Independence day was a beginning, not an end. Flags rose, anthems played and new leaders spoke of freedom, but every new state inherited borders, economies, armies and schools designed for someone else's purposes. How those inheritances shaped what came next is one of the most argued questions in modern history.
The Congo crisis
Belgium's departure from the Congo in 1960 became the starkest warning. Belgium had done little to prepare Congolese people for self-government; at independence the country had fewer than twenty university graduates by most counts. At the independence ceremony on 30 June 1960, King Baudouin praised the colonial work of Leopold II, and Prime Minister Patrice Lumumba answered with a fierce speech about the humiliations Congolese had suffered. Within days the army mutinied and Belgian troops returned. In July the mineral-rich province of Katanga declared secession with Belgian support. The UN sent a large force. Lumumba, who had turned to the Soviet Union for help, was deposed, handed to his enemies in Katanga and killed in January 1961. A Belgian parliamentary inquiry in 2001 found Belgium morally responsible for Lumumba's death, and the government apologized in 2002. Joseph Mobutu, backed by the United States, seized power in 1965 and ruled for 32 years.
Did colonialism develop or underdevelop?
Economists and historians still debate colonialism's economic effects. In How Europe Underdeveloped Africa (1972), the Guyanese historian Walter Rodney argued that colonial rule drained Africa's wealth and shaped its economies around exporting raw materials. Dependency theorists argued that former colonies stayed poor because they were locked into exporting raw materials to richer countries on unequal terms. Critics of dependency theory point to East Asian former colonies, such as South Korea and Taiwan, that grew rich by exporting to the West, and they put more weight on policies chosen after independence.
A third approach, associated with the economists Daron Acemoglu, Simon Johnson and James Robinson, who shared the 2024 Nobel Prize in economics, focuses on institutions. They argue that colonizers built institutions protecting property and rights where they settled in large numbers, and extractive institutions where they did not. Acemoglu, Johnson and Robinson argue that colonial institutions shaped prosperity long after independence. Their work has been challenged on its data and methods, but it moved the debate from whether colonialism mattered to how.
Money and migration
Economic ties often outlasted political ones. France kept close links with many former African colonies through defense agreements, advisers and the CFA franc, a currency created in 1945 and long guaranteed by the French Treasury. Critics called the system Françafrique and saw it as neocolonialism; supporters stressed the currency's stability. In 2019 France and eight West African states agreed to reform the CFA franc, ending the requirement to keep half their reserves in Paris and announcing a new name, though the change has been slow.
Empire also came home. Britain's Nationality Act of 1948 gave citizenship to people across the empire, and migrants from the Caribbean, South Asia and Africa helped rebuild British cities. France, the Netherlands, Belgium and Portugal saw similar movements. Former colonial subjects became citizens and voters in the old metropoles, making the colonial past part of national politics there.
Reckonings
Recent decades have brought public reckonings. Germany acknowledged in 2021 that its killings of Herero and Nama people in Namibia from 1904 to 1908 were genocide, and offered development funds, though many Herero and Nama leaders rejected the deal because they had not negotiated it directly. Museums have faced similar questions. European collections hold hundreds of thousands of objects from former colonies, some bought, some given and many seized in war. In 2017 President Macron promised to create conditions for returning African heritage and commissioned two scholars, Felwine Sarr and Bénédicte Savoy. The Sarr-Savoy report of 2018 recommended returning objects taken from Africa without consent. In 2021 France returned 26 royal treasures, taken from Abomey by French troops in 1892, to Benin. Critics of wholesale return argue that great museums let people everywhere see the art of all cultures side by side. Supporters reply that people who never consented to the taking deserve the right to decide where their heritage belongs.
Worked example: weighing India's railways
Defenders of empire often point to India's railways, tens of thousands of kilometers of track built under British rule. Critics answer that the lines were laid largely to move troops and to carry raw cotton to the ports and British goods inland. Many were built by private British companies under a guarantee: investors earned a fixed return of about 5 percent, paid from Indian taxes when profits fell short, which encouraged costly construction.
Yet economic historians have also measured real gains. The economist Dave Donaldson, using district records, estimated that railways raised real agricultural incomes by roughly 16 percent by cutting trade costs, and later work with Robin Burgess found that districts connected by rail suffered less in famines. Do such findings vindicate colonial rule? Not by themselves. The useful question is the comparison with what might have happened otherwise: what a self-governing India could have built with the same resources, and who decided how the costs and benefits were shared. Weighed this way, the historian need not choose between celebrating and condemning. The job is to measure the gains, ask who paid and who benefited, and remember that people denied any say in such decisions were denied something no railway could replace.
