During the late 1950s and early 1960s, pressure for global decolonisation and national self-determination began mounting on the African continent; these factors had a radical impact on South West African nationalism. Early nationalist organisations such as the South West African National Union (SWANU) and South West African People's Organisation (SWAPO) made determined attempts to establish indigenous political structures for an independent South West Africa. In 1966, following the ICJ's controversial ruling that it had no legal standing to consider the question of South African rule, SWAPO launched an armed insurgency that escalated into part of a wider regional conflict known as the South African Border War.
