The Inkatha National Cultural Liberation Movement, forerunner of the Inkatha Freedom Party (IFP) was founded at KwaNzimela, in northern KwaZulu. Inkatha emerged, along with the Black Consciousness Movement, to fill the vacuum in Black politics caused by the banning of the African National Congress (ANC) and Pan African Congress (PAC). Inkatha was transformed into a political party in July 1990, championing federalism as the best political option for South Africa. Chief Mangosuthu Buthelezi has been its leader since its inception. Other founding members included Rt. Rev. Bishop Dr. A.H. Zulu and former KwaZulu-Natal premier, Dr. Frank T. Mdlalose.   The party is currently the third largest party in the country.
