High Quality Content by WIKIPEDIA articles! The Curiate Assembly (comitia curiata) was the principal assembly during the first two decades of the Roman Republic. During these first decades, the People of Rome were organized into thirty units called "Curia". The Curia were ethnic in nature, and thus were organized on the basis of the early Roman family, or, more specifically, on the basis of the thirty original Patrician (aristocratic) clans. The Curia formed an assembly for legislative, electoral, and judicial purposes. The Curiate Assembly passed laws, elected Consuls (the only elected magistrates at the time), and tried judicial cases. Consuls always presided over the assembly. While Plebeians (commoners) could participate in this assembly, only the Patricians (the Roman aristocrats) could vote.
