The history of Uganda between 1971 and 1979 comprises the history of Uganda during Idi Amin's military dictatorship over Uganda. The Ugandan economy was devastated by Idi Amin's policies, including the expulsion of Asians, the nationalisation of businesses and industry, and the expansion of the public sector. The real value of salaries and wages collapsed by 90% in less than a decade. The number of people killed as a result of his regime is unknown; estimates from international observers and human rights groups range from 100,000 to 500,000.
