The Arabian tribes and Berber communities of Algeria and Tunis, which had more or less remained under the suzerainty of the Sultan, were no longer amenable to him after the French conquest. The Pasha of Egypt, by setting up as an independent Sovereign, and founding the hereditary dynasty of the Khedives, deprived the Ottoman dominion of Egypt, where the Arabs were not very numerous, but had played an important part in the development of Islam. The Italian conquest took away from Turkey the last province she still owned in Africa. Finally, when the late war broke out, England deposed the Khedive Abbas Hilmi, who was travelling in Europe and refused to go back to Egypt. She proclaimed her protectorate over the Nile valley, and, breaking off the religious bond that linked Egypt with the Ottoman Empire, she made Sultan of Egypt, independent of the Sultan of Constantinople, Hussein Kamel, uncle of the deposed Khedive, who made his entry into Cairo on December 20, 1914. The Turks, however, kept possession of the Holy Places, Mecca and Medina, which they garrisoned and governed. This sovereignty was consolidated by the railway of the pilgrimage. The investiture of the Sherif of Mecca was still vested in them, and they chose the member of his family who was to succeed him, and who was detained as a hostage at Constantinople. But after the failure of the expedition against the Suez Canal during the late war, and at the instigation of England, the Sherif, as we shall see, proclaimed himself independent, and assumed the title of Melek, or King of Arabia. On the other hand, the province of the Yemen, lying farther south of the Hejaz, has always refused to acknowledge the authority of Constantinople, and is practically independent. Lastly, at the southern end of the Arabian peninsula, the English have held possession of Aden since 1839, and have extended their authority, since the opening of the Suez Canal in 1869, over all the Hadramaut. All the sheiks of this part of Arabia along the southern coast, over whom the authority of Turkey was but remotely exercised and was practically non-existent, naturally accepted the protectorate of England without any difficulty, in return for the commercial facilities she brought them and the allowances she granted them, and in 1873 Turkey formally recognised the English possession of this coast. On the eastern coast of the Arabian peninsula the territory of the Sultan of Oman, or Maskat, lying along the Persian Gulf, has been since the beginning of the nineteenth century under the authority of the Viceroy of India. This authority extends nowadays over all the territories lying between Aden and Mesopotamia, which are in consequence entirely under English sway. Moreover, the English have proclaimed their protectorate over the Sheik of Koweit.
