Nelson Mandela famously led a successful campaign against apartheid in South Africa. His dedication to ending racial segregation took him from activism to imprisonment for 27 years. Upon his release, Mandela became the country’s first black president in 1994 and united the nation under the principles of reconciliation and peace. His efforts significantly contributed to dismantling the systemic oppression of non-white South Africans, earning him the Nobel Peace Prize in 1993. Mandela's legacy continues to inspire anti-racism movements globally.
