Bonjour demain j'ai un petite oral sur Nelson Mandela et j'aimerais avoir vos avis ou vos corrections sur ce que j'ai fais : Nelson Mandela was born in 1918 in South Africa. At this moment, this country was part of the British Empire and was ruled by the white government. This government had created a political and social system where only whites had political rights. In 1948, the right-wing National Party came to power and set up the separation between blacks and whites “legal”. This separation is called the “apartheid”.
