In his application of statistical methods to history, Mr. Molho offers a new approach to the study of Florentine politics.

Scholars have long recognized that Florence’s deficit-financing of its wars of independence against the Visconti of Milan had far-reaching economic, political, and social effects, but this is the first document-based history to provide concrete support for that general knowledge.

Focusing on the governmental and fiscal agencies of Florence as well as a number of memoirs and account hooks written by Florentine citizens, Mr. Molho has gathered and statistically reconstructed much archival material on Florentine taxation, public income, and expenses.

He concludes that between 1423 and 1433 Florence underwent a prolonged and vast fiscal crisis that affected both the fiscal structure of the city and its constitutional and institutional framework. His work thus sheds new light on Cosimo de’ Medici’s rise to power in 1434.

How did propertied families in late medieval and early modern Florence maintain their power and affluence while equally important clans elsewhere were fatally undermined by the growth of commerce and personal freedom, and the consequences of the Plague? Drawing on a vast array of archival research—from letters and memoirs to fiscal declarations to records of the Dowry Fund, Anthony Molho suggests that the answer is found in the twin institutions of arranged marriage and the dowry.

Molho focuses on the relations between Florentine families of this period and demonstrates that the links among families—created by arranged marriages within a narrow and well-defined social class, a system of dowries that was a combination of speculation and manipulation, and an entrenched memory of these processes—account for the resilience of this ruling class. The individuals or single families whose records Molho has scrutinized, as well as his analysis of several thousand marriages over nearly a century and a half, illuminate a culture that consistently and relentlessly subordinated individual goals and preferences to larger and deeper concerns. The book combines the application of quantitative methods and close reading of contemporary texts in order to gain new insights into the history of Florence in the late Middle Ages.
