Nationalist and Independence Movements After World War II

Core idea

World War II broke the European empires from two directions at once. The war drained the imperial powers of money and military strength, and it discredited the moral claim that Europeans were fit to rule others. Meanwhile, colonized peoples — many of whom had fought in the war — pressed harder than ever for self-determination. The result was the fastest collapse of empire in history: between 1947 and the 1960s, dozens of new nations were born across Asia and Africa.

Why it matters

Decolonization redrew the political map of the planet. It nearly tripled the membership of the United Nations and created the modern "Global South." But independence was not the same as stability. Borders drawn by departing colonizers ignored ethnic and religious realities, leaving partitioned families, contested territories like Kashmir, and fragile states. The unfinished business of decolonization still drives conflicts today.

Two paths to independence

Independence movements ran along a spectrum. Gandhi's India shows the nonviolent path: mass civil disobedience, marches like the 1930 Salt March, and hunger strikes that made colonial rule politically unsustainable. Other movements turned to armed struggle. Recognizing which path a movement took helps explain how stable the new state became — and Gandhi's methods directly inspired later activists, including Martin Luther King Jr.

The problem of inherited borders

A useful test for any new nation: who drew the borders, and did the people inside them agree? European imperialism divided Africa "in random ways." When colonizers drew lines for their own convenience, the new states inherited ethnic divisions that often turned into conflict.

Example

Compare two outcomes of the same process. India's independence in 1947 came with partition — and the violent displacement of millions as Hindus and Muslims crossed new borders. South Africa's transition in 1994 came after nearly 27 years of Mandela's imprisonment and decades of protest, yet produced a negotiated, multiracial democracy. Both were "independence" stories, but the contrast shows that how a movement ends — through hasty partition or through patient negotiation — shapes the nation that follows.
