the ultimate source of sovereignty.

Since the Romans used a form of direct democracy, citizens, and not elected representatives, voted before each assembly. As such, the citizen-electors had no power, other than to cast a vote. Each assembly was presided over by a single Roman Magistrate, and as such, it was the presiding magistrate who made all decisions on matters of procedure and legality. Ultimately, the presiding magistrate's power over the assembly was nearly absolute. The only check on that power came in the form of vetoes handed down by other magistrates.

In the Roman system of direct democracy, two primary types of gatherings were used to vote on legislative, electoral, and judicial matters. The first was the Assembly (comitia), which was a gathering that was deemed to represent the entire Roman people, even if it did not contain all of the Roman citizens or, like the comitia curiata, excluded a particular class of Roman citizens (the plebs). The second was the Council (concilium), which was a gathering of citizens of a specific class. In contrast, the Convention was an unofficial forum for communication. Conventions were simply forums where Romans met for specific unofficial purposes, such as, for example, to hear a political speech. Voters always assembled first into Conventions to hear debates and conduct other business before voting, and then into Assemblies or Councils to actually vote.
