"Rainbow nation" is a term coined by Archbishop Desmond Tutu to describe post-apartheid South Africa after South Africa's first democratic election in 1994.
The phrase was elaborated upon by President Nelson Mandela in his first month of office, when he proclaimed: "Each of us is as intimately attached to the soil of this beautiful country as are the famous jacaranda trees of Pretoria and the mimosa trees of the bushveld – a rainbow nation at peace with itself and the world."[1]
