The Zulu are the largest South African ethnic group of an estimated 10-11 million people who live mainly in the province of KwaZulu-Natal, South Africa. Small numbers also live in Zimbabwe, Zambia, and Mozambique. Their language, Zulu, is a Bantu language; more specifically, part of the Nguni subgroup. The Zulu Kingdom played a major role in South African History during the 19th and 20th centuries. Under apartheid, Zulu people were classed as third-class citizens and suffered from state sanctioned discrimination. They remain today the most numerous ethnic group in South Africa, and now have equal rights along with all other citizens.
