Nongoloza's Children: Western Cape Prison Gangs During and After Apartheid, a book written as a monograph about the gangs from prisons of the Western Cape during and after racial isolation, was written for the Centre for the Study of Violence and Reconciliation by Jonny Steinberg.
[2] The author writes that he spent nine months of research at PollsMoor Prison Admission Center.
During the 1980s and 1990s all of them served their sentences in prisons throughout the Western Cape.
[3][4] According to Steinberg, The Numbers Gangs take their inspiration from the historical figure Nongoloza Mathebula, born Mzuzephi Mathebula, who became the founder of The Number Gangs in South Africa.
An early Johannesburg bandit, he built a quasi-military band of outlaws, welding his small army together with a simple but potent ideology of banditry-as-anti-colonial-resistance.
