The Significance of July 18
Nelson Rolihlahla Mandela was born on July 18, 1918, in the small village of Mvezo in South Africa’s Transkei region. He joined the African National Congress in 1944 and spent decades organizing resistance to apartheid before being arrested in 1962. He served 27 years in prison, 18 of them on Robben Island, before being released in 1990. Rather than seeking retribution, he negotiated a peaceful transition to democracy and won South Africa’s first free election in 1994. The United Nations designated July 18 as International Nelson Mandela Day in 2009, asking people everywhere to spend 67 minutes in service to their communities — one minute for each year of Mandela’s public life.
