Mandela was laid to rest in his childhood village of Qunu, South Africa on Sunday December 15.
In keeping with tradition, Mandela was laid to rest in the afternoon, when the sun is at its highest.
Mandela was imprisoned for 27 years for defying the racist apartheid government that led South Africa for decades.
He emerged from prison in 1990 and became South Africa’s first Black president four years later, all the while promoting forgiveness and reconciliation.
