the empire's Balkan provinces that led to the devastating Russo-Turkish War (1877–78) and the establishment of the Ottoman Public Debt Administration in 1881, the importance for Britain of the sureties regarding the Ottoman revenues from Egypt and Sudan increased. Combined with the much more important Suez Canal which was opened in 1869, these sureties were influential in the British government's decision to occupy Egypt and Sudan in 1882, with the pretext of helping the Ottoman-Egyptian government to put down the ʻUrabi revolt (1879–1882). Egypt and Sudan (together with Cyprus) nominally remained Ottoman territories until 5 November 1914, when the British Empire declared war against the Ottoman Empire during World War I. In 1869, Abdulaziz received visits from Eugénie de Montijo, Empress consort of Napoleon III of France and other foreign monarchs on their way to the opening of the Suez Canal.
