CHAPTER III The Ottoman and Persian Empires and the Growth of European Enterprise (1517—1770) LIKE THE Byzantine Empire, the Ottoman Turks had to divide their effective power between the Middle East and their even more important interests in the Balkans. Both empires were essentially Levantine; but they wasted their resources in continual wars against a powerful rival in Persia, from which they were estranged by deep religious differences. Just as the inconclusive Byzantine-Persian wars weakened both states and exposed them to the Arab invasion and conquest, so the inconclusive Ottoman- Persian wars of the sixteenth-eighteenth centuries weakened both and exposed them to European commercial penetration, leading eventually to their helpless manipulation by European Powers in the nineteenth century. In both the Byzantine and the Ottoman periods the possession of Iraq was disputed with Persia, and in both periods likewise the sovereign in Constantinople, being also the master of Egypt, was led by force of geographical propinquity to seek to control the opposite Arabian coast of the Red Sea; but with little permanent effect, so that in both periods the greater part of the Arabian peninsula remained practically independent of the Great Power ruling in the Levant, and was only lightly touched by its civilization.
