Who was the leader of Umkhonto we Sizwe (MK)?

The leader of Umkhonto we Sizwe (MK) was Nelson Mandela. He was a key figure in the struggle against apartheid in South Africa and played a crucial role in the formation of MK as the armed wing of the African National Congress (ANC) in 1961. MK was established to carry out sabotage against government installations as a form of resistance to the oppressive apartheid regime. Mandela's leadership in MK was part of his broader commitment to achieving inclusivity and equality in South Africa, and he served as the organization's first commander-in-chief. His involvement with MK marked a significant shift from non-violent protests to a more aggressive approach in the fight against apartheid.

In the context of the other figures, Steve Biko was a prominent anti-apartheid activist known for his role in the Black Consciousness Movement, but he was not associated with MK. Walter Sisulu was an important ANC leader and mentor to Mandela but did not lead MK. Oliver Tambo was another key leader of the ANC and played a significant role in the internationalization of the anti-apartheid struggle, but he was not the leader of MK. Thus, Mandela's leadership stands out as pivotal during a critical period in the resistance movement.
