Republic of Congo country profile

Civil wars and militia conflicts have plagued the Republic of Congo, also known as Congo-Brazzaville since its independence from France.

Nearly half the population lives in poverty, according to the World Bank, even though it is one of sub-Saharan Africa's main oil producers.

Oil is the mainstay of the economy. In recent years the country has tried to increase financial transparency in the sector.

President: Denis Sassou Nguesso

Denis Sassou Nguesso is one of Africa's longest-serving leaders, having first come to power almost four decades ago.

He was installed as president by the military in 1979 but lost his position in the first multi-party elections in 1992.

He returned to power in 1997 after a brief civil war in which he was backed by Angolan troops.

During his first presidency, he loosened links with the Soviet bloc and gave Western companies roles in oil exploration and production.

The Republic of Congo has a varied media landscape with around 20 TV channels, 40 radio stations and 20 newspapers. However, many media outlets, especially TV channels, have close ties to government allies.

The country's authoritarian government "routinely pressures, threatens and incarcerates" journalists, says Freedom House.
