South Africa country profile
South Africa has one of the continent's biggest and most developed economies.
Up until 1994 it was ruled by a white minority government, which enforced a separation of races with its policy called apartheid.
The apartheid government eventually negotiated itself out of power after decades of international isolation, armed opposition and mass protests.
The democratically-elected leadership encouraged reconciliation and set about redressing social imbalances, but the economy has struggled.

President: Cyril Ramaphosa
Cyril Ramaphosa was elected president by parliament in February 2018 after his predecessor, Jacob Zuma, resigned.
A successful businessman, Mr Ramaphosa was picked as leader of the ruling African National Congress (ANC) a few months earlier.
He inherited a struggling economy, a divided party and the problem of entrenched corruption.
Unlike many senior party figures of his generation, Mr Ramaphosa was not driven into exile for opposing apartheid.
He fought the injustices of white minority rule from within South Africa, most prominently by defending the rights of black miners as leader of the National Union of Mineworkers (NUM).
He was heavily involved in talks ending apartheid and played an important role in the drafting of South Africa's post-apartheid constitution.
After missing out on becoming then President Nelson Mandela's deputy, Mr Ramaphosa withdrew from active political life, switching focus to business.
South Africa is the continent's major media player, and its broadcasters and press reflect the diversity of its people.
Established state-run and commercial TV broadcast nationally, and hundreds of thousands of viewers subscribe to satellite and cable. South Africa-based MultiChoice markets satellite pay-TV in dozens of African countries.
