This book uses as an index of princely power a thorough examination of the major elements of the Florentine system of criminal justice—court of the Otto Di Guardia e Balia (Eight on Public Safety), police, prisons, relations with lesser courts in the dominion—which reveals the extent of their effectiveness in the capital city and the subject territory. The author's analysis reveals the determinative role played by the fiscal limits placed on the system. These limits are more important to understanding the character of the system than is any ideology of repression or absolutism. In fact, the system of criminal justice was one of negotiation, in which various players, all with some power, deployed strategies that helped them to realize their interests. Thus, the system was flexible and relatively moderate. By this index, the terms "absolutist" and "absolutism" are not helpful in understanding the type of power exercised by the Medici Grand Dukes.
