Nelson Rolihlahla Mandela 18 July 1918 – 5 December 2013) was a South African anti-apartheid activist and politician who served as the first president of South Africa from 1994 to 1999. He was the country's first black head of state and the first elected in a fully representative democratic election.

Rolihlahla was Mandela ’s birth name: it comes from the isiXhosa name that means “pulling the branch of a tree”, but colloquially it means “troublemaker”. His father gave him this name.

Nelson was given to him on his first day at school by his teacher, Miss Mdingane. Giving African children English names was a custom among Africans in those days and was influenced by British colonials who could not easily, and often would not, pronounce African names. It is unclear why Miss Mdingane chose the name “Nelson” for Mr Mandela.

Madiba is the name of the clan of which Mr Mandela was a member. A clan name is much more important than a surname as it refers to the ancestor from which a person is descended. Madiba was the name of a Thembu chief who ruled in the Transkei in the 18th century. It is considered very polite to use someone’s clan name.

Tata is a isiXhosa word that means “father” and is a term of endearment that many South Africans use for Mr Mandela. Since he was a father figure to many, they call him Tata regardless of their own age.
