Niccolò Machiavelli

“ To suffer the overthrow of such an extensive empire, established by the blood of so many brave and virtuous men, showed no less folly in the princes themselves than infidelity in their ministers; for not one irruption alone, but many, contributed to its ruin ”

“ Attila having left Italy, Valentinian, emperor of the west, thought of restoring the country; and, that he might be more ready to defend it against the barbarians, abandoned Rome, and removed the seat of government to Ravenna. The misfortunes which befell the western empire caused the emperor, who resided at Constantinople, on many occasions to give up the possession of it to others, as a charge full of danger and expense; and sometimes, without his permission, the Romans, seeing themselves so abandoned, created an emperor for their defense, or suffered some one to usurp the dominion. ”

“ Irruption of Northern people upon the Roman territories—Visigoths—Barbarians called in by Stilicho—Vandals in Africa—Franks and Burgundians give their names to France and Burgundy—The Huns—Angles give the name to England—Attila, king of the Huns, in Italy—Genseric takes Rome—The Lombards.
The people who inhabit the northern parts beyond the Rhine and the Danube, living in a healthy and prolific region, frequently increase to such vast multitudes that part of them are compelled to abandon their native soil, and seek a habitation in other countries. ”
