The Soudan is a vast tract of Africa, stretching from Egypt on the north to the Nyanza Lakes on the south, and from the Red Sea on the east to the farthest boundary of Darfur on the west. Khartoum, at the junction of the Blue and White Niles, is about equally distant from the northern boundary of Egypt (the Mediterranean) and from the southern limit of the Khedive's Equatorial dominions, Lake Victoria Nyanza, and Uganda. From Khartoum to the ports of Souakim and Massowah, on the Red Sea, the eastern limit of the Soudan, the distance is about 480 miles, and to the westward limit, which is the most indefinite of all, but is generally fixed at the western boundary of Darfur, it is nearly 800 miles. This country is as large as India. It extends 1,600 miles in one direction and 1,300 in another. There were at this time neither railways, canals, nor, except the Nile at some periods of the year, navigable rivers, and the only roads were camel tracks. The sovereignty of the Soudan was first seized by Egypt in the year 1819, when Mehemet Ali, hearing of the anarchy prevailing there, and wishing to introduce the benefits of a regular government and of civilization, and at the same time to occupy his troops, ordered his son Ismail, with a large army of regulars and irregulars, to invade the country. Ismail reached Khartoum, and for a time governed the Soudan, but he and all his followers were burnt alive by a native ruler, who first made them drunk at his own table and then burned the house over their heads. For this a terrible vengeance was taken, and Egyptian sovereignty was established over Sennar and Kordofan. In 1856 the Viceroy, Said Pasha, visited the Soudan, and almost decided to abandon the country, but desisted in deference to the representation of the sheikhs and notables, who laid great stress upon the anarchy which would result from such an abandonment. He decreed reforms, most of which appear to have been punctually neglected. One Governor-General succeeded another, their chief duties being border-warfare with Abyssinia and the suppression of the rebellions which periodically broke out. In 1866 Massowah and Souakim were given to Egypt by the Sultan of Turkey. In 1870 Sir Samuel Baker set out to conquer the Equatorial Provinces, returning in 1873. Colonel Gordon, afterwards Gordon Pasha, was appointed Governor-General of the Equatorial Provinces in the following year.
