Almost 6 percent of the population was of Rwandan descent, comprising Hutu and Tutsi (Watutsi) ethnic groups, in 1959, but at that time, most Rwandans in Uganda were citizens. They were Bantu-speakers, culturally related to the Hima and Iru of the southwestern kingdoms of Bunyoro, Toro, and Ankole. Most Rwandans lived in Buganda, where they worked in agriculture, business, and a variety of service occupations. Most were Roman Catholics. In the early 1980s, as refugees migrated freely across national boundaries throughout East Africa, the government attempted to limit Rwandan influence by restricting those who lacked Ugandan citizenship to refugee camps and by expelling some to Tanzania. In the late 1980s, more than 120,000 Rwandans were recognized as refugees in Uganda by the UNHCR.
