Decolonisation

Core Definition (BLUF)

Decolonisation denotes the political process by which former colonial territories achieved formal sovereignty from European imperial powers, concentrated between 1945 and the 1980s. As a historical event it dismantled the territorial empires of Britain, France, the Netherlands, Belgium, Portugal, and Spain. As an ongoing political and theoretical concept it encompasses claims about economic neo-colonialism, epistemic hierarchies, cultural imperialism, and the structural legacies of colonial rule in the international system. Decolonisation is central to understanding the Global North/Global South divide, the politics of Non-Alignment and multipolarism, and the grievance framing exploited by both Russian and Chinese information operations targeting African, Latin American, and Middle Eastern audiences.

Historical Phases

Phase	Period	Key Events
Post-WWII wave	1945–1960	Indian independence (1947); Indonesia (1949); Sudan, Morocco, Tunisia, Ghana (1956–1957); much of sub-Saharan Africa (1960 “Year of Africa”)
Anti-Portuguese wave	1960–1975	Angola, Mozambique, Guinea-Bissau (1974–1975, post-Carnation Revolution)
Settler-state wave	1965–1994	Algeria (1962), Zimbabwe/Rhodesia (1980), Namibia (1990), South Africa (1994)
Caribbean / Pacific	1960–1983	Trinidad (1962), Grenada (1974/overthrown 1983), Vanuatu (1980)

The United Nations served as the primary institutional vehicle — UN General Assembly Resolution 1514 (1960, “Declaration on the Granting of Independence to Colonial Countries and Peoples”) established decolonisation as a norm of international law.

Theoretical Significance in IR

Decolonisation produced fundamental structural changes to the international system:

1. State proliferation: the number of UN member states expanded from 51 (1945) to 117 by 1970. This rewrote the arithmetic of international organisations and gave the Global South majority voting power in the UNGA — exploited immediately in the New International Economic Order (NIEO) campaign of the 1970s.

2. Self-determination as norm: decolonisation embedded uti possidetis juris (colonial borders = post-independence borders) and the right of peoples to self-determination as competing principles, creating enduring tensions in post-colonial conflicts.

3. Non-Alignment: the 1955 Bandung Conference and 1961 founding of the Non-Aligned Movement were the collective diplomatic expression of decolonised states — structurally anti-hegemonic, exploited by both Cold War blocs and by revisionist powers in the post-Cold War period. See Non-Alignment.

4. Dependency critique: the structural asymmetries inherited from colonial rule — commodity-export dependence, technology transfer barriers, terms-of-trade deterioration — became the empirical basis for Dependency Theory and World-Systems Theory.

Neo-Colonialism and Structural Power

Kwame Nkrumah (Neo-colonialism: The Last Stage of Imperialism, 1965) coined the concept: formal sovereignty coexists with effective subordination through economic control, debt, technology dependence, and military pressure exercised by former colonisers and the US. The critique prefigures contemporary discussions of debt-trap diplomacy, infrastructure dependency, and the terms on which developing states access global capital.

Contemporary relevance: PRC and Russian information operations in Africa systematically deploy neo-colonialism framing to delegitimise French, US, and EU presence — operationalising decolonial discourse as a Cognitive Warfare instrument. The Wagner/Africa Corps deployment across the Sahel has been successfully packaged as “anti-colonial partner” positioning, exploiting accumulated anti-French sentiment from the colonial and post-colonial eras.

Key Connections

• Global North — the structural counterpart; decolonisation produced the Global South without eliminating structural asymmetries
• Dependency Theory — the political-economy critique of post-independence development trajectories
• World-Systems Theory — systemic extension of the dependency framework
• Non-Alignment — the diplomatic strategy of formally sovereign post-colonial states
• Active Measures / Cognitive Warfare — exploitation of anti-colonial discourse as an IO instrument
• Sahel — theatre of active decolonial discourse weaponisation
• DR Congo Conflict — ongoing legacy of Belgian colonial borders and resource extraction patterns
• Belt and Road Initiative — neo-colonialism critique applied to Chinese infrastructure lending
