The idea that the Mediterranean might become a French lake has, in different senses, been a preoccupation for France and for its rivals in Europe ever since Algeria became a French province by a series of fortuitous incidents--an insult offered by the dey to a French consul, his refusal to make reparation, and the occasion it afforded of diverting public attention in France from interior affairs after the Revolution of 1830. The French policy of preponderance in Egypt had only for a secondary aim the domination of the Mediterranean. The French tradition in Egypt was a relic of Napoleon's vain scheme to become emperor of the Orient even before he had made himself emperor of the West. It was because Egypt was the highway to India that under Napoleon III. the French had constructed the Suez Canal, and for the same reason England could never permit them to become masters of the Nile delta. But the possessors of Algeria could extend their coast-line of North Africa without seriously menacing the power which held Gibraltar and Malta. It was Italy which objected to a French occupation of Tunis. Algeria has never been officially a French "colony." It is in many respects administered as an integral portion of French territory, the governor-general, as agent of the central power, exercising wide jurisdiction. Although the Europeans in Algeria are less than a seventh of the population, and although the French are actually a minority of the European inhabitants--Spaniards prevailing in the west, Italians and Maltese in the east--the three departments of Constantine, Algiers and Oran are administered like three French departments. Consequently, when disturbances occurred on the borderland separating Constantine from Tunis, the French were able to say to Europe that the integrity of their national frontier was threatened by the proximity of a turbulent neighbour. The history of the relations between Tunis and France were set forth, from the French standpoint, in a circular, of which Jules Ferry was said to be the author, addressed by the foreign minister, M. Barthelemy Saint-Hilaire on the 9th of May 1881, to the diplomatic agents of France abroad. The most important point emphasized by the French minister was the independence of Tunis from the Porte, a situation which would obviate difficulties with Turkey such as had always hampered the European powers in Egypt. In support of this contention a protest made by the British government in 1830, against the French conquest of Algiers, was quoted, as in it Lord Aberdeen had declared that Europe had always treated the Barbary states as independent powers. On the other hand, there was the incident of the bey of Tunis having furnished to Turkey a contingent during the Crimean War, which suggested a recognition of its vassalage to the Sublime Porte. But in 1864, when the sultan had sent a fleet to La Goulette to affirm his "rights" in Tunis, the French ambassador at Constantinople intimated
