The sole aim of the present work is to offer a brief sketch of the history of Florence during the foundation of its liberties. So great is the importance of the theme that the historian Thiers has given long attention to it, and we know that an illustrious Italian has already made it the object of many years of strenuous research.[8] II. The history of every Italian republic may be divided into two chief periods: the origin of the commune, the development of its constitution and its liberties. In the first period, during which an old state of society is decaying and a new one arising, it is hard to distinguish the history of any one commune from that of the rest, inasmuch as it treats of Goths, Longobards, Greeks, and Franks, who dominate the greater part of Italy in turn, reducing the country, almost throughout its extent, to identical conditions. The position of conquerors and of conquered is everywhere the same, only altered by change of rulers. Amid the obscurity of the times and scarcity of information, there seems scarcely any difference between one Italian city and another. But differences are more clearly defined, and become increasingly prominent after the first arisal of freedom. Most obscure, though not of earliest date, was perhaps the origin of Florence, which tarried long before beginning to rise to importance. Our present purpose being merely to throw light on the history of the Florentine Constitution, we need not devote many words to the first period mentioned above--namely, of the origin of Italian communes in general. At one time this question was the theme of a learned, lengthy, and most lively dispute, chiefly carried on by Italian and German writers. But the scientific severity of researches, in which Italian scholars won much honour, was often impaired by patriotism and national prejudice. It being recognised that the origin of the Commune was likewise the origin of modern liberty and society, the problem was tacitly transformed into another question--_i.e._, whether Italians or Germans were the first founders of these liberties, this society? It is easy to understand how political feelings were then imported into the controversy, and effectually removed it from the ground of tranquil debate.
