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 new
statutes, 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.
