In early August 1972, the President of Uganda, Idi Amin, ordered the expulsion of his country's Asian minority, giving them 90 days to leave the country. At the time of the expulsion, there were approximately 80,000 individuals of South Asian descent in Uganda, of whom 23,000 had had their applications for citizenship both processed and accepted. Although the latter were ultimately exempted from the expulsion, many chose to leave voluntarily. The expulsion took place against a backdrop of Indophobia in Uganda, with Amin accusing a minority of the Asian population of disloyalty, non-integration and commercial malpractice, claims Indian leaders disputed. Amin defended the expulsion by arguing that he was giving Uganda back to the ethnic Ugandan.
Many of the expellees were citizens of the United Kingdom and Colonies and 27,200 subsequently emigrated to the United Kingdom. Of the other refugees who were accounted for, 6,000 went to Canada, 4,500 refugees ended up in India and 2,500 went to nearby Kenya. In total, some 5,655 firms, ranches, farms, and agricultural estates were reallocated, along with cars, homes and other household goods.
The presence of South Asians in Uganda was the result of deliberate choices by the British administration (1894–1962). They were brought to the Uganda Protectorate by the British to "serve as a buffer between Europeans and Africans in the middle rungs of commerce and administration". In addition, in the 1890s, 32,000 labourers from British India were brought to Southeast Africa under indentured labour contracts to work on the construction of the Uganda Railway. Most of the surviving Indians returned home, but 6,724 individuals decided to remain in the African Great Lakes after the line's completion. At the time of the expulsion, there were approximately 80,000 individuals of South Asian descent in Uganda, of whom 23,000 had had their applications for citizenship both processed and accepted. A further 50,000 were British passport holders, though Amin himself used the apparently exaggerated figure of 80,000 British passport holders in his initial expulsion speech.
