Sierra Leone country profile
Sierra Leone, a country in West Africa, has a special significance in the history of the transatlantic slave trade as the departure point for thousands of west African captives. The capital, Freetown, was founded as a home for repatriated former slaves in 1787.
But the country's modern history has been overshadowed by a brutal civil war that ended in 2002 with the help of Britain, the former colonial power, and a large United Nations peacekeeping mission.
Sierra Leone has experienced substantial economic growth in recent years, although the ruinous effects of the civil war continue to be felt.
The country is also rich in diamonds and other minerals. The trade in illicit gems, known as "blood diamonds" for their role in funding conflicts, perpetuated the civil war. The government has sought to crack down on the trade.
President Ernest Bai Koroma
Ernest Bai Koroma won a second and final term as president of Sierra Leone in November 2012, in the first elections the country has held without UN supervision since the end of the civil war in 2001.
His convincing win in the first round over main contender and former military ruler Julius Maada Bio confirms Sierra Leone's transition from failed state to democracy with a fast-growing economy, although the president still faces the challenge of widespread poverty.
President Koroma, an insurance broker by profession, has pursued free-market policies and encouraged foreign investment to rebuild the damage caused by the civil war.
His predecessor, Ahmad Tejan Kabbah of the now-opposition Sierra Leone People's Party, ended the war by inviting in first Nigerian and then British troops to drive out rebel groups. He stepped down in 2007 after serving the maximum two permitted consecutive terms.
Media freedom in Sierra Leone has its limits; media rights monitors say high-level corruption is a taboo topic, with officials using libel laws to target errant journalists.
Challenges facing broadcasters include unreliable power supplies, poor funding and low advertising revenues. There are dozens of radio stations, most of them privately owned.
Dozens of newspapers are published in Freetown, despite low literacy levels.
