British forces invaded and occupied Egypt in 1882 to put down a nationalist revolution hostile to foreign interests and remained there to prevent any further threat to the khedive’s government or the possible intervention of another European power. The consequences of this were far-reaching. A permanent British occupation of Egypt required the inviolability of the Nile waters—without which Egypt could not survive—not from any African state, which did not possess the technical resources to interfere with it, but from rival European powers, which could. Consequently, the British government, by diplomacy and military maneuvers, negotiated agreements with the Italians and the Germans to keep them out of the Nile valley. They were less successful with the French, who wanted them to withdraw from Egypt.

Once it became apparent that the British were determined to remain, the French cast about for means to force the British from the Nile valley. In 1893 an elaborate plan was concocted by which a French expedition would march across Africa from the west coast to Fashoda (Kodok) on the upper Nile, where it was believed a dam could be constructed to obstruct the flow of the Nile waters. After inordinate delays, the French Nile expedition set out for Africa in June 1896, under the command of Capt. Jean-Baptiste Marchand.

As reports reached London during 1896 and 1897 of Marchand’s march to Fashoda, Britain’s inability to insulate the Nile valley became embarrassingly exposed. British officials desperately tried one scheme after another to beat the French to Fashoda. They all failed, and by the autumn of 1897 British authorities had come to the reluctant conclusion that the conquest of the Sudan was necessary to protect the Nile waters from French encroachment. In October an Anglo-Egyptian army under the command of Gen. Sir (later Lord) Horatio Herbert Kitchener was ordered to invade the Sudan. Kitchener pushed steadily but cautiously up the Nile. His Anglo-Egyptian forces defeated a large Mahdist army at the Atbara River on April 8, 1898. Then, after spending four months preparing for the final advance to Omdurman, Kitchener’s army of about 25,000 troops met the massed 60,000-man army of the Khalīfah outside the city on September 2, 1898. By midday the Battle of Omdurman was over. The Mahdists were decisively defeated with heavy losses, and the Khalīfah fled, to be killed nearly a year later.

Kitchener did not long remain at Omdurman but pressed up the Nile to Fashoda with a small flotilla. There, on September 18, 1898, he met Captain Marchand, who declined to withdraw: the long-expected Fashoda crisis had begun. Both the French and British governments prepared for war. Neither the French army nor the navy was in any condition to fight, however, and the French were forced to give way. An Anglo-French agreement of March 1899 stipulated that French expansion eastward in Africa would stop at the Nile watershed. (See Fashoda Incident.)

The early years of British rule

Having conquered the Sudan, the British now had to govern it. But the administration of this vast land was complicated by the legal and diplomatic problems that had accompanied the conquest. The Sudan campaigns had been undertaken by the British to protect their imperial position as well as the Nile waters, yet the Egyptian treasury had borne the greater part of the expense, and Egyptian troops had far outnumbered those of Britain in the Anglo-Egyptian army. The British, however, did not simply want to hand the Sudan over to Egyptian rule; most Englishmen were convinced that the Mahdiyyah was the result of 60 years of Egyptian oppression. To resolve this dilemma, the Anglo-Egyptian Condominium was declared in 1899, whereby the Sudan was given separate political status under which sovereignty was jointly shared by the khedive and the British crown, and the Egyptian and the British flags were flown side by side. The military and civil government of the Sudan was invested in a governor-general appointed by the khedive of Egypt but nominated by the British government. In reality, there was no equal partnership between Britain and Egypt in the Sudan. From the first the British dominated the condominium and set about pacifying the countryside and suppressing local religious uprisings, which created insecurity among British officials but never posed a major threat to their rule. The north was quickly pacified and modern improvements were introduced under the aegis of civilian administrators, who began to replace the military as early as 1900. In the south, resistance to British rule was more prolonged; administration there was confined to keeping the peace rather than making any serious attempts at modernization.

The first governor-general was Lord Kitchener himself, but in 1899 his former aide, Sir Reginald Wingate, was appointed to succeed him. Wingate knew the Sudan well and, during his long tenure as governor-general (1899–1916), became devoted to its people and their prosperity. His tolerance and trust in the Sudanese resulted in policies that did much to establish confidence in Christian British rule by a devoutly Muslim, Arab-oriented people.

Modernization was slow at first. Taxes were purposely kept light, and the government consequently had few funds available for development. In fact, the Sudan remained dependent on Egyptian subsidies for many years. Nevertheless, railway, telegraph, and steamer services were expanded, particularly in Al-Jazīrah, in order to launch the great cotton-growing scheme that remains today the backbone of Sudan’s economy. In addition, technical and primary schools were established, including the Gordon Memorial College, which opened in 1902 and soon began to produce a Western-educated elite that was gradually drawn away from the traditional political and social framework.

Scorned by the British officials (who preferred the illiterate but contented fathers to the ill-educated, rebellious sons) and adrift from their own customary tribal and religious affiliations, these Sudanese turned for encouragement to Egyptian nationalists, and from that association 20th-century Sudanese nationalism was born. Its first manifestations occurred in 1921, when ʿAlī ʿAbd al-Laṭīf founded the United Tribes Society and was arrested for nationalist agitation. In 1924 he formed the White Flag League, dedicated to driving the British from the Sudan. Demonstrations followed in Khartoum in June and August and were suppressed. When the governor-general, Sir Lee Stack, was assassinated in Cairo on November 19, 1924, the British forced the Egyptians to withdraw from the Sudan and annihilated a Sudanese battalion that mutinied in support of the Egyptians. The Sudanese revolt was ended, and British rule remained unchallenged until after World War II.
