George Willis Botsford presents a detailed monographic treatment of the popular assemblies of ancient Rome, challenging established theories of nineteenth-century scholarship. The volume begins by examining the primitive composition of the populus, the original political divisions, the thirty-five tribes, the centuriate system, and the science of auspices. The author demonstrates that the plebeians and clients were recognized citizens within the early populus and participated fully in the comitia curiata from the earliest times, opposing the conventional view of an exclusively patrician primitive state.
The central problem addressed is the true constitutional nature and historical development of the Roman voting assemblies. Botsford analyzes the distinctions between the comitia and the concilium, demonstrating that these terms did not originally divide the whole people from a mere part of the populace. Through careful induction from republican literature, he establishes that the varied assemblies fulfilled distinct legislative, judicial, and electoral functions, while remaining subject to elaborate religious checks such as auspices and obnuntiations.
The work traces the military origins of the centuries and classes under Servius Tullius and subsequent reforms down to the Punic wars. The author explains how military organization directly influenced political voting units, and how census ratings and property qualifications determined the citizen's role in the state. He covers the historical growth of the equestrian centuries, the shifting burden of taxation and military service, and the gradual equalization of social ranks between patricians and plebeians.
Special attention is given to the calata comitia and the procedural mechanics of the curiate assembly, including testaments, adoptions, and the lex curiata de imperio. Botsford argues that the requirement of the curiate law originated as an early form of popular consent to royal and consular power, persisting into the late Republic long after the assembly itself had dwindled into a formal gathering represented by thirty lictors.
Throughout the study, the author maintains a conservative historical method, building generalizations upon verifiable facts rather than abstract hypotheses. By comparing Roman institutions with those of other ancient Mediterranean and Indo-European peoples, the work illuminates the universal patterns of social stratification and political evolution. The volume concludes by clarifying the complex procedures of the comitial days, the role of augurs, and the frequent political manipulation of religious omens during the final century of the Republic.
