It would be outside our present purpose to follow the learned scholars who have sought to deduce ingenious and complicated theories from some doubtful phrase in an old codex, or the vague words of some chronicler. It is certain that the Roman Empire was an aggregation of municipalities exercising self-government. The city was the primitive atom, the germ-cell, as it may be called, of the great Roman society that began to disperse when the capital lost the power of attraction required to bind together so great a number of cities separated by vast tracts of country either totally deserted, or only inhabited by the slaves cultivating the soil. The barbarians, on the other hand, knew nothing of citizen life, and the _Gau_ or _Comitatus_ (whence the term _contado_ is derived), only comprising embryo towns, or rather villages, which were sometimes burnt when the tribes moved on elsewhere, resembled the primitive nucleus of Teutonic society. In the _comitatus_ the count ruled and administered justice with his magistrates; the chiefs of the soldiery were his subordinates, and became barons later on. Several countships joined together formed the dukedoms or marquisates into which Italy was then divided, and the whole of the invading nation was commanded by a king elected by the people. When, therefore, the Germanic tribes held sway over the Latin, the _Gau_ held sway over the cities which indeed formed its constituents. And the counts, as military chieftains, ruled the conquered land, of which the victors appropriated one-third. The Goths pursued the same plan; so too the Greeks, who replaced all counts by their own _duces_; and so also the Longobards. Only the latter's rule was far more tyrannous, especially at first, and their history is very obscure. They began by slaughtering the richest and most powerful Romans; they seized one-third of the revenues, it would seem, instead of the lands, thus leaving the oppressed masses without any free property, and consequently in a worse condition than before. The Goths had permitted the Romans to live in their own way, but the Longobards respected no laws, rights, nor institutions of the vanquished race. On this head Manzoni remarks[9] that no mention is found of any Italian personage, whether actual or imaginary, in connection with any royal office or public act of the time. Nevertheless, from absolute tyranny, and even downright subjection, to the total destroyal of every Roman law, right, and institution, there is a long step. In order to attribute to the Longobards--numbering, it is said, some 130,000 souls in all--the total extinction of Roman life in every direction, we must credit them with an administrative power, far too well ordered and disciplined, too steadfast and permanent, to be any way compatible with their condition. How could a tribe incapable of comprehending Roman life persecute it to extinction on all sides? Granting even, although this is another
