Decolonisation in Asia and Africa

Introduction

Decolonisation refers to the process through which colonies gained political independence from their colonial rulers. Following the Second World War, many countries in Asia and Africa achieved freedom from European colonial powers such as Britain, France, Belgium, Portugal and the Netherlands.

The decolonisation movement transformed global politics by ending centuries of colonial rule, giving rise to newly independent nations, accelerating the growth of democracy and strengthening international cooperation. It also reshaped the global balance of power and contributed to the emergence of the Non-Aligned Movement (NAM).
