The opening of the Suez Canal in 1869 introduced a fresh complication. Relations between England and France had since Waterloo been friendly, on the whole; but France had traditional interests in Egypt, which were strengthened by the fact that a French engineer had constructed the Suez Canal, and by French colonies in the Far East, to which the canal was the shortest route. Rivalry with England for the control of Egypt followed. The Dual Control, which was established in 1876, was terminated by the refusal of France to assist in the suppression of Egyptian revolts in 1882; and Great Britain was left in sole but informal possession of power in Egypt, with the responsibility for its defence against the Mahdi (1884-1885) and for the re-conquest of the Sudan (1896-1898), which is now under the joint Egyptian and British flags. Meanwhile, British expansion to the east of India, the Burmese wars, and annexation of Burma (1885) brought the empire into a contact with French influence in Siam similar to its contact with Russian in Afghanistan. Community of interests in the Far East, as well as the need of protection against the Triple Alliance of Germany, Austria, and Italy produced the _entente cordiale_ between France and Russia in 1890. Fortunately, the dangerous questions between them and Great Britain were settled by diplomacy, assisted by the alliance between Great Britain and Japan. The British and Russian spheres of action on the north-west, and the British and French spheres to the east, of India were delimited; southern Persia, the Persian Gulf, and the Malay Peninsula were left to British vigilance and penetration, northern Persia to Russian, and eastern Siam to French. Freed from these causes of friction, Great Britain, Russia, and France exert a restraining influence on the predominant partner in the Triple Alliance.
