Interior East Africa (1936–1947 CE): Global War, Colonial Transitions, and Emerging Nationalism

Between 1936 and 1947, Interior East Africa experienced the profound impacts of the Second World War, significant colonial realignments, increased nationalist activism, and shifts in international attitudes toward empire and independence.

Ethiopia: Italian Occupation and Restoration of Independence

In 1935–1936, Italy under Benito Mussolini invaded and occupied Ethiopia, overthrowing Emperor Haile Selassie, who fled into exile in Britain. Italian occupation was marked by harsh repression, resistance movements, and economic exploitation. Ethiopia, Eritrea, and Italian Somaliland were merged into Italian East Africa (Africa Orientale Italiana).

Resistance within Ethiopia, however, never ceased. Patriotic guerrillas, including leaders like Ras Abebe Aregai and Belay Zeleke, maintained fierce opposition to Italian rule. By 1941, aided by British Commonwealth forces, Ethiopian patriots succeeded in expelling the Italians. Haile Selassie triumphantly returned to Addis Ababa on May 5, 1941, restoring Ethiopia’s independence and sovereignty, although the post-war period brought challenges in reconstruction, political consolidation, and regional integration.

British East Africa during World War II

Throughout the Second World War, the British colonies—Kenya, Uganda, and Tanganyika—became vital strategic bases. Britain mobilized tens of thousands of African soldiers as part of the King's African Rifles (KAR), who fought prominently in the East African Campaign (1940–1941) against Italian forces, notably in Ethiopia, Eritrea, and Somalia.

Colonial authorities introduced forced labor and intensified resource extraction to support the war effort, causing widespread hardship but also stimulating urbanization, industrial growth, and a significant demographic shift toward urban centers such as Nairobi, Kampala, and Dar es Salaam.

Intensifying Colonial Administration and Economic Transformation

Post-war economic policies further entrenched export-oriented agriculture. Uganda Protectorate saw expanded cotton and coffee production, primarily in Buganda and Busoga, benefiting a rising class of prosperous Baganda landowners. In Kenya Colony, European settlers strengthened their political and economic dominance, particularly in the fertile White Highlands, deepening resentment among indigenous groups like the Kikuyu, Kalenjin, and Maasai.

In Tanganyika, the British promoted sisal and cotton production, yet severely limited local political participation, increasing frustrations that would fuel later nationalist movements.

Sudan: Shifting Colonial Policies and Southern Marginalization

In Anglo-Egyptian Sudan, the British pursued distinct policies in the north and south. Southern Sudanese—largely Dinka, Nuer, Shilluk, Zande, and Bari—experienced intensified isolation under the British "Southern Policy," intended to limit Islamic influence and preserve African cultural identities. These measures, however, entrenched marginalization and economic underdevelopment, laying foundations for later internal divisions and tensions.

Rwanda and Burundi under Belgian Mandate: Deepening Ethnic Division

Belgian control of Ruanda-Urundi reinforced ethnic divisions by formalizing and exploiting the social hierarchies between Tutsi and Hutu populations. Identity cards explicitly labeled ethnic groups from the 1930s onwards, deepening socio-political cleavages. The Catholic Church expanded its influence, further shaping political dynamics. Belgian policies entrenched inequality and resentment, sowing seeds for future conflicts.

Nyasaland and Northern Rhodesia: Increasing Labor Migration and Political Awareness

In Nyasaland (modern Malawi) and Northern Rhodesia (modern Zambia), British economic policies intensified dependence on cash-crop agriculture (tobacco in Nyasaland, copper mining in Northern Rhodesia). Economic hardships pushed many young men into migrant labor, notably in South African mines and Rhodesian plantations, generating wealth for European companies but exacerbating local social disruption and economic exploitation. Exposure to ideas abroad facilitated early nationalist consciousness, leading to increased demands for political rights upon their return.

The Impact of WWII on Colonial Policy and Nationalism

World War II dramatically shifted global attitudes toward colonialism, as the rhetoric of freedom and self-determination contrasted sharply with colonial realities. African veterans returning from military service abroad became pivotal figures in early nationalist movements, applying the political lessons and organizational skills acquired during wartime service.

Emergence of Nationalist Movements and Leaders

Nationalist movements intensified dramatically in this period:

• In Kenya, leaders such as Jomo Kenyatta became prominent, advocating political representation, economic rights, and cultural dignity, laying the foundations for future resistance such as the Mau Mau movement.

• In Uganda, increased education and economic differentiation contributed to the rise of political awareness, though nationalist movements remained localized until after 1945.

• In Tanganyika, Julius Nyerere emerged in the late 1940s, soon to become a central figure promoting a unified nationalist movement.

• In Sudan, the period saw early seeds of nationalism among northern and southern elites, influenced by anti-colonial sentiments elsewhere.

The Post-War International Context: Towards Decolonization

The formation of the United Nations (1945) and its mandate system encouraged international accountability in colonial administration. Ethiopia's regained independence became symbolic, encouraging anti-colonial sentiments across the continent. Globally, attitudes toward colonization shifted, creating international pressure for reforms and eventual independence.

Long-Term Consequences and Historical Significance

The period 1936–1947 thus proved transformative, marked by:

• The destabilizing yet galvanizing impact of World War II on regional politics, economics, and societies.

• The restoration of Ethiopian sovereignty, symbolizing resistance to European colonialism.

• Heightened exploitation of colonial economies and societies, generating intensified anti-colonial resistance.

• Formation and growth of nationalist movements across the region, influenced by war-time experiences and shifting global attitudes toward colonial rule.

• Increased international scrutiny and eventual erosion of legitimacy for European colonial systems.

This era laid critical groundwork for the rapid escalation of nationalist struggles and subsequent independence movements that dominated Interior East Africa's political landscape in subsequent decades.
