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 peaceplan for the entire region. Namibia has been governed by SWAPO since the country won independence in 1990, though the party has dropped much of its Marxist ideology. Prime Minister Hage GEINGOB was elected president in 2014 in a landslide victory, replacing Hifikepunye POHAMBA who stepped down after serving two terms. SWAPO retained its parliamentary super majority in the 2014 elections and established a system of gender parity in parliamentary positions.
