Decolonisation occurred after World War II, leading to many colonies gaining independence due to factors such as UN support, economic pressures on empires, and the emergence of nationalist leaders. Notably, India gained independence through non-violent protest led by Mahatma Gandhi, while the creation of Israel following the war sparked ongoing conflict with Arab nations. The countries emerging from decolonisation faced numerous challenges, such as arbitrary borders, economic dependence, and the rise of dictatorships, resulting in the classification of many as 'third world' countries.
