# Decolonisation and New Nations

Between 1945 and the 1970s, dozens of colonies became independent states. Movements used negotiations, mass campaigns and armed struggle, often together. Ending colonial rule changed political authority, while inherited borders and economic ties could still affect the new states.

## Ready when they can

- Name two routes to independence and say what each demanded of the colonial power
- Explain how an inherited colonial border could contribute to disputes without making conflict inevitable
- Give one country's independence date and say which power it became independent from
- Say why political independence did not automatically bring economic independence

## Lesson: New flags, old borders

Decolonisation means ending colonial rule. Between 1945 and the 1970s, dozens of colonies became independent states. Negotiations sought agreement to transfer authority. Mass campaigns used strikes, boycotts and marches to pressure colonial rulers to leave. Armed struggles involved fighting colonial forces. These methods often overlapped; countries did not all follow the same route.

Some colonial borders divided communities or placed several communities under one government. After independence, people could dispute territory, representation or access to relatives across a border. These problems did not make war inevitable. Governments and communities could negotiate and cooperate. A border was one influence on events, not a complete explanation of them.

**Example.** India became independent from Britain in 1947 after mass campaigns and negotiations. Partition created India and Pakistan amid violence and displacement. Nigeria became independent from Britain in 1960 after nationalist campaigning and negotiations. Algeria became independent from France in 1962 after the war of 1954 to 1962 and a negotiated settlement. These cases show different combinations of methods.

Political independence gave a state authority over its government. Economic choices could still be limited by foreign debts, trade contracts, dependence on a few exports or foreign ownership of businesses. These ties varied between countries and could remain after negotiations or armed struggle. Later debt alone therefore cannot tell you how independence was won.

The Cold War topic showed how outside powers sought influence. The United States and Soviet Union offered aid and arms and intervened in some conflicts. Independence movements and new states also pursued their own goals. Some sought support from a bloc. Others sought non-alignment, avoiding commitment to either superpower. Outside pressure mattered without explaining every decision.

**Recap.** Movements combined different methods to end colonial rule. Political independence did not automatically remove inherited borders, economic constraints or outside pressure.
