In 1962 Nelson Mandela travelled to Ethiopia for three months of military training under the name of David Motsamayi.
In his autobiography, Mandela speaks fondly about Ethiopia as a country that inspired him to continue his struggle against apartheid.
Officially, Mandela's presence at the camp was a secret, but the anti-apartheid activist could not hide who he was.
He was arrested shortly after returning from Ethiopia.
