Thus one foe was removed, but Alexius was not destined to win peace. Constant rebellions at home, and wars with the Patzinaks, the Slavs, and the Seljouks filled the next ten years. Alexius, however, was never discouraged: “eking out the lion’s skin with the fox’s hide,” he fought and intrigued, lied and negotiated, and at the end of the time had held his own and lost no more territory, while his throne was growing more secure. But in the fifteenth year of his reign a new cloud began to arise in the west, which was destined to exercise unsuspected influence, both for good and evil, on the empire. The Crusades were on the eve of their commencement. Ever since the Seljouks had taken Jerusalem in 1075, four years after Manzikert, the western pilgrims to the Holy Land had been suffering grievous things at the hands of the barbarians. But all the wrath that their ill-treatment provoked would have been fruitless, if the way to Syria had not been opened of late to the nations of Western Christendom. Two series of events had made free communication between East and West possible in the end of the eleventh century, in a measure which had never before been seen. The first of these was the conversion of Hungary, begun by St. Stephen in 1000, and completed about 1050. For the future there lay between the Byzantine Empire and Germany not a barbarous pagan state, but a semi-civilized Christian kingdom, which had taken its place among the other nations of the Roman Catholic faith. Communication down the Danube, between Vienna and the Byzantine outposts in Bulgaria, became for the first time possible, and ere long the route grew popular. The second phenomenon which made the Crusades possible was the destruction of the Saracen naval power in the Central Mediterranean. This was carried out first by the Pisans and Genoese, whose fleets conquered Corsica and Sardinia from the Moslems, and then by the Normans, whose occupation of Sicily made the voyage from Marseilles and Genoa to the East safe and sure. Four new maritime powers—the Genoese, Pisans, and Normans in the open sea, and the Venetians in the Adriatic—had developed themselves into importance, and now their fleets swept the waters where no Christian war-galleys save those of Byzantium, had ever been seen before.
