Evolution of Nation States

This lesson traces the evolution of nation states from the colonial era to the present day. It examines how borders have been drawn, redrawn, erased and contested through processes of colonialism, decolonisation, partition, reunification and state failure. Understanding this historical context is essential for explaining contemporary geopolitical tensions. This lesson addresses the Edexcel Enquiry Question: "What is the relationship between globalisation and sovereignty?"

The Colonial Era and Border Drawing

European Colonialism (15th–20th Centuries)

European colonial powers divided much of Africa, Asia, the Middle East and the Americas into colonies, protectorates and spheres of influence. Colonial borders were drawn to serve European economic and strategic interests, with almost no regard for pre-existing political structures, ethnic boundaries or cultural identities.

Key characteristics of colonial borders:

• Geometric lines: Approximately 44% of African borders follow lines of latitude or longitude — straight lines drawn on maps in European capitals. The border between Algeria and Mali, for instance, is a perfectly straight line across the Sahara.
• Resource extraction logic: Borders were designed to maximise colonial access to resources. Belgium's Congo was drawn to encompass vast mineral wealth; British Nigeria combined diverse ethnic groups to create a single administrative unit for efficient resource extraction.
• Divide and rule: Colonial powers deliberately fragmented some ethnic groups and combined others to prevent unified resistance. The British divided the Somali people across five territories (British Somaliland, Italian Somaliland, French Somaliland, Ethiopian Ogaden and Kenya's Northern Frontier District).
• Arbitrary groupings: The borders of states like Iraq, Syria, Nigeria and India combined peoples with no shared identity, language or history, creating the conditions for post-independence conflict.

The Berlin Conference (1884–1885)

The Berlin Conference formalised the "Scramble for Africa". Representatives of 14 European nations (and the USA) met in Berlin to partition Africa. Key outcomes:

• Africa was divided into approximately 50 colonial territories, later becoming independent states.
• The conference set the principle that colonial claims required "effective occupation" — leading to a rush to establish control over territories.
• No African representatives were invited or consulted.
• The conference is the single most important event in understanding why Africa's borders often bear no relation to ethnic or cultural geography.

Colonial Power	Key African Territories	Legacy Border Issues
Britain	Nigeria, Ghana, Kenya, South Africa, Sudan, Egypt	Nigeria: 250+ ethnic groups in one state; Sudan: North-South division leading to 2011 split
France	Algeria, Senegal, Mali, Congo, Chad, Madagascar	Straight-line Saharan borders; ongoing instability in the Sahel
Belgium	Congo, Rwanda, Burundi	Exploitation of Hutu-Tutsi divisions; 1994 Rwandan genocide
Portugal	Angola, Mozambique, Guinea-Bissau	Prolonged independence wars; Cold War proxy conflicts
Germany	Tanganyika, Namibia, Cameroon	Divided ethnic groups; Namibia's Herero genocide (1904–08)

Decolonisation (1945–1990s)

After World War II, a wave of decolonisation swept across Asia, Africa, the Middle East and the Caribbean. The old colonial empires — exhausted by war, facing growing nationalist movements, and pressured by the USA and USSR (both anti-colonial for different reasons) — withdrew from their colonies.

The Principle of Uti Possidetis

When colonies gained independence, they faced a critical question: should the colonial borders be redrawn to reflect ethnic and cultural realities, or should they be maintained?

The Organisation of African Unity (OAU, now the African Union) adopted the principle of uti possidetis juris ("as you possess, so you may possess") in 1964, affirming that colonial borders would be respected as the borders of new independent states. The rationale was pragmatic: redrawing borders based on ethnicity would trigger endless disputes, wars and further instability. But the consequence was that the arbitrary colonial borders were locked in, perpetuating internal divisions.

Exam Tip: Uti possidetis is a concept that few students know, but it demonstrates sophisticated understanding of how colonial legacies shape the modern political map. Using it in an essay about African or Middle Eastern borders will earn strong analytical marks.

Partition: Dividing States Along Ethno-Religious Lines

Partition involves the deliberate division of a territory into separate states, usually along ethnic, religious or ideological lines. It is one of the most traumatic processes in political geography.

India and Pakistan (1947)

The partition of British India into Hindu-majority India and Muslim-majority Pakistan (including East Pakistan, now Bangladesh) is the most significant partition of the 20th century:

• The boundary was drawn by Sir Cyril Radcliffe, a British lawyer who had never visited India. He was given just five weeks to draw the border through Punjab and Bengal.
• Partition triggered the largest mass migration in history: approximately 15 million people crossed the new borders — Muslims moving to Pakistan, Hindus and Sikhs moving to India.
• Between 500,000 and 2 million people were killed in communal violence during partition.
• The partition created the Kashmir dispute, which remains unresolved and has caused three wars.
• East Pakistan achieved independence as Bangladesh in 1971 after a brutal war in which an estimated 300,000–3 million people died.
