Suddenly, these Arab tribes, under the excitement of the new Mussulman creed, burst forth of the unknown East. They take the Eastern Empire in the rear; by such a rear attack as the world never saw before or since; they cut it in two; devour it up: and save Europe thereby. That may seem a strange speech. I must explain it. I have told you how the Eastern Empire and its military position was immensely strong; that Constantinople was a great maritime base of operations, mistress of the Mediterranean. What prevented the Romans from reconquering all the shores of that sea, and establishing themselves in strength in the Morea, or in Sicily, or in Carthage, or in any central base of operations? What forced them to cling to Constantinople, and fight a losing campaign thenceforth. Simply this; the Mussulman had forced their position from the rear, and deprived them of Syria, Egypt, Africa. But the Teutons could not have opposed them. During the 7th century the Lombards in Italy were lazy and divided; the Goths in Spain lazier and more divided still; the Franks were tearing themselves in pieces by civil war. The years from A.D. 550 to A.D. 750 and the rise of the Carlovingian dynasty, were a period of exhaustion for our race, such as follows on great victories, and the consequent slaughter and collapse. This was the critical period of the Teutonic race; little talked of, because little known: but very perilous. Nevertheless, whatever the Eastern Empire might have done, the Saracens prevented its doing; and if you hold (with me) that the welfare of the Teutonic race is the welfare of the world; then, meaning nothing less, the Saracen invasion, by crippling the Eastern Empire, saved Europe and our race.
