The most powerful religious empire that the world has ever seen had suddenly sprung into existence. It stretched from the Great Wall of China to the burning sands of Tripoli, and from the Caspian Sea on the north to Abyssinia on the south. Yet this was but little more than half the territory that it soon afterwards controlled. One of its armies advanced on Constantinople. It did not fall then, but afterwards became the capital of the Mahometan power in Europe. Another took possession of the whole north of Africa, and, having consolidated its power there, under the command of their general, Tarik, they crossed the straits that separate Africa from Spain, and landing on the rocky clift of Gib-el-Tarik, or mountain of Tarik (now called Gibraltar), unfurled their green banner with golden crescent for the first time on the soil of Europe. Tarik was soon followed into Spain by his superior officer, the emir Musa. They took possession of the whole southern portion of Spain and Portugal, which in their own picturesque language, they named Andalusia, or the region of the evening. It was soon found that the whole peninsula was ripe for revolution. The Jews comprised a large proportion of the Spanish people. They were, to a great extent, the cultivators of the soil, which pursuit well repaid their labors. They were {32} then, as now, famous as merchants and money-lenders, and many of them held high positions in the government, while thousands of them were scattered in every city, town and village, as the physicians and teachers of the people. Their wrongs had been accumulating for centuries. Bigotry, envy and avarice had conspired to point them out as objects of persecution. Laws were passed which were never intended to be executed. It was expected that they would purchase a remission of the penalties by pouring their hard-earned treasures into the lap of Rome. No doubt the Jews exulted as the tide of Saracen conquest swept onward. They did not deplore a change of masters for those who would leave them in possession of civil and religious liberty. Before long the whole Iberian peninsula fell into the hands of the Mahometans. Not content with this, they crossed the Pyrenees, and took possession of that portion of France that lies to the south of the river Loire. All Central France was overrun. Castles, churches and monasteries were despoiled. For a time they held undisturbed dominion. The empire of the Saracens was then at its greatest extent. It reached from the confines of China to the Atlantic ocean, and comprised within its limits forty degrees of latitude and nearly one hundred and twenty of longitude. In Western Europe alone it stretched in an unbroken line more than a thousand miles northward from the cliffs of Gibraltar. More than thirty-six thousand cities paid tribute to the successors of Mahomet in the city of Medina.
