Sudan and the Nile

British power along the Nile

In the late nineteenth century, British military and diplomatic involvement in Egypt and Sudan changed control over Nile trade, navigation and irrigation. The river became a strategic route and an economic resource administered through unequal political power.

Britain governs the Nile

The 1899 Anglo-Egyptian agreement established a condominium in Sudan, but British officials held decisive administrative power. The Nile valley was surveyed for crops, irrigation and imperial commerce. Across the country, unequal colonial administration invested in some riverine areas while governing vast rural regions through indirect rule and limited services.

One year before that agreement, on 2 September 1898, Kitchener’s British-led Anglo-Egyptian army defeated the Mahdist forces at Omdurman, near the meeting of the Blue and White Niles. The British National Army Museum records approximately 10,000 Mahdist fighters killed and 13,000 wounded, against fewer than 50 British-led army deaths. The violence that enabled colonial control must appear in the history alongside the subsequent irrigation plans.

Cotton, canals and the colonial economy

When the Sennar Dam began supplying the Gezira irrigation scheme, it helped turn Blue Nile water into cotton for international trade. British commercial interests and Sudanese tenant farmers did not occupy equal positions in the project. The tenants supplied labour on land they did not fully control, under an arrangement devised for export production. The canals remained long after colonial rule ended.

Independence did not dismantle the irrigation economy

When Sudan became independent in 1956, it inherited a state organised around the Nile’s central irrigated districts and marginalised peripheral regions. Gezira’s canals had linked British commercial cotton interests to Sudanese tenant labour, and the new government retained their export and investment geography. Later national regimes faced declining productivity, debt and political crisis. World Bank rehabilitation lending in the 1980s and reform advice in 2000 intersected with domestic programmes, but it was Sudan’s own rulers and connected business networks that determined the form of Gezira’s 2005 privatisation. A 1959 Egypt–Sudan Nile agreement also allocated flows without including other upstream countries.

Sanctions on an unequal economy

The United States imposed broad economic sanctions on Sudan in 1997, adding another constraint to an economy already marked by civil wars, uneven investment and state repression. The United States lifted most comprehensive sanctions in 2017; later targeted measures addressed Darfur and the 2023 war. Neither sanctions nor their removal resolved the deeper struggle over land, political power and essential services.

Two Sudans

South Sudan gained independence in 2011 after decades of war. New boundaries did not settle the long history of state violence and uneven development. Nile wetlands, farming and seasonal floods remained essential to communities whose lives were disrupted by later fighting.

War reaches the water plants

War between Sudan’s Armed Forces and the Rapid Support Forces erupted in April 2023. Attacks on power installations, looting and damage to treatment plants stopped water supply in many places. UNICEF later documented that only four of Khartoum State’s seventeen water-treatment plants remained operational. The violence was carried out by Sudanese armed actors; the unequal geography of investment and political authority they inherited also has a longer colonial history.
