Here are a few facts I know I hope it helps;
•Nelson Mandela was a politican who contributed to the end of apartheid.
• Him and Oliver Tambo established South's Africa's first black law firm in the 1950s
•On May 10th, 1994 he was inaugurated as South Africa's first democratically elected President
• In 1944, he only joined the African National Congress when he helped form the ANC Youth League
• He helped end Africa's apartheid system of racial segregation and ushered a transition to majority rule.
Hope this helped :)
