Decolonisation is the undoing of colonialism. Colonialism is a process of a nation establishing and maintaining its dominations of overseas territories. The concept of decolonisation, in particular, applies to the dismantlement of European colonies in Africa and Asia towards the second half of the 20th century.

What is the scope of Decolonization?

The very core of decolonisation is the right to self-determination as a fundamental right identified by the United Nations, which paves the way for independence along with other methods of decolonization.

The United Nations Special Committee on Decolonization has stated that there is no other alternative for the coloniser but to allow a process of self-determination.

The process of decolonisation may involve nonviolent revolutions or violent revolutionary wars by pro-independence groups. It may be intranational like the Indian Independence Struggle or may involve the intervention of foreign powers as was the case during the liberation of Bulgaria when the Russian Empire intervened to free it from the Ottoman Empire.

Along with these examples, there have been cases of particularly active periods of decolonization during modern times such as the breakup of the Spanish Empire in the 19th century, Abolition of the Ottoman Empire post-World-War I, dismantlement of the British, French, Dutch and Japanese Colonial Empires after World War II and the dissolution of the Soviet Union at the end of the Cold War.

What are the methods and stages of decolonisation?

World opinion began favouring the idea of decolonisation following the end of World War I. The Leauge of Nations (Dissolved on April 20, 1946) was the first international body that took a collective effort towards decolonisation. A number of mandates were created for this purpose but these were interpreted as mere redistribution of control over the former colonies to that of other colonial powers at the time, the notable example being German colonies in Africa being divided among France and Britain.

It was the devastation following World War II when the colonial powers on their own accord began taking steps towards decolonisation. As they had other priorities such as rebuilding their own countries, there was little finance or enthusiasm for military action to hold into overseas territories against their will

Through referendums, the dependent territories have chosen to retain their dependent status as was the case of Gibraltar and French Guiana. Colonial powers have at times favoured decolonisation in order to rid themselves of the financial and military burdens in light of independence movements that grew in the colonies

The final phase of decolonization may concentrate on handing over responsibility for foreign relations, security and soliciting and de jure recognition for the new sovereignty. However even following the recognition of statehood a degree of continuity can be maintained through bilateral treaties between now equal governments, such as military training, mutual protection pacts etc.
