A video believed to be former South African President Nelson Mandela’s first television interview ever has been released by the Nelson Mandela Foundation, an organization devoted to preserving the icon’s memory.

The foundation, Reuters reports, said the video was from 1956, when Mandela would have been 37. At the time, he was among the more than 150 antiapartheid political activists who had been rounded up on sedition charges, bringing international attention to the racist regime in South Africa.

“We have always regarded it as wrong for one racial group to dominate another racial group,” the bearded man believed to be Mandela says in the video. “From the very beginning, the African National Congress has fought without hesitation against all forms of racial discrimination, and we will continue to do so until freedom is achieved.”

Mandela would go on to be imprisoned for nearly 30 years until the twilight of the apartheid era, in 1990. He was elected South Africa’s President in 1994.
