Did Nelson Mandela worship the Illuminati?

No, Nelson Mandela is not an Illuminati.

The Illuminati was an organization (1776-1785) of enlightened intellectuals whose goal was the overthrow of an oppressive monarchy and the control of civil authorities by the Roman Catholic Church. They were very unsuccessful in their endeavor because that monarch successfully destroyed the organization and imprisoned their leadership.

The only Illuminati that exists today is the invention of writers and bloggers who enjoy feeding the imaginations of paranoid and naive individuals.
