uMkhonto weSizwe (Spear of the Nation or MK), the armed wing of the African National Congress (ANC), was jointly formed by leading members of the banned ANC and South African Communist Party (SACP) in 1961. The decision was endorsed by the Congress Alliance. MK launched into action that same year with a series of sabotage campaigns across major cities in South Africa and also established itself in exile. Several of its cadres trained in the Soviet Union, German Democratic Republic (GDR), set up safe houses and military training bases in friendly African countries. Several members and leading figures in the organisation were arrested in the 1960s and given long sentences or death severely crippling MK. The organisation’s early attempts to infiltrate its trained guerrillas back to South Africa were unsuccessful due to white minority led states surrounding South Africa which were hostile to the anti apartheid struggle. After the 1976 Uprising hundreds of young people who fled to exile swelled its ranks. MK stepped up its operations inside the 1980s with attacks across the country. As the ANC and the South African government moved towards a negotiated transition to democracy in the 1990s, MK suspended the armed struggle. After the 1994 elections MK forces were integrated into the South African National Defence Force (SANDF).
