There is no other published book in English studying the constitution of the Roman Republic as a whole. Yet the Greek historian Polybius believed that the constitution was a fundamental cause of the exponential growth of Rome's empire. Knowledge of Rome's political institutions is essential both for ancient historians and for those who study the contribution of Rome to the republican tradition of political thought from the Middle Ages to the revolutions inspired by the Enlightenment.
Extremely well-researched book. Focusing mostly on debates over the form of certain institutions, it delves too much for my taste into legal minutiae important more to the scholar than the general reader. Despite this, presentation of the contrasting interpretations of the different institutions - especially with comparison to the lights of Polybius - were interesting and valuable to me. Please note that I put this book down after completion of the chapter on the Senate, for the reasons stated above.
