For decades, many nations in Africa have suffered civil wars and ethnic strife, thus generating a massive number of refugees of many different nationalities and ethnic groups. The division of Africa into European colonies in 1885, along which lines the newly independent nations of the 1950s and 1960s drew their borders, has been cited as a major reason why Africa has been so plagued with intrastate warfare. The number of refugees in Africa increased from 860,000 in 1968 to 6,775,000 by 1992. By the end of 2004, that number had dropped to 2,748,400 refugees, according to the United Nations High Commission for Refugees. (That figure does not include internally displaced persons, who do not cross international borders and so do not fit the official definition of refugee.)
Many refugees in Africa cross into neighboring countries to find haven; often, African countries are simultaneously countries of origin for refugees and countries of asylum for other refugees. The Democratic Republic of Congo, for instance, was the country of origin for 462,203 refugees at the end of 2004, but a country of asylum for 199,323 other refugees.
Countries in Africa from where 5,000 or more refugees originated as of the end of 2004, arranged in descending order of numbers of refugees are listed below. The largest number of refugees are from Sudan and have fled either the longstanding and recently concluded Sudanese Civil War or the Darfur conflict and are located mainly in Chad, Uganda, Ethiopia, and Kenya.
