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: Julius Maada Bio

Julius Maada Bio won a second term as president in June 2023 in hotly disputed presidential elections, with the opposition claiming voting irregularities and international election observers highlighting problems with transparency in the tallying of votes.

Official figures gave Mr Bio, of the Sierra Leone People's Party, 56% of the vote. His main rival, Samura Kamara, of the All People's Congress (APC), trailed far behind with 41%.

President Bio, a retired army brigadier took part in a military coup during the country's civil war in 1992, only to overthrow the military junta itself in 1996 and pave the way for free elections that year.

The rivalry between him and Dr Kamara was a repeat of the closely fought 2018 election, which went to a second round.

The campaign took place against a backdrop of a troubled economy, the rising cost of living and concerns about national unity.

Mr Bio, who blamed the country's woes on external factors such as the coronavirus pandemic and the war in Ukraine, now has the task of solving these problems.

The election is the fifth since Sierra Leone's brutal 11-year civil war officially ended in 2002. But since then the country has had a tradition of largely peaceful, free and credible elections, according to Marcella Samba Sesay, chairperson of the non-governmental organisation National Elections Watch.

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.

1787 - Following British defeat in the American Revolutionary War, thousands of Black Loyalists are settled in Canada, the West Indies or come to London. British philanthropists establish a settlement in Sierra Leone with the aim of lifting them out of poverty. British government officials are also involved, although their interest is in resettling a large group of poor citizens elsewhere away from London. This first settlement is attacked by locals, and struggles.

1792 - Black Loyalists are settled in Nova Scotia, Canada, after the American Revolution but face harsh northern winters and racial discrimination. Helped by philanthropists, nearly 1,200 decide to move to Sierra Leone and build the settlement of Freetown.
