DR Congo country profile
The recent history of the Democratic Republic of Congo (DR Congo) has been one of civil war and corruption.
DR Congo is a vast country with immense economic resources and, until recently, has been at the centre of what some observers call "Africa's world war", with widespread civilian suffering the result.
The war claimed an up to six million lives, either as a direct result of fighting or because of disease and malnutrition.
The war had an economic as well as a political side. Fighting was fuelled by the country's vast mineral wealth, with all sides taking advantage of the anarchy to plunder natural resources.
Some militias fight on in the east, where a large United Nations force is struggling to keep the peace.
President: Joseph Kabila
Joseph Kabila became president when his father Laurent was assassinated in 2001. He was elected in 2006, and secured another term in controversial elections in 2011.
He refused to leave office when his term expired in December 2016. Elections, twice delayed, are due to be held in December 2018, but opposition groups say they have little hope that the vote will be fair and credible.
Public rallies have been banned since September 2016, when dozens of demonstrators were killed.
The Congolese media operate against a backdrop of political power struggles and unrest.
Reporters Without Borders says journalists face arrest, threats and violence.
The press carries criticism of the government, and some publications reflect opposition party views.
Radio is the leading medium. Radio Okapi, partly run by the local UN mission, is an influential outlet.
