CHAPTER XX
THE CRUSADES STIR THE EUROPEAN MIND
What Brought About the Crusades.—We have learned from the former chapters that the Arabs had spread their empire from the Euphrates to the Strait of Gibraltar, and that the Christian and Mohammedan religions had compassed and absorbed the entire religious life over this whole territory. As Christianity had become the great reforming religion of the western part of Europe, so Mohammedanism had become the reforming religion of Asia. The latter was more exacting in its demands and more absolute in its sway than the former, spreading its doctrines mainly by force, while the former sought more to extend its doctrine by a leavening process. Nevertheless, when the two came in contact, a fierce struggle for supremacy ensued. The meteorlike rise of Mohammedanism had created consternation and alarm in the Christian world as early as the eighth century. There sprang up not only fear of Islamism, but a hatred of its followers.
After the Arabian Empire had become fully established, there arose to the northeast of Bagdad, the Moslem capital, a number of Turkish tribes that were among the more recent converts to Mohammedanism. Apparently they took the Mohammedan religion as embodied in the Koran literally and fanatically, and, considering nothing beyond these, sought to propagate the doctrine through conquest by sword. They are frequently known as Seljuks. It is to the credit of the Arabs, whether in Mesopotamia, Africa, or Spain, that their minds reached beyond the Koran into the wider ranges of knowledge, a fact which tempered their fanatical zeal, but the Seljuk Turks swept forward with their armies until they conquered the Byzantine Empire of the East, the last branch of the great Roman Empire. They had also conquered Jerusalem and taken possession of the holy sepulchre, to which pilgrimages of Christians were made annually, and aroused the righteous indignation of the Christians of the Western world. The ostensible purpose of the crusades was to free Palestine, the oppressed Christians, and the holy sepulchre from the domination of the Turks.
