South Africa occupied the German colony of South-West Africa during World War I and administered it as a mandate until after World War II, when it annexed the territory. In 1966 the Marxist South-West Africa People's Organization (SWAPO) guerrilla group launched a war of independence for the area that became Namibia, but it was not until 1988 that South Africa agreed to end its administration in accordance with a UN peace plan for the entire region. Namibia has been governed by SWAPO since the country won independence in 1990. Hifikepunye POHAMBA was elected president in November 2004 in a landslide victory replacing Sam NUJOMA who led the country during its first 14 years of self rule. POHAMBA was reelected in November 2009. - The World Factbook
