In Africa, a new series of diasporas formed following the end of colonial rule. In some cases, as countries became independent, numerous minority descendants of Europeans emigrated; others stayed in the lands which had been family homes for generations. Uganda expelled 80,000 South Asians in 1972 and took over their businesses and properties. The 1990-1994 Rwandan Civil War between rival social/ethnic groups (Hutu and Tutsi) turned deadly and produced a mass efflux of refugees.
