And since I have said above that nations such as those I have been describing, are often driven by wars from their ancestral homes, and forced to seek a new country elsewhere, I shall cite the instance of the Maurusians, a people who anciently dwelt in Syria, but hearing of the inroad of the Hebrews, and thinking themselves unable to resist them, chose rather to seek safety in flight than to perish with their country in a vain effort to defend it.  For which reason, removing with their families, they went to Africa, where, after driving out the native inhabitants, they took up their abode; and although they could not defend their own country, were able to possess themselves of a country belonging to others.  And Procopius, who writes the history of the war which Belisarius conducted against those Vandals who seized on Africa, relates, that on certain pillars standing in places where the Maurusians once dwelt, he had read inscriptions in these words:  “We Maurusians who fled before Joshua, the robber, the son of Nun;"[1] giving us to know the cause of their quitting Syria.  Be this as it may, nations thus driven forth by a supreme necessity, are, if they be in great number, in the highest degree dangerous, and cannot be successfully withstood except by a people who excel in arms.

When those constrained to abandon their homes are not in large numbers, they are not so dangerous as the nations of whom I have been speaking, since they cannot use the same violence, but must trust to their address to procure them a habitation; and, after procuring it, must live with their neighbours as friends and companions, as we find AEneas, Dido, the Massilians, and others like them to have lived; all of whom contrived to maintain themselves in the districts in which they settled, by securing the good will of the neighbouring nations.

Almost all the great emigrations of nations have been and continue to be from the cold and barren region of Scythia, because from the population there being excessive, and the soil ill able to support them, they are forced to quit their home, many causes operating to drive them forth and none to keep them back.  And if, for the last five hundred years, it has not happened that any of these nations has actually overrun another country, there are various reasons to account for it.  First, the great clearance which that region made of its inhabitants during the decline of the Roman Empire, when more than thirty nations issued from it in succession; and next, the circumstance that the countries of Germany and Hungary, whence also these nations came, are now so much improved that men can live there in comfort, and consequently are not constrained to shift their habitations.  Besides which, since these countries are occupied by a very warlike race, they serve as a sort of bulwark to keep back the neighbouring Scythians, who for this reason do not venture to attack them, nor attempt to force a passage.  Nevertheless, movements on a great scale have oftentimes been begun by the Tartars, and been at once withstood by the Hungarians and Poles, whose frequent boast it is, that but for them, Italy and the Church would more than once have felt the weight of the Tartar arms.
