Book excerpt: Friedrich Munzer's Roman Aristocratic Parties and Families is recognized by all students of Roman history as a path-breaking work in the analysis of the Roman oligarchy. Here for the first time was a description of the methods by which the few most politically important clans in Rome, originally patrician, had expanded to take in so many promising plebeians - not only from Rome but from all over Italy - and make them part of the governing class. Originally published in German in 1920, Roman Aristocratic Parties and Families is now available for the first time in English translation. This edition is also the first to contain an index and a bibliography, making it of value to scholars who are already familiar with the original work.
