Ever since its conquest by the armies of Muḥammad ‘Alī Pasha in 1820, Sudan (the Republic of Sudan today) has been subjugated to colonial rule by foreign powers—first by the Ottoman-Egyptian regime from 1821 to 1885, then by the British (nominally the Anglo-Egyptian “Condominium”) from 1899 to 1955. Consequently, modern Sudanese history came to be characterized by the emergence of a series of anticolonial popular struggles, such as the Mahdist movement (1881–1898), the 1924 Revolution, and other political movements in the 1940s and 1950s. In spite of apparent differences in style, method, and ideological background, these were essentially based on the energy of the masses aspiring for liberation from colonial rule.
The development of the national liberation movement in Sudan was a complicated process, since the modern Sudanese state itself was an artificial colonial state, and it was never self-evident what the “Sudanese nation” was. Building solidarity among peoples of different cultural and religious backgrounds within Sudan (such as the mainly Arab Muslim population in the north and peoples of different backgrounds in the south and the Nuba Mountains) turned out to be crucial to the anticolonial struggle. Because of the colonial situation which prevailed in the Nile Valley after the 1880s (Egypt itself was occupied by the British in 1882), the idea of a regional (if apparently contradictory) coordination of “Sudanese nationalism” and the cause of the “unity of the Nile Valley” coexisted. Finally, since colonialism inevitably had its socioeconomic dimensions, a conflict of interests between the privileged local elites (tribal and religious leaders) and the general masses emerged, leading to a struggle over who would represent the “Sudanese nation.” The independence of the country in 1956 did not put an end to the question of Sudanese nationalism, since the colonial nature of the modern Sudanese state remained unchanged, and the popular struggle against oppressive state apparatus and social injustice continued even after independence. Various elements of civil society, including trade unions, students, and women, called for a democratic transformation of the Sudanese state. Peoples of the politically and economically “marginalized” areas in Sudan (such as the South and the Nuba Mountains) rose up in protest against underdevelopment, leading eventually to the emergence of Sudan People’s Liberation Movement (SLPM) in the 1980s, which advocated the vision of “New Sudan”—a type of “Sudanese nationalism,” so to speak, based on the aspirations of marginalized areas. Although, with the independence of the South in 2011 (a development which was not originally anticipated by the Sudan People’s Liberation Movement [SPLM] itself) the modern Sudanese state (as it used to be known) ceased to exist, this does not mean that the heritage of various anticolonial struggles in Sudan has been meaningless. Rather, it constitutes a common property, so to speak, for the peoples in the region (though now divided between different states), and serves as a source of historical lessons and political inspiration for future generations.
