Within twenty-five years after the end of the Second World War most of the countries of Asia and Africa attained their independence.
Various factors were responsible for the success of the national liberation movement in Asia and Africa.
(1) In the post-Second World War period public opinion was very much against colonial domination.
Particularly the two superpowers that emerged after the World War II were also opposed to colonialism.
(2) The imperialist countries of Europe were shattered by the World War and lost the power to hold the colonies.
(3) The growth of nationalism and the rise of national movements in Asia and Africa were important factors that made the liberation movement inevitable.
(4) The Japanese occupations of the western colonies in Asia also helped the process of decolonization.
