Solomon Kalushi Mahlangu (10 July 1956 – 6 April 1979) was a South African operative of the African National Congress militant wing, Umkhonto we Sizwe (MK). He was convicted of murder and hanged in 1979. His father left in 1962 and as a result he was raised by his mother, a domestic worker. He attended Mamelodi High School up to Standard 8 (his tenth year of school), but his education was interrupted in 1976 by the riots of the Soweto uprising that resulted in school closures.
By the end of 1976 many hundreds of youths had been killed, including a 12-year-old schoolboy named Hector Petersen, and more than 2 000 wounded. Thousands more had been prosecuted or detained, and banning orders had been imposed. A large number of South Africans went abroad, often secretly, many of them vowing to pursue the struggle. One was Solomon Mahlangu, who left his home one night in great secrecy.
Mahlangu underwent military training as a soldier of Umkhonto we Sizwe (MK), and was then immediately tasked to return to South Africa to assist with student protests being planned to commemorate the 1976 uprising. In early 1977, he and two other MK soldiers, Monty Motloung and George Mahlangu, travelled from Angola to Mozambique, from where they infiltrated South Africa
