Umkhonto we Sizwe (abbreviated as
MK,
Zulu for "Spear of the Nation") was the armed wing of the
African National Congress (ANC), co-founded by
Nelson Mandela in the wake of the
Sharpeville massacre. Its founding represented the conviction in the face of the massacre that the ANC could no longer limit itself to nonviolent protest; its mission was to fight against the South African government. After warning the South African government in June 1961 of its intent to resist further acts of terror if the government did not take steps toward constitutional reform and increase political rights, MK launched its first attacks against government installations on 16 December 1961. It was subsequently classified as a
terrorist organisation by the South African government and the United States, and banned.
