African National Congress is a national liberation movement, formed to unite the African people and spearhead the struggle for fundamental political, social, and economic change. For ten decades, it has led the struggle against racism and oppression, organizing mass resistance, mobilizing the international community, and taking up the armed struggle against apartheid. African National Congress achieved a decisive democratic breakthrough in the 1994 elections, where it was given a firm mandate to negotiate a new democratic Constitution for South Africa. The new Constitution was adopted in 1996. It was re-elected in 1999 to national and provincial government with an increased mandate. The policies of African National Congress are determined by its membership and its leadership is accountable to the membership. Membership of African National Congress is open to all South Africans above the age of 18 years, irrespective of race, color, and creed, who accept its principles, policies, and program. African National Congress was formed in 1912 and is based in Johannesburg, South Africa.
