The established work, which can be used both as a comprehensive presentation and as a reference, is now available at an affordable price in the Universal Library. The volume offers the most important information on the organization of the Roman state in a historically meaningful two-part division (Republic and Imperial period): social structures and class systems, magistracies and political bodies, taxation and legal systems, provincial administration and military, aspects of the imperial office. Numerous source texts, a detailed list of Roman consuls and dictators, as well as a bibliography complement the presentation.
